protected boolean	_allowMultipleMatches Flag that determines whether filtering will continue after the first match is indicated or not: if `false`, output is based on just the first full match (returning TokenFilter.INCLUDE_ALL) and no more checks are made; if `true` then filtering will be applied as necessary until end of content.
protected TokenFilterContext	_filterContext Although delegate has its own output context it is not sufficient since we actually have to keep track of excluded (filtered out) structures as well as ones delegate actually outputs.
protected boolean	_includeImmediateParent Deprecated.
protected boolean	_includePath Flag that determines whether path leading up to included content should also be automatically included or not.
protected TokenFilter	_itemFilter State that applies to the item within container, used where applicable.
protected int	_matchCount Number of tokens for which TokenFilter.INCLUDE_ALL has been returned
protected TokenFilter	rootFilter Object consulted to determine whether to write parts of content generator is asked to write or not.

void	writeString(char[] text, int offset, int len) Method for outputting a String value.
void	writeString(SerializableString value) Method similar to JsonGenerator.writeString(String), but that takes SerializableString which can make this potentially more efficient to call as generator may be able to reuse quoted and/or encoded representation.

Field Detail

rootFilter

protected TokenFilter rootFilter

Object consulted to determine whether to write parts of content generator is asked to write or not.

_allowMultipleMatches

protected boolean _allowMultipleMatches

Flag that determines whether filtering will continue after the first match is indicated or not: if `false`, output is based on just the first full match (returning TokenFilter.INCLUDE_ALL) and no more checks are made; if `true` then filtering will be applied as necessary until end of content.

_includePath

protected boolean _includePath

Flag that determines whether path leading up to included content should also be automatically included or not. If `false`, no path inclusion is done and only explicitly included entries are output; if `true` then path from main level down to match is also included as necessary.

_includeImmediateParent

@Deprecated
protected boolean _includeImmediateParent

Deprecated.

_filterContext

protected TokenFilterContext _filterContext

Although delegate has its own output context it is not sufficient since we actually have to keep track of excluded (filtered out) structures as well as ones delegate actually outputs.

_itemFilter

protected TokenFilter _itemFilter

State that applies to the item within container, used where applicable. Specifically used to pass inclusion state between property name and property, and also used for array elements.

_matchCount

protected int _matchCount

Number of tokens for which TokenFilter.INCLUDE_ALL has been returned

writeStartArray

public void writeStartArray()
                     throws IOException

Description copied from class: JsonGenerator

Method for writing starting marker of a Array value (for JSON this is character '['; plus possible white space decoration if pretty-printing is enabled).

Array values can be written in any context where values are allowed: meaning everywhere except for when a field name is expected.

Overrides:

writeStartArray in class JsonGeneratorDelegate

Throws:

IOException

writeStartArray

public void writeStartArray(int size)
                     throws IOException

Description copied from class: JsonGenerator

Method for writing start marker of an Array value, similar to JsonGenerator.writeStartArray(), but also specifying how many elements will be written for the array before calling JsonGenerator.writeEndArray().

Default implementation simply calls JsonGenerator.writeStartArray().

Overrides:

writeStartArray in class JsonGeneratorDelegate

Parameters:

size - Number of elements this array will have: actual number of values written (before matching call to JsonGenerator.writeEndArray() MUST match; generator MAY verify this is the case.

Throws:

IOException

writeEndArray

public void writeEndArray()
                   throws IOException

Description copied from class: JsonGenerator

Method for writing closing marker of a JSON Array value (character ']'; plus possible white space decoration if pretty-printing is enabled).

Marker can be written if the innermost structured type is Array.

Overrides:

writeEndArray in class JsonGeneratorDelegate

Throws:

IOException

writeStartObject

public void writeStartObject()
                      throws IOException

Description copied from class: JsonGenerator

Method for writing starting marker of a JSON Object value (character '{'; plus possible white space decoration if pretty-printing is enabled).

Object values can be written in any context where values are allowed: meaning everywhere except for when a field name is expected.

Overrides:

writeStartObject in class JsonGeneratorDelegate

Throws:

IOException

writeEndObject

public void writeEndObject()
                    throws IOException

Description copied from class: JsonGenerator

Method for writing closing marker of a JSON Object value (character '}'; plus possible white space decoration if pretty-printing is enabled).

Marker can be written if the innermost structured type is Object, and the last written event was either a complete value, or START-OBJECT marker (see JSON specification for more details).

Overrides:

writeEndObject in class JsonGeneratorDelegate

Throws:

IOException

writeFieldName

public void writeFieldName(String name)
                    throws IOException

Description copied from class: JsonGenerator

Method for writing a field name (JSON String surrounded by double quotes: syntactically identical to a JSON String value), possibly decorated by white space if pretty-printing is enabled.

Field names can only be written in Object context (check out JSON specification for details), when field name is expected (field names alternate with values).

Overrides:

writeFieldName in class JsonGeneratorDelegate

Throws:

IOException

writeFieldName

public void writeFieldName(SerializableString name)
                    throws IOException

Description copied from class: JsonGenerator

Method similar to JsonGenerator.writeFieldName(String), main difference being that it may perform better as some of processing (such as quoting of certain characters, or encoding into external encoding if supported by generator) can be done just once and reused for later calls.

Default implementation simple uses unprocessed name container in serialized String; implementations are strongly encouraged to make use of more efficient methods argument object has.

Overrides:

writeFieldName in class JsonGeneratorDelegate

Throws:

IOException

writeString

public void writeString(String value)
                 throws IOException

Description copied from class: JsonGenerator

Method for outputting a String value. Depending on context this means either array element, (object) field value or a stand alone String; but in all cases, String will be surrounded in double quotes, and contents will be properly escaped as required by JSON specification.

Overrides:

writeString in class JsonGeneratorDelegate

Throws:

IOException

writeString

public void writeString(char[] text,
                        int offset,
                        int len)
                 throws IOException

Description copied from class: JsonGenerator

Method for outputting a String value. Depending on context this means either array element, (object) field value or a stand alone String; but in all cases, String will be surrounded in double quotes, and contents will be properly escaped as required by JSON specification.

Overrides:

writeString in class JsonGeneratorDelegate

Throws:

IOException

writeString

public void writeString(SerializableString value)
                 throws IOException

Description copied from class: JsonGenerator

Method similar to JsonGenerator.writeString(String), but that takes SerializableString which can make this potentially more efficient to call as generator may be able to reuse quoted and/or encoded representation.

Default implementation just calls JsonGenerator.writeString(String); sub-classes should override it with more efficient implementation if possible.

Overrides:

writeString in class JsonGeneratorDelegate

Throws:

IOException

writeRawUTF8String

public void writeRawUTF8String(byte[] text,
                               int offset,
                               int length)
                        throws IOException

Description copied from class: JsonGenerator

Method similar to JsonGenerator.writeString(String) but that takes as its input a UTF-8 encoded String that is to be output as-is, without additional escaping (type of which depends on data format; backslashes for JSON). However, quoting that data format requires (like double-quotes for JSON) will be added around the value if and as necessary.

Note that some backends may choose not to support this method: for example, if underlying destination is a Writer using this method would require UTF-8 decoding. If so, implementation may instead choose to throw a UnsupportedOperationException due to ineffectiveness of having to decode input.

Overrides:

writeRawUTF8String in class JsonGeneratorDelegate

Throws:

IOException

writeUTF8String

public void writeUTF8String(byte[] text,
                            int offset,
                            int length)
                     throws IOException

Description copied from class: JsonGenerator

Method similar to JsonGenerator.writeString(String) but that takes as its input a UTF-8 encoded String which has not been escaped using whatever escaping scheme data format requires (for JSON that is backslash-escaping for control characters and double-quotes; for other formats something else). This means that textual JSON backends need to check if value needs JSON escaping, but otherwise can just be copied as is to output. Also, quoting that data format requires (like double-quotes for JSON) will be added around the value if and as necessary.

Note that some backends may choose not to support this method: for example, if underlying destination is a Writer using this method would require UTF-8 decoding. In this case generator implementation may instead choose to throw a UnsupportedOperationException due to ineffectiveness of having to decode input.

Overrides:

writeUTF8String in class JsonGeneratorDelegate

Throws:

IOException

writeRaw

public void writeRaw(String text)
              throws IOException

Description copied from class: JsonGenerator

Method that will force generator to copy input text verbatim with no modifications (including that no escaping is done and no separators are added even if context [array, object] would otherwise require such). If such separators are desired, use JsonGenerator.writeRawValue(String) instead.

Note that not all generator implementations necessarily support such by-pass methods: those that do not will throw UnsupportedOperationException.

Overrides:

writeRaw in class JsonGeneratorDelegate

Throws:

IOException

writeRaw

public void writeRaw(String text,
                     int offset,

              throws IOException

Description copied from class: JsonGenerator

Method that will force generator to copy input text verbatim with no modifications (including that no escaping is done and no separators are added even if context [array, object] would otherwise require such). If such separators are desired, use JsonGenerator.writeRawValue(String) instead.

Note that not all generator implementations necessarily support such by-pass methods: those that do not will throw UnsupportedOperationException.

Overrides:

writeRaw in class JsonGeneratorDelegate

Throws:

IOException

writeRaw

public void writeRaw(SerializableString text)
              throws IOException

Description copied from class: JsonGenerator

Method that will force generator to copy input text verbatim with no modifications (including that no escaping is done and no separators are added even if context [array, object] would otherwise require such). If such separators are desired, use JsonGenerator.writeRawValue(String) instead.

Note that not all generator implementations necessarily support such by-pass methods: those that do not will throw UnsupportedOperationException.

The default implementation delegates to JsonGenerator.writeRaw(String); other backends that support raw inclusion of text are encouraged to implement it in more efficient manner (especially if they use UTF-8 encoding).

Overrides:

writeRaw in class JsonGeneratorDelegate

Throws:

IOException

writeRaw

public void writeRaw(char[] text,
                     int offset,
                     int len)
              throws IOException

Description copied from class: JsonGenerator

Method that will force generator to copy input text verbatim with no modifications (including that no escaping is done and no separators are added even if context [array, object] would otherwise require such). If such separators are desired, use JsonGenerator.writeRawValue(String) instead.

public void writeRaw(char c)
              throws IOException

Description copied from class: JsonGenerator

Method that will force generator to copy input text verbatim with no modifications (including that no escaping is done and no separators are added even if context [array, object] would otherwise require such). If such separators are desired, use JsonGenerator.writeRawValue(String) instead.

Note that not all generator implementations necessarily support such by-pass methods: those that do not will throw UnsupportedOperationException.

Overrides:

writeRaw in class JsonGeneratorDelegate

Throws:

IOException

writeRawValue

public void writeRawValue(String text)
                   throws IOException

Description copied from class: JsonGenerator

Method that will force generator to copy input text verbatim without any modifications, but assuming it must constitute a single legal JSON value (number, string, boolean, null, Array or List). Assuming this, proper separators are added if and as needed (comma or colon), and generator state updated to reflect this.

Overrides:

writeRawValue in class JsonGeneratorDelegate

Throws:

IOException

writeRawValue

public void writeRawValue(String text,
                          int offset,
                          int len)
                   throws IOException

Overrides:

writeBinary

public void writeBinary(Base64Variant b64variant,
                        byte[] data,
                        int offset,
                        int len)
                 throws IOException

Description copied from class: JsonGenerator

Method that will output given chunk of binary data as base64 encoded, as a complete String value (surrounded by double quotes). This method defaults

Note: because JSON Strings can not contain unescaped linefeeds, if linefeeds are included (as per last argument), they must be escaped. This adds overhead for decoding without improving readability. Alternatively if linefeeds are not included, resulting String value may violate the requirement of base64 RFC which mandates line-length of 76 characters and use of linefeeds. However, all JsonParser implementations are required to accept such "long line base64"; as do typical production-level base64 decoders.

Overrides:

writeBinary in class JsonGeneratorDelegate

Parameters:

b64variant - Base64 variant to use: defines details such as whether padding is used (and if so, using which character); what is the maximum line length before adding linefeed, and also the underlying alphabet to use.

Throws:

IOException

writeBinary

public int writeBinary(Base64Variant b64variant,
                       InputStream data,
                       int dataLength)
                throws IOException

Description copied from class: JsonGenerator

Method similar to JsonGenerator.writeBinary(Base64Variant,byte[],int,int), but where input is provided through a stream, allowing for incremental writes without holding the whole input in memory.

Overrides:

writeBinary in class JsonGeneratorDelegate

Parameters:

b64variant - Base64 variant to use

data - InputStream to use for reading binary data to write. Will not be closed after successful write operation

dataLength - (optional) number of bytes that will be available; or -1 to be indicate it is not known. If a positive length is given, data MUST provide at least that many bytes: if not, an exception will be thrown. Note that implementations need not support cases where length is not known in advance; this depends on underlying data format: JSON output does NOT require length, other formats may.

Returns:

Number of bytes read from data and written as binary payload

Throws:

IOException

writeNumber

public void writeNumber(short v)
                 throws IOException

Throws:

IOException

writeNumber

public void writeNumber(BigInteger v)
                 throws IOException

Description copied from class: JsonGenerator

Method for outputting given value as JSON number. Can be called in any context where a value is expected (Array value, Object field value, root-level value). Additional white space may be added around the value if pretty-printing is enabled.

Overrides:

writeNumber in class JsonGeneratorDelegate

Parameters:

Throws:

IOException

writeNumber

public void writeNumber(double v)
                 throws IOException

Description copied from class: JsonGenerator

Method for outputting indicate JSON numeric value. Can be called in any context where a value is expected (Array value, Object field value, root-level value). Additional white space may be added around the value if pretty-printing is enabled.

Overrides:

writeNumber in class JsonGeneratorDelegate

Parameters:

v - Number value to write

Throws:

IOException

writeNumber

public void writeNumber(float v)
                 throws IOException

Description copied from class: JsonGenerator

Method for outputting indicate JSON numeric value. Can be called in any context where a value is expected (Array value, Object field value, root-level value). Additional white space may be added around the value if pretty-printing is enabled.

Overrides:

writeNumber in class JsonGeneratorDelegate

Throws:

IOException

writeNumber

public void writeNumber(BigDecimal v)
                 throws IOException

Description copied from class: JsonGenerator

Method for outputting indicate JSON numeric value. Can be called in any context where a value is expected (Array value, Object field value, root-level value). Additional white space may be added around the value if pretty-printing is enabled.

Overrides:

writeNumber in class JsonGeneratorDelegate

Parameters:

writeNumber

public void writeNumber(String encodedValue)
                 throws IOException,
                        UnsupportedOperationException

Description copied from class: JsonGenerator

Write method that can be used for custom numeric types that can not be (easily?) converted to "standard" Java number types. Because numbers are not surrounded by double quotes, regular JsonGenerator.writeString(java.lang.String) method can not be used; nor JsonGenerator.writeRaw(java.lang.String) because that does not properly handle value separators needed in Array or Object contexts.

Note: because of lack of type safety, some generator implementations may not be able to implement this method. For example, if a binary JSON format is used, it may require type information for encoding; similarly for generator-wrappers around Java objects or JSON nodes. If implementation does not implement this method, it needs to throw UnsupportedOperationException.

Overrides:

writeNumber in class JsonGeneratorDelegate

Throws:

UnsupportedOperationException - If underlying data format does not support numbers serialized textually AND if generator is not allowed to just output a String instead (Schema-based formats may require actual number, for example)

IOException

                  throws IOException

Description copied from class: JsonGenerator

Method for outputting literal JSON boolean value (one of Strings 'true' and 'false'). Can be called in any context where a value is expected (Array value, Object field value, root-level value). Additional white space may be added around the value if pretty-printing is enabled.

Throws:

IOException

writeNull

public void writeNull()
               throws IOException

Description copied from class: JsonGenerator

public void writeOmittedField(String fieldName)
                       throws IOException

Default implementation does nothing.

Overrides:

writeOmittedField in class JsonGeneratorDelegate

Throws:

IOException

writeObjectId

public void writeObjectId(Object id)
                   throws IOException

Description copied from class: JsonGenerator

Method that can be called to output so-called native Object Id. Note that it may only be called after ensuring this is legal (with JsonGenerator.canWriteObjectId()), as not all data formats have native type id support; and some may only allow them in certain positions or locations. If output is not allowed by the data format in this position, a JsonGenerationException will be thrown.

Overrides:

writeObjectId in class JsonGeneratorDelegate

Throws:

IOException

writeObjectRef

public void writeObjectRef(Object id)
                    throws IOException

Description copied from class: JsonGenerator

Method that can be called to output references to native Object Ids. Note that it may only be called after ensuring this is legal (with JsonGenerator.canWriteObjectId()), as not all data formats have native type id support; and some may only allow them in certain positions or locations. If output is not allowed by the data format in this position, a JsonGenerationException will be thrown.

Overrides:

writeObjectRef in class JsonGeneratorDelegate

Throws:

IOException

writeTypeId

public void writeTypeId(Object id)
                 throws IOException

Description copied from class: JsonGenerator

Method that can be called to output so-called native Type Id. Note that it may only be called after ensuring this is legal (with JsonGenerator.canWriteTypeId()), as not all data formats have native type id support; and some may only allow them in certain positions or locations. If output is not allowed by the data format in this position, a JsonGenerationException will be thrown.

Overrides:
