Method Detail

getCodec

public ObjectCodec getCodec()

Description copied from class: JsonParser

Accessor for ObjectCodec associated with this parser, if any. Codec is used by JsonParser.readValueAs(Class) method (and its variants).

Specified by:

getCodec in class JsonParser

setCodec

public void setCodec(ObjectCodec c)

Description copied from class: JsonParser

Setter that allows defining ObjectCodec associated with this parser, if any. Codec is used by JsonParser.readValueAs(Class) method (and its variants).

Specified by:

setCodec in class JsonParser

releaseBuffered

public int releaseBuffered(Writer w)
                    throws IOException

Description copied from class: JsonParser

Method that can be called to push back any content that has been read but not consumed by the parser. This is usually done after reading all content of interest using parser. Content is released by writing it to given writer if possible; if underlying input is char-based it can released, if not (byte-based) it can not.

Overrides:

releaseBuffered in class JsonParser

Returns:

-1 if the underlying content source is not char-based (that is, input can not be sent to Writer; otherwise number of chars released (0 if there was nothing to release)

Throws:

IOException - if write using Writer threw exception

getInputSource

public Object getInputSource()

Description copied from class: JsonParser

Method that can be used to get access to object that is used to access input being parsed; this is usually either InputStream or Reader, depending on what parser was constructed with. Note that returned value may be null in some cases; including case where parser implementation does not want to exposed raw source to caller. In cases where input has been decorated, object returned here is the decorated version; this allows some level of interaction between users of parser and decorator object.

In general use of this accessor should be considered as "last effort", i.e. only used if no other mechanism is applicable.

Overrides:

getInputSource in class JsonParser

loadMore

protected boolean loadMore()
                    throws IOException

Specified by:

loadMore in class ParserBase

Throws:

IOException

getNextChar

protected char getNextChar(String eofMsg)
                    throws IOException

Throws:

IOException

_closeInput

protected void _closeInput()
                    throws IOException

Specified by:

_closeInput in class ParserBase

Throws:

IOException

_releaseBuffers

protected void _releaseBuffers()
                        throws IOException

Method called to release internal buffers owned by the base reader. This may be called along with _closeInput() (for example, when explicitly closing this reader instance), or separately (if need be).

Overrides:

_releaseBuffers in class ParserBase

Throws:

IOException

getText

public final String getText()
                     throws IOException

Method for accessing textual representation of the current event; if no current event (before first call to nextToken(), or after encountering end-of-input), returns null. Method can be called for any event.

Specified by:

getText in class ParserMinimalBase

Throws:

IOException

getValueAsString

public final String getValueAsString()
                              throws IOException

Description copied from class: JsonParser

Method that will try to convert value of current token to a String. JSON Strings map naturally; scalar values get converted to their textual representation. If representation can not be converted to a String value (including structured types like Objects and Arrays and null token), default value of null will be returned; no exceptions are thrown.

Overrides:

getValueAsString in class ParserMinimalBase

Throws:

IOException

getValueAsString

public final String getValueAsString(String defValue)
                              throws IOException

Description copied from class: JsonParser

Method that will try to convert value of current token to a String. JSON Strings map naturally; scalar values get converted to their textual representation. If representation can not be converted to a String value (including structured types like Objects and Arrays and null token), specified default value will be returned; no exceptions are thrown.

Overrides:

getValueAsString in class ParserMinimalBase

Throws:

IOException

_getText2

protected final String _getText2(JsonToken t)

getTextCharacters

public final char[] getTextCharacters()
                               throws IOException

Description copied from class: JsonParser

Method similar to JsonParser.getText(), but that will return underlying (unmodifiable) character array that contains textual value, instead of constructing a String object to contain this information. Note, however, that:

• Textual contents are not guaranteed to start at index 0 (rather, call JsonParser.getTextOffset()) to know the actual offset
• Length of textual contents may be less than the length of returned buffer: call JsonParser.getTextLength() for actual length of returned content.

Note that caller MUST NOT modify the returned character array in any way -- doing so may corrupt current parser state and render parser instance useless.

The only reason to call this method (over JsonParser.getText()) is to avoid construction of a String object (which will make a copy of contents).

Specified by:

getTextCharacters in class ParserMinimalBase

Throws:

IOException

getTextLength

public final int getTextLength()
                        throws IOException

Description copied from class: JsonParser

Accessor used with JsonParser.getTextCharacters(), to know length of String stored in returned buffer.

Specified by:

getTextLength in class ParserMinimalBase

Returns:

Number of characters within buffer returned by JsonParser.getTextCharacters() that are part of textual content of the current token.

Throws:

IOException

getTextOffset

public final int getTextOffset()
                        throws IOException

Description copied from class: JsonParser

Accessor used with JsonParser.getTextCharacters(), to know offset of the first text content character within buffer.

Specified by:

getTextOffset in class ParserMinimalBase

Returns:

Offset of the first character within buffer returned by JsonParser.getTextCharacters() that is part of textual content of the current token.

Throws:

IOException

getBinaryValue

public byte[] getBinaryValue(Base64Variant b64variant)
                      throws IOException

Description copied from class: JsonParser

Method that can be used to read (and consume -- results may not be accessible using other methods after the call) base64-encoded binary data included in the current textual JSON value. It works similar to getting String value via JsonParser.getText() and decoding result (except for decoding part), but should be significantly more performant.

Note that non-decoded textual contents of the current token are not guaranteed to be accessible after this method is called. Current implementation, for example, clears up textual content during decoding. Decoded binary content, however, will be retained until parser is advanced to the next event.

Overrides:

getBinaryValue in class ParserBase

Parameters:

b64variant - Expected variant of base64 encoded content (see Base64Variants for definitions of "standard" variants).

Returns:

Decoded binary data

Throws:

IOException

readBinaryValue

public int readBinaryValue(Base64Variant b64variant,
                           OutputStream out)
                    throws IOException

Description copied from class: JsonParser

Similar to JsonParser.readBinaryValue(OutputStream) but allows explicitly specifying base64 variant to use.

Overrides:

readBinaryValue in class JsonParser

Parameters:

b64variant - base64 variant to use

out - Output stream to use for passing decoded binary data

Returns:

Number of bytes that were decoded and written via OutputStream

Throws:

IOException

_readBinary

protected int _readBinary(Base64Variant b64variant,
                          OutputStream out,
                          byte[] buffer)
                   throws IOException

Throws:

IOException

nextToken

public final JsonToken nextToken()
                          throws IOException

Description copied from class: JsonParser

Main iteration method, which will advance stream enough to determine type of the next token, if any. If none remaining (stream has no content other than possible white space before ending), null will be returned.

Specified by:

nextToken in class ParserMinimalBase

Returns:

Next token from the stream, if any found, or null to indicate end-of-input

Throws:

IOException

nextFieldName

public boolean nextFieldName(SerializableString sstr)
                      throws IOException

Description copied from class: JsonParser

Method that fetches next token (as if calling JsonParser.nextToken()) and verifies whether it is JsonToken.FIELD_NAME with specified name and returns result of that comparison. It is functionally equivalent to:

  return (nextToken() == JsonToken.FIELD_NAME) && str.getValue().equals(getCurrentName());

but may be faster for parser to verify, and can therefore be used if caller expects to get such a property name from input next.

Overrides:

nextFieldName in class JsonParser

Parameters:

sstr - Property name to compare next token to (if next token is JsonToken.FIELD_NAME)

Throws:

IOException

nextFieldName

public String nextFieldName()
                     throws IOException

Description copied from class: JsonParser

Method that fetches next token (as if calling JsonParser.nextToken()) and verifies whether it is JsonToken.FIELD_NAME; if it is, returns same as JsonParser.getCurrentName(), otherwise null.

Overrides:

nextFieldName in class JsonParser

Throws:

IOException

_isNextTokenNameMaybe

protected boolean _isNextTokenNameMaybe(int i,
                                        String nameToMatch)
                                 throws IOException

Throws:

IOException

nextTextValue

public final String nextTextValue()
                           throws IOException

Description copied from class: JsonParser

Method that fetches next token (as if calling JsonParser.nextToken()) and if it is JsonToken.VALUE_STRING returns contained String value; otherwise returns null. It is functionally equivalent to:

  return (nextToken() == JsonToken.VALUE_STRING) ? getText() : null;

but may be faster for parser to process, and can therefore be used if caller expects to get a String value next from input.

Overrides:

nextTextValue in class JsonParser

Throws:

IOException

nextIntValue

public final int nextIntValue(int defaultValue)
                       throws IOException

Description copied from class: JsonParser

Method that fetches next token (as if calling JsonParser.nextToken()) and if it is JsonToken.VALUE_NUMBER_INT returns 32-bit int value; otherwise returns specified default value It is functionally equivalent to:

  return (nextToken() == JsonToken.VALUE_NUMBER_INT) ? getIntValue() : defaultValue;

but may be faster for parser to process, and can therefore be used if caller expects to get a String value next from input.

Overrides:

nextIntValue in class JsonParser

Throws:

IOException

nextLongValue

public final long nextLongValue(long defaultValue)
                         throws IOException

Description copied from class: JsonParser

Method that fetches next token (as if calling JsonParser.nextToken()) and if it is JsonToken.VALUE_NUMBER_INT returns 64-bit long value; otherwise returns specified default value It is functionally equivalent to:

  return (nextToken() == JsonToken.VALUE_NUMBER_INT) ? getLongValue() : defaultValue;

but may be faster for parser to process, and can therefore be used if caller expects to get a String value next from input.

Overrides:

nextLongValue in class JsonParser

Throws:

IOException

nextBooleanValue

public final Boolean nextBooleanValue()
                               throws IOException

Description copied from class: JsonParser

Method that fetches next token (as if calling JsonParser.nextToken()) and if it is JsonToken.VALUE_TRUE or JsonToken.VALUE_FALSE returns matching Boolean value; otherwise return null. It is functionally equivalent to:

  JsonToken t = nextToken();
  if (t == JsonToken.VALUE_TRUE) return Boolean.TRUE;
  if (t == JsonToken.VALUE_FALSE) return Boolean.FALSE;
  return null;

but may be faster for parser to process, and can therefore be used if caller expects to get a String value next from input.

Overrides:

nextBooleanValue in class JsonParser

Throws:

IOException

_parsePosNumber

protected final JsonToken _parsePosNumber(int ch)
                                   throws IOException

Initial parsing method for number values. It needs to be able to parse enough input to be able to determine whether the value is to be considered a simple integer value, or a more generic decimal value: latter of which needs to be expressed as a floating point number. The basic rule is that if the number has no fractional or exponential part, it is an integer; otherwise a floating point number.

Because much of input has to be processed in any case, no partial parsing is done: all input text will be stored for further processing. However, actual numeric value conversion will be deferred, since it is usually the most complicated and costliest part of processing.

Throws:

IOException

protected char _decodeEscaped()
                       throws IOException
