## Uses of Class
com.fasterxml.jackson.core.JsonPointer

Packages that use JsonPointer
com.fasterxml.jackson.core: Main public API classes of the core streaming JSON processor: most importantly `JsonFactory` used for constructing JSON parser (`JsonParser`) and generator (`JsonGenerator`) instances.
com.fasterxml.jackson.core.filter

### Uses of JsonPointer in com.fasterxml.jackson.core

Fields in com.fasterxml.jackson.core declared as JsonPointer
`protected JsonPointer` JsonPointer.`_head` Reference from currently matching segment (if any) to node before leaf.
`protected JsonPointer` JsonPointer.`_nextSegment` Reference to rest of the pointer beyond currently matching segment (if any); null if this pointer refers to the matching segment.
`protected static JsonPointer` JsonPointer.`EMPTY` Marker instance used to represent segment that matches current node or position (that is, returns true for `matches()`).

Methods in com.fasterxml.jackson.core that return JsonPointer
`protected JsonPointer` JsonPointer.`_constructHead()`
`protected static JsonPointer` JsonPointer.`_parseTail(String fullPath)`
`JsonPointer` JsonPointer.`append(JsonPointer tail)` Mutant factory method that will return `tail` if `this` instance is "empty" pointer, OR `this` instance if `tail` is "empty" pointer, OR Newly constructed `JsonPointer` instance that starts with all segments of `this`, followed by all segments of `tail`.
`JsonPointer` JsonPointer.`appendIndex(int index)` ATTENTION!
`JsonPointer` JsonPointer.`appendProperty(String property)` ATTENTION!
`static JsonPointer` JsonPointer.`compile(String expr)` Factory method that parses given input and construct matching pointer instance, if it represents a valid JSON Pointer: if not, a `IllegalArgumentException` is thrown.
`static JsonPointer` JsonPointer.`empty()` Accessor for an "empty" expression, that is, one you can get by calling `compile(java.lang.String)` with "" (empty String).
`static JsonPointer` JsonPointer.`forPath(JsonStreamContext context, boolean includeRoot)` Factory method that will construct a pointer instance that describes path to location given `JsonStreamContext` points to.
`JsonPointer` JsonPointer.`head()` Accessor for getting a pointer instance that is identical to this instance except that the last segment has been dropped.
`JsonPointer` JsonPointer.`last()`
`JsonPointer` JsonPointer.`matchElement(int index)` Method that may be called to check whether the pointer head (first segment) matches specified Array index and if so, return `JsonPointer` that represents rest of the path after match.
`JsonPointer` JsonPointer.`matchProperty(String name)` Method that may be called to check whether the pointer head (first segment) matches specified Object property (by name) and if so, return `JsonPointer` that represents rest of the path after match.
`JsonPointer` JsonStreamContext.`pathAsPointer()` Factory method for constructing a `JsonPointer` that points to the current location within the stream that this context is for, excluding information about "root context" (only relevant for multi-root-value cases)
`JsonPointer` JsonStreamContext.`pathAsPointer(boolean includeRoot)` Factory method for constructing a `JsonPointer` that points to the current location within the stream that this context is for, optionally including "root value index"
`JsonPointer` JsonPointer.`tail()` Accessor for getting a "sub-pointer" (or sub-path), instance where current segment has been removed and pointer includes rest of the segments.
`static JsonPointer` JsonPointer.`valueOf(String expr)` Alias for `compile(java.lang.String)`; added to make instances automatically deserializable by Jackson databind.

Methods in com.fasterxml.jackson.core with parameters of type JsonPointer
`JsonPointer` JsonPointer.`append(JsonPointer tail)` Mutant factory method that will return `tail` if `this` instance is "empty" pointer, OR `this` instance if `tail` is "empty" pointer, OR Newly constructed `JsonPointer` instance that starts with all segments of `this`, followed by all segments of `tail`.
`TreeNode` TreeNode.`at(JsonPointer ptr)` Method for locating node specified by given JSON pointer instances.

Constructors in com.fasterxml.jackson.core with parameters of type JsonPointer
Constructor and Description

`JsonPointer(JsonPointer src, String newFullString, int newFullStringOffset)`
`JsonPointer(String fullString, int fullStringOffset, String segment, int matchIndex, JsonPointer next)`
`JsonPointer(String fullString, int fullStringOffset, String segment, JsonPointer next)`

### Uses of JsonPointer in com.fasterxml.jackson.core.filter

Fields in com.fasterxml.jackson.core.filter declared as JsonPointer
`protected JsonPointer` JsonPointerBasedFilter.`_pathToMatch`

Methods in com.fasterxml.jackson.core.filter with parameters of type JsonPointer
`protected JsonPointerBasedFilter` JsonPointerBasedFilter.`construct(JsonPointer pathToMatch, boolean includeAllElements)` Overridable factory method use for creating new instances by default `JsonPointerBasedFilter.includeElement(int)` and `JsonPointerBasedFilter.includeProperty(java.lang.String)` methods: needs to be overridden if sub-classing this class.
