public class JsonPointer extends Object
TreeNode.at(com.fasterxml.jackson.core.JsonPointer)
).
It may be used in future for filtering of streaming JSON content
as well (not implemented yet for 2.3).
Instances are fully immutable and can be shared, cached.

Modifier and Type | Field and Description |
---|---|
protected String |
_asString
We will retain representation of the pointer, as a String,
so that
toString() should be as efficient as possible. |
protected int |
_matchingElementIndex |
protected String |
_matchingPropertyName |
protected JsonPointer |
_nextSegment
Reference to rest of the pointer beyond currently matching
segment (if any); null if this pointer refers to a matching
segment.
|
protected static JsonPointer |
EMPTY
Marker instance used to represent segment that matches current
node or position.
|
Modifier | Constructor and Description |
---|---|
protected |
JsonPointer()
Constructor used for creating "empty" instance, used to represent
state that matches current node.
|
protected |
JsonPointer(String fullString,
String segment,
JsonPointer next)
Constructor used for creating non-empty Segments

_parseQuotedTail(String input,
int i)
Method called to parse tail of pointer path, when a potentially
escaped character has been seen.
|
protected static JsonPointer |
_parseTail(String input) |

compile(String input)
Factory method that parses given input and construct matching pointer
instance, if it represents a valid JSON Pointer: if not, a
IllegalArgumentException is thrown. |
