JsonPointer ("The Adobe AEM Quickstart and Web Application.")

java.lang.Object
- com.fasterxml.jackson.core.JsonPointer

```
public class JsonPointer
extends java.lang.Object
```
Implementation of JSON Pointer specification. Pointer instances can be used to locate logical JSON nodes for things like tree traversal (see 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.

Since:

2.3

Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`JsonPointer`	`append(JsonPointer tail)`
`static JsonPointer`	`compile(java.lang.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.
`boolean`	`equals(java.lang.Object o)`
`int`	`getMatchingIndex()`
`java.lang.String`	`getMatchingProperty()`
`int`	`hashCode()`
`JsonPointer`	`head()` Accessor for getting a pointer instance that is identical to this instance except that the last segment has been dropped.
`JsonPointer`	`last()` Returns the leaf of current JSON Pointer expression.
`JsonPointer`	`matchElement(int index)`
`boolean`	`matches()`
`boolean`	`matchesElement(int index)` Method that may be called to see if the pointer would match array element (of a JSON Array) with given index.
`boolean`	`matchesProperty(java.lang.String name)` Method that may be called to see if the pointer would match property (of a JSON Object) with given name.
`JsonPointer`	`matchProperty(java.lang.String name)`
`boolean`	`mayMatchElement()`
`boolean`	`mayMatchProperty()`
`JsonPointer`	`tail()` Accessor for getting a "sub-pointer", instance where current segment has been removed and pointer includes rest of segments.
`java.lang.String`	`toString()`
`static JsonPointer`	`valueOf(java.lang.String input)` Alias for `compile(java.lang.String)`; added to make instances automatically deserializable by Jackson databind.

  - compile
```
public static JsonPointer compile(java.lang.String input)
                           throws java.lang.IllegalArgumentException
```
    Factory method that parses given input and construct matching pointer instance, if it represents a valid JSON Pointer: if not, a IllegalArgumentException is thrown.
    
    Throws:
    
    java.lang.IllegalArgumentException - Thrown if the input does not present a valid JSON Pointer expression: currently the only such expression is one that does NOT start with a slash ('/').
  - valueOf
```
public static JsonPointer valueOf(java.lang.String input)
```
    Alias for compile(java.lang.String); added to make instances automatically deserializable by Jackson databind.

```
public boolean mayMatchProperty()
```
  - mayMatchElement
```
public boolean mayMatchElement()
```
  - last
```
public JsonPointer last()
```
    Returns the leaf of current JSON Pointer expression. Leaf is the last non-null segment of current JSON Pointer.

  - append
```
public JsonPointer append(JsonPointer tail)
```
  - matchesProperty
```
public boolean matchesProperty(java.lang.String name)
```
    Method that may be called to see if the pointer would match property (of a JSON Object) with given name.
    
    Since:
    
    2.5
  - matchProperty
```
public JsonPointer matchProperty(java.lang.String name)
```
  - matchesElement
```
public boolean matchesElement(int index)
```
    Method that may be called to see if the pointer would match array element (of a JSON Array) with given index.
    
    Since:
    
    2.5
  - matchElement
```
public JsonPointer matchElement(int index)
```
    Since:
    
    2.6
  - tail
```
public JsonPointer tail()
```
    Accessor for getting a "sub-pointer", instance where current segment has been removed and pointer includes rest of segments. For matching state, will return null.
  - head
```
public JsonPointer head()
```
    Accessor for getting a pointer instance that is identical to this instance except that the last segment has been dropped. For example, for JSON Point "/root/branch/leaf", this method would return pointer "/root/branch" (compared to tail() that would return "/branch/leaf"). For leaf
