public JsonValue add(Object object)
```
    Adds the specified value to the end of the list. This method is equivalent to the following code:
```
 add(size(), object);
 
```
    Parameters:
    
    object - the java object to add.
    
    Returns:
    
    this JSON value.
    
    Throws:
    
    JsonValueException - if this JSON value is not a List.
  - add
```
public JsonValue add(String key,
                     Object object)
```
    Adds the specified value.

    Parameters:
    
    key - the Map key or List index to add.
    
    object - the Java object to add.
    
    Returns:
    
    this JSON value.
    
    Throws:
    
    JsonValueException - if not a Map or List, the Map key already exists, or the List index is out of range.
  - addPermissive
```
public JsonValue addPermissive(JsonPointer pointer,
                               Object object)
```
    Adds the value identified by the specified pointer, relative to this value as root. Missing parent objects or lists will be created on demand.
    NOTE: values may be added to a list using the reserved JSON pointer token "-". For example, the pointer "/a/b/-" will add a new element to the list referenced by "/a/b".
    
    Parameters:
    
    pointer - identifies the child value to add.
    
    object - the Java object value to add.

public JsonValue clone()
```
    Returns a shallow copy of this JSON value. If this JSON value contains a Map or a List object, the returned JSON value will contain a shallow copy of the original contained object.
    The new value's members can be modified without affecting the original value. Modifying the member's members will almost certainly affect the original value. To avoid this, use the JsonValue.copy() method to return a deep copy of the JSON value.
    This method does not traverse the value's members, nor will it apply any transformations.

    index - the List index identifying the child value to remove.
  - remove
```
public void remove(JsonPointer pointer)
```
    Removes the specified child value with a pointer, relative to this value as root. If the specified child value is not defined, calling this method has no effect.

    pointer - the JSON pointer identifying the child value to remove.
  - remove
```
public void remove(String key)
```
    Removes the specified child value. If the specified child value is not defined, calling this method has no effect.

public boolean isEqualTo(JsonValue other)
```
    Performs a deep comparison of this JSON value with another JSON value, and returns whether the two objects are identical. Fails fast in that a false is returned as soon as a difference is detected.
    Note: Only values recognisable as JSON primitives (Map, List, Number, Boolean, String and null) are supported.
    
    Parameters:
    
    other - another value.
    
    Returns:
    
    whether the two objects are equal.
    
    Throws:
    
    NullPointerException - if other is null.
    
    IllegalArgumentException - if this or the other value contains non-JSON primitive values.
  - diff
```
public JsonValue diff(JsonValue target)
```
    Performs a deep comparison of this JSON vlaue with another JSON value, and produces a JSON Patch value, which contains the operations necessary to modify the current value to arrive at the target value.
    
    Parameters:
    
    target - the intended target value.
    
    Returns:
    
    the resulting JSON Patch value.

    NullPointerException - if either of original or target are null.
  - patch
```
public void patch(JsonValue patch)
```
    Applies a set of modifications in a JSON patch value to the current object, resulting in the intended target value. In the event of a failure, this method does not revert any modifications applied up to the point of failure.
    
    Parameters:
    
    patch - the JSON Patch value, specifying the modifications to apply to the original value.
    
    Throws:
    
    JsonValueException - if application of the patch failed.
  - merge
```
public JsonValue merge(JsonValue other)
```
    Creates a new JSON value which combines the contents this JSON value with another.
    If there are any matching pointers in the two JSON values, then the value in other overrides the value in this.
    
    Parameters:
    
    other - Another JSON value which should be merged with this one.
    
    Returns:
    
    a new JSON value which combines the contents of this JSON value and other.
