* Report whether the given key is found.

* Determine whether a key is in a mapping, and access its value.
|

*
|

* This method can only be called on mapping nodes.
|

*
|
||||
* Returns:
|

* A pointer to the value of the given key, or null if not found.
|
||||
* Params: key = Key to search for.
|
||||
*
|
||||
* Be careful! Modifying the mapping with any other function can
|
||||
* invalidate the pointer.
|

* Returns: A pointer to the value (as a Node) corresponding to key,
|
||||
* or null if not found.

*
|
||||
* Params: key = Key to search for.
|
||||
* Note: Any modification to the node can invalidate the returned
|

* pointer.
