The key class has to inherit Comparable. The value class can be any inherit of Object.
The inserted objects are owned by the Map by default, and are thus destroyed along with it, or during various replacement methods. By giving the MAP_REF flag to the constructor causes the objects not to be owned by the Map.
Map<String,String> has a shorthand macro StringMap. Many Map-handling functions, especially for StringMaps, are not included in the template, but are global. Such methods include toString(), splitpairs(), and joinpairs(). See section "globals" for more information, or the header mmap.h.
Maps can be iterated using MapIter. Note also the forMap and forStringMap macros in mmap.h

Implementation for Object.
|
|
|
Destroys all the items from the Map.
|
|
|
Same as failByThrow(false), but applies to only one access call. Giving parameter 'false' to this method cancels a previously given failByNullOnce(true) currently in effect. |
|
|
Should the access-methods of Map report missing elements by throwing an exception (true) or by returning a null reference (false, which is the default). Null references to objects can be checked by the global isnull() function. |

Returns a const reference to object associated to the key. For information about error handling and exceptions, see failByThrowOnce().

Returns the GenHash of the Map.

Returns a const pointer to object associated to the key, or NULL if the object was not found.

Returns a non-const reference to object associated to the key. For information about error handling and exceptions, see failByThrowOnce().
