GetNextAssoc	Gets the next element for iterating.
PGetNextAssoc	Gets a pointer to the next element for iterating.
GetStartPosition	Returns the position of the first element.
PGetFirstAssoc	Returns a pointer to the first element.
InitHashTable	Initializes the hash table and specifies its size.
Lookup	Looks up the value mapped to a given key.
PLookup	Returns a pointer to a key whose value matches the specified value.
operator []	Inserts an element into the map — operator substitution for SetAt.
RemoveAll	Removes all the elements from this map.
RemoveKey	Removes an element specified by a key.
SetAt	Inserts an element into the map; replaces an existing element if a matching key is found.

Status

GetCount	Returns the number of elements in this map.
