char2IntEntrySet
Description copied from interface:Char2IntMapReturns a type-specific set view of the mappings contained in this map.This method is necessary because there is no inheritance along type parameters: it is thus impossible to strengthen
Map.entrySet()so that it returns anObjectSetof type-specific entries (the latter makes it possible to access keys and values with type-specific methods).- Specified by:
char2IntEntrySetin interfaceChar2IntMap- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
entrySet
Deprecated.Please use the corresponding type-specific method instead.Returns a set view of the mappings contained in this map.Note that this specification strengthens the one given in
Map.entrySet().- Specified by:
entrySetin interfaceChar2IntMap- Specified by:
entrySetin interfaceMap<Character,Integer>- Returns:
- a set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
keySet
Description copied from interface:Char2IntMapNote that this specification strengthens the one given in
Map.keySet().- Specified by:
keySetin interfaceChar2IntMap- Specified by:
keySetin interfaceMap<Character,Integer>- Returns:
- a set view of the keys contained in this map.
- See Also:
Map.keySet()
-
values
Description copied from interface:Char2IntMapNote that this specification strengthens the one given in
Map.values().- Specified by:
valuesin interfaceChar2IntMap- Specified by:
