in interfacejava.util.Map<java.lang.Short,V>

short2ReferenceEntrySet
public ObjectSet<Short2ReferenceMap.Entry<V>> short2ReferenceEntrySet()
Description copied from interface:Short2ReferenceMap
Returns 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 anObjectSet
of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).- Specified by:
short2ReferenceEntrySet
in interfaceShort2ReferenceMap<V>
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
entrySet
@Deprecated public ObjectSet<java.util.Map.Entry<java.lang.Short,V>> entrySet()
Deprecated.Please use the corresponding type-specific method instead.Returns a set view of the mappings contained in this map.- Specified by:
entrySet
in interfacejava.util.Map<java.lang.Short,V>
- Specified by:
entrySet
in interfaceShort2ReferenceMap<V>
- Returns:
- a set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
keySet
public ShortSet keySet()
Description copied from interface:Short2ReferenceMap
- Specified by:
keySet
in interfacejava.util.Map<java.lang.Short,V>
- Specified by:
keySet
in interfaceShort2ReferenceMap<V>
- Returns:
- a set view of the keys contained in this map.
