Method Detail

containsValue
public boolean containsValue(byte v)
Description copied from interface:Char2ByteMap
Returnstrue
if this map maps one or more keys to the specified value.- Specified by:
containsValue
in interfaceChar2ByteMap
- See Also:
Map.containsValue(Object)
-
containsValue
@Deprecated public boolean containsValue(Object ov)
Deprecated.Please use the corresponding type-specific method instead.- Specified by:
containsValue
in interfaceChar2ByteMap
- Specified by:
containsValue
in interfaceMap<Character,Byte>
-
char2ByteEntrySet
public ObjectSet<Char2ByteMap.Entry> char2ByteEntrySet()
Description copied from interface:Char2ByteMap
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:
char2ByteEntrySet
in interfaceChar2ByteMap
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
entrySet
@Deprecated public ObjectSet<Map.Entry<Character,Byte>> 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:
entrySet
in interfaceChar2ByteMap
- Specified by:
entrySet
in interfaceMap<Character,Byte>
- Returns:
- a set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
keySet
public CharSet keySet()
Description copied from interface:Char2ByteMap
Note that this specification strengthens the one given in
Map.keySet()
.- Specified by:
keySet
in interfaceChar2ByteMap
- Specified by:
keySet
in interfaceMap<Character,Byte>
- Returns:
- a set view of the keys contained in this map.
- See Also:
Map.keySet()
-
values
public ByteCollection values()
Description copied from interface:Char2ByteMap
Note that this specification strengthens the one given in
Map.values()
.- Specified by:
values
in interfaceChar2ByteMap
- Specified by:
values
in interfaceMap<Character,Byte>
- Returns:
- a set view of the values contained in this map.
- See Also:
Map.values()
-
hashCode
public int hashCode()
-
equals
public boolean equals(Object o)
