Method Detail

containsValue
public boolean containsValue(byte v)
Description copied from interface:Byte2ByteMap
Returnstrue
if this map maps one or more keys to the specified value.- Specified by:
containsValue
in interfaceByte2ByteMap
- See Also:
Map.containsValue(Object)
-
getOrDefault
@Deprecated public java.lang.Byte getOrDefault(java.lang.Object key, java.lang.Byte defaultValue)
Deprecated.Description copied from interface:Byte2ByteMap
Returns the value associated by this function to the specified key, or give the specified value if not present.This default implementation just delegates to the corresponding
Map
method.- Specified by:
getOrDefault
in interfaceByte2ByteFunction
- Specified by:
getOrDefault
in interfaceByte2ByteMap
- Specified by:
getOrDefault
in interfaceFunction<java.lang.Byte,java.lang.Byte>
- Specified by:
getOrDefault
in interfacejava.util.Map<java.lang.Byte,java.lang.Byte>
- Parameters:
key
- the key.defaultValue
- the default value to return if not present.- Returns:
- the corresponding value, or
defaultValue
if no value was present for the given key. - See Also:
Map.getOrDefault(Object, Object)
-
getOrDefault
public byte getOrDefault(byte key, byte defaultValue)
Description copied from interface:Byte2ByteFunction
Returns the value associated by this function to the specified key, or give the specified value if not present.- Specified by:
getOrDefault
in interfaceByte2ByteFunction
- Specified by:
getOrDefault
in interfaceByte2ByteMap
- Overrides:
getOrDefault
in classByte2ByteFunctions.EmptyFunction
- Parameters:
key
- the key.defaultValue
- the value to return if not present.- Returns:
- the corresponding value, or
defaultValue
if no value was present for the given key. - See Also:
Function.getOrDefault(Object, Object)
-
containsValue
@Deprecated public boolean containsValue(java.lang.Object ov)
Deprecated.Please use the corresponding type-specific method instead.- Specified by:
containsValue
in interfaceByte2ByteMap
- Specified by:
containsValue
in interfacejava.util.Map<java.lang.Byte,java.lang.Byte>
-
putAll
public void putAll(java.util.Map<? extends java.lang.Byte,? extends java.lang.Byte> m)
- Specified by:
putAll
in interfacejava.util.Map<java.lang.Byte,java.lang.Byte>
-
byte2ByteEntrySet
public ObjectSet<Byte2ByteMap.Entry> byte2ByteEntrySet()
Description copied from interface:Byte2ByteMap
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:
byte2ByteEntrySet
in interfaceByte2ByteMap
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
keySet
public ByteSet keySet()
Description copied from interface:Byte2ByteMap
- Specified by:
keySet
in interfaceByte2ByteMap
- Specified by:
keySet
in interfacejava.util.Map<java.lang.Byte,java.lang.Byte>
- Returns:
- a set view of the keys contained in this map.
- See Also:
Map.keySet()
-
values
public ByteCollection values()
Description copied from interface:Byte2ByteMap
- Specified by:
values
in interfaceByte2ByteMap
- Specified by:
values
in interfacejava.util.Map<java.lang.Byte,java.lang.Byte>
- Returns:
- a set view of the values contained in this map.
- See Also:
Map.values()
-
forEach
public void forEach(java.util.function.BiConsumer<? super java.lang.Byte,? super java.lang.Byte> consumer)
- Specified by:
forEach
in interfaceByte2ByteMap
- Specified by:
