Method Details
-
containsValue
public boolean containsValue(long v)Description copied from interface:Short2LongMap
Returnstrue
if this map maps one or more keys to the specified value.- Specified by:
containsValue
in interfaceShort2LongMap
- See Also:
Map.containsValue(Object)
-
getOrDefault
Deprecated.Description copied from interface:Short2LongMap
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 interfaceFunction<Short,Long>
- Specified by:
getOrDefault
in interfaceMap<Short,Long>
- Specified by:
getOrDefault
in interfaceShort2LongFunction
- Specified by:
getOrDefault
in interfaceShort2LongMap
- 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 long getOrDefault(short key, long defaultValue)Description copied from interface:Short2LongFunction
Returns the value associated by this function to the specified key, or give the specified value if not present.- Specified by:
getOrDefault
in interfaceShort2LongFunction
- Specified by:
getOrDefault
in interfaceShort2LongMap
- Overrides:
getOrDefault
in classShort2LongFunctions.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.Please use the corresponding type-specific method instead.- Specified by:
containsValue
in interfaceMap<Short,Long>
- Specified by:
containsValue
in interfaceShort2LongMap
-
putAll
-
short2LongEntrySet
Description copied from interface:Short2LongMap
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:
short2LongEntrySet
in interfaceShort2LongMap
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
keySet
Description copied from interface:Short2LongMap
- Specified by:
keySet
in interfaceMap<Short,Long>
- Specified by:
keySet
in interfaceShort2LongMap
- Returns:
- a set view of the keys contained in this map.
- See Also:
Map.keySet()
-
values
Description copied from interface:Short2LongMap
- Specified by:
values
in interfaceMap<Short,Long>
- Specified by:
values
in interfaceShort2LongMap
- Returns:
- a set view of the values contained in this map.

forEach

clone
- Overrides:
