Method Detail

containsValue
public boolean containsValue(int v)
Description copied from interface:Short2IntMap
Returnstrue
if this map maps one or more keys to the specified value.- Specified by:
containsValue
in interfaceShort2IntMap
- See Also:
Map.containsValue(Object)
-
getOrDefault
@Deprecated public java.lang.Integer getOrDefault(java.lang.Object key, java.lang.Integer defaultValue)
Deprecated.Description copied from interface:Short2IntMap
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<java.lang.Short,java.lang.Integer>
- Specified by:
getOrDefault
in interfacejava.util.Map<java.lang.Short,java.lang.Integer>
- Specified by:
getOrDefault
in interfaceShort2IntFunction
- Specified by:
getOrDefault
in interfaceShort2IntMap
- 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 int getOrDefault(short key, int defaultValue)
Description copied from interface:Short2IntFunction
Returns the value associated by this function to the specified key, or give the specified value if not present.- Specified by:
getOrDefault
in interfaceShort2IntFunction
- Specified by:
getOrDefault
in interfaceShort2IntMap
- Overrides:
getOrDefault
in classShort2IntFunctions.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 interfacejava.util.Map<java.lang.Short,java.lang.Integer>
- Specified by:
containsValue
in interfaceShort2IntMap
-
putAll
public void putAll(java.util.Map<? extends java.lang.Short,? extends java.lang.Integer> m)
- Specified by:
putAll
in interfacejava.util.Map<java.lang.Short,java.lang.Integer>
-
short2IntEntrySet
public ObjectSet<Short2IntMap.Entry> short2IntEntrySet()
Description copied from interface:Short2IntMap
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:
short2IntEntrySet
in interfaceShort2IntMap
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
keySet
public ShortSet keySet()
Description copied from interface:Short2IntMap
- Specified by:
keySet
in interfacejava.util.Map<java.lang.Short,java.lang.Integer>
- Specified by:
keySet
in interfaceShort2IntMap
- Returns:
- a set view of the keys contained in this map.
- See Also:
Map.keySet()
-
values
public IntCollection values()
Description copied from interface:Short2IntMap
- Specified by:
values
in interfacejava.util.Map<java.lang.Short,java.lang.Integer>
- Specified by:
values
in interfaceShort2IntMap
- 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.Short,? super java.lang.Integer> consumer)
- Specified by:
forEach
in interfacejava.util.Map<java.lang.Short,java.lang.Integer>
- Specified by:
forEach
in interfaceShort2IntMap
-

in classShort2IntFunctions.EmptyFunction
-
isEmpty
public boolean isEmpty()
- Specified by:
isEmpty
in interfacejava.util.Map<java.lang.Short,java.lang.Integer>
-
hashCode
public int hashCode()
- Specified by:
hashCode
in interfacejava.util.Map<java.lang.Short,java.lang.Integer>
- Overrides:
