computeIfAbsent
public int computeIfAbsent(short key, IntUnaryOperator mappingFunction)
Description copied from interface:Short2IntMap
If the specified key is not already associated with a value, attempts to compute its value using the given mapping function and enters it into this map.Note that contrarily to the default computeIfAbsent(), it is not possible to not add a value for a given key, since the
mappingFunction
cannot returnnull
. If such a behavior is needed, please use the corresponding nullable version.- Specified by:
computeIfAbsent
in interfaceShort2IntMap
- Parameters:
key
- key with which the specified value is to be associated.mappingFunction
- the function to compute a value.- Returns:
- the current (existing or computed) value associated with the specified key.
- See Also:
Map.computeIfAbsent(Object, java.util.function.Function)
-
computeIfAbsentNullable
public int computeIfAbsentNullable(short key, IntFunction<? extends Integer> mappingFunction)
Description copied from interface:Short2IntMap
If the specified key is not already associated with a value, attempts to compute its value using the given mapping function and enters it into this map unless it isnull
.Note that this version of computeIfAbsent() should be used only if you plan to return
null
in the mapping function.- Specified by:
computeIfAbsentNullable
in interfaceShort2IntMap
- Parameters:
key
- key with which the specified value is to be associated.mappingFunction
- the function to compute a value.- Returns:
- the current (existing or computed) value associated with the specified key,

computeIfAbsentPartial
public int computeIfAbsentPartial(short key, Short2IntFunction mappingFunction)
Description copied from interface:Short2IntMap
If the specified key is not already associated with a value, attempts to compute its value using the given mapping function and enters it into this map, unless the key is not present in the given mapping function.This version of computeIfAbsent() uses a type-specific version of
fastutil
'sFunction
. SinceFunction
has acontainsKey()
method, it is possible to avoid adding a key by havingcontainsKey()
returnfalse
for that key.- Specified by:
computeIfAbsentPartial
in interfaceShort2IntMap

key
- key with which the specified value is to be associated.mappingFunction
- the function to compute a value.- Returns:

computeIfPresent
in interfaceShort2IntMap
- Parameters:
key
- key with which the specified value is to be associated.remappingFunction
- the function to compute a value.- Returns:
- the new value associated with the specified key, or the default return value if none.

Attempts to compute a mapping for the specified key and its current mapped value (ornull
if there is no current mapping).If the function returns
null
, the mapping is removed (or remains absent if initially absent). If the function itself throws an (unchecked) exception, the exception is rethrown, and the current mapping is left unchanged.- Specified by:
compute
in interfaceShort2IntMap
- Parameters:
key
- key with which the specified value is to be associated.remappingFunction
- the function to compute a value.- Returns:
- the new value associated with the specified key, or the default return value if none.

merge
public int merge(short key, int value, BiFunction<? super Integer,? super Integer,? extends Integer> remappingFunction)

key
- key with which the resulting value is to be associated.value
- the value to be merged with the existing value associated with the key or, if no existing value is associated with the key, to be associated with the key.remappingFunction
