computeIfAbsent
public long computeIfAbsent(short key, IntToLongFunction mappingFunction)
Description copied from interface:Short2LongMap
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 interfaceShort2LongMap
- 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 long computeIfAbsentNullable(short key, IntFunction<? extends Long> mappingFunction)
Description copied from interface:Short2LongMap
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 interfaceShort2LongMap
- 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,
or the default return value if the computed value is
null
. - See Also:
Map.computeIfAbsent(Object, java.util.function.Function)
-
computeIfAbsentPartial
public long computeIfAbsentPartial(short key, Short2LongFunction mappingFunction)
Description copied from interface:Short2LongMap
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 interfaceShort2LongMap
- Parameters:
key
- key with which the specified value is to be associated.mappingFunction
- the function to compute a value.- Returns:

Description copied from interface:Short2LongMap
If the value for the specified key is present, attempts to compute a new mapping given the key and its current mapped value.- Specified by:
computeIfPresent
in interfaceShort2LongMap
- 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.

compute
public long compute(short key, BiFunction<? super Short,? super Long,? extends Long> remappingFunction)
Description copied from interface:Short2LongMap
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 interfaceShort2LongMap
- 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 long merge(short key, long value, BiFunction<? super Long,? super Long,? extends Long> remappingFunction)
Description copied from interface:Short2LongMap
If the specified key is not already associated with a value, associates it with the givenvalue
. Otherwise, replaces the associated value with the results of the given remapping function, or removes if the result isnull
.- Specified by:
merge
in interfaceShort2LongMap
- Parameters:
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
- the function to recompute a value if present.- Returns:
- the new value associated with the specified key, or the default return value if no value is associated with the key.
