computeDoubleIfAbsent
public double computeDoubleIfAbsent(K key, ToDoubleFunction<? super K> mappingFunction)
Description copied from interface:Object2DoubleMap
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:
computeDoubleIfAbsent
in interfaceObject2DoubleMap<K>
- 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)
-
computeDoubleIfAbsentPartial
public double computeDoubleIfAbsentPartial(K key, Object2DoubleFunction<? super K> mappingFunction)
Description copied from interface:Object2DoubleMap
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:
computeDoubleIfAbsentPartial
in interfaceObject2DoubleMap<K>
- 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)
-
computeDoubleIfPresent
public double computeDoubleIfPresent(K key, BiFunction<? super K,? super Double,? extends Double> remappingFunction)
Description copied from interface:Object2DoubleMap
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:
computeDoubleIfPresent
in interfaceObject2DoubleMap<K>
- 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.
- See Also:
Map.computeIfPresent(Object, java.util.function.BiFunction)
-
computeDouble
public double computeDouble(K key, BiFunction<? super K,? super Double,? extends Double> remappingFunction)
Description copied from interface:Object2DoubleMap
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:
computeDouble
in interfaceObject2DoubleMap<K>
- 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.

-
mergeDouble
public double mergeDouble(K key, double value, BiFunction<? super Double,? super Double,? extends Double> remappingFunction)
Description copied from interface:Object2DoubleMap
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:
mergeDouble
in interfaceObject2DoubleMap<K>
- 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.
