reference2FloatEntrySet
Description copied from interface:Reference2FloatMapReturns 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 anObjectSetof type-specific entries (the latter makes it possible to access keys and values with type-specific methods).- Specified by:

- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()

Map.entrySet().- Specified by:

getOrDefault
Description copied from interface:Reference2FloatMapReturns the value to which the specified key is mapped, or thedefaultValueif this map contains no mapping for the key.- Specified by:
getOrDefaultin interfaceReference2FloatMap<K>- Parameters:
key- the key.defaultValue- the default mapping of the key.- Returns:

defaultValueif this map contains no mapping for the key. - See Also:

putIfAbsent
Description copied from interface:Reference2FloatMapIf the specified key is not already associated with a value, associates it with the given value and returns the default return value, else returns the current value.- Specified by:
putIfAbsentin interfaceReference2FloatMap<K>- Parameters:
key- key with which the specified value is to be associated.value- value to be associated with the specified key.- Returns:
- the previous value associated with the specified key, or the default return value if there was no mapping for the key.
- See Also:
Map.putIfAbsent(Object, Object)
-
remove
Description copied from interface:Reference2FloatMapRemoves the entry for the specified key only if it is currently mapped to the specified value.- Specified by:
removein interfaceReference2FloatMap<K>- Parameters:
key- key with which the specified value is associated.value- value expected to be associated with the specified key.- Returns:
trueif the value was removed.- See Also:
Map.remove(Object, Object)
-

Description copied from interface:Reference2FloatMapReplaces the entry for the specified key only if it is currently mapped to some value.- Specified by:
replacein interfaceReference2FloatMap<K>- Parameters:
key- key with which the specified value is associated.value- value to be associated with the specified key.- Returns:
- the previous value associated with the specified key, or the default return value if there was no mapping for the key.

computeFloatIfAbsent
Description copied from interface:Reference2FloatMapIf 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
mappingFunctioncannot returnnull. If such a behavior is needed, please use the corresponding nullable version.- Specified by:
computeFloatIfAbsentin interfaceReference2FloatMap<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)
-
computeFloatIfAbsentPartial
public float computeFloatIfAbsentPartial(K key, Reference2FloatFunction<? super K> mappingFunction)Description copied from interface:Reference2FloatMapIf 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. SinceFunctionhas acontainsKey()method, it is possible to avoid adding a key by havingcontainsKey()returnfalsefor that key.- Specified by:
computeFloatIfAbsentPartialin interfaceReference2FloatMap<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)
-
computeFloatIfPresent
public float computeFloatIfPresent(K key, BiFunction<? super K,? super Float,? extends Float> remappingFunction)Description copied from interface:Reference2FloatMapIf the value for the specified key is present, attempts to compute a new mapping given the key and its current mapped value.- Specified by:
computeFloatIfPresentin interfaceReference2FloatMap<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)
-
computeFloat
public float computeFloat(K key, BiFunction<? super K,? super Float,? extends Float> remappingFunction)Description copied from interface:Reference2FloatMapAttempts to compute a mapping for the specified key and its current mapped value (ornullif 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:
computeFloatin interfaceReference2FloatMap<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.

-
mergeFloat
public float mergeFloat(K key, float value, BiFunction<? super Float,? super Float,? extends Float> remappingFunction)Description copied from interface:Reference2FloatMapIf 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:
mergeFloatin interfaceReference2FloatMap<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.
