byte2ReferenceEntrySet
public ObjectSet<Byte2ReferenceMap.Entry<V>> byte2ReferenceEntrySet()
Description copied from interface:Byte2ReferenceMap
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

computeIfAbsent
public V computeIfAbsent(byte key, IntFunction<? extends V> mappingFunction)
Description copied from interface:Byte2ReferenceMap
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 interfaceByte2ReferenceMap<V>
- 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)
-
computeIfAbsentPartial
public V computeIfAbsentPartial(byte key, Byte2ReferenceFunction<? extends V> mappingFunction)
Description copied from interface:Byte2ReferenceMap
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 interfaceByte2ReferenceMap<V>
- 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)
-
computeIfPresent
public V computeIfPresent(byte key, BiFunction<? super Byte,? super V,? extends V> remappingFunction)
Description copied from interface:Byte2ReferenceMap
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 interfaceByte2ReferenceMap<V>
- 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)
-
compute
public V compute(byte key, BiFunction<? super Byte,? super V,? extends V> remappingFunction)
Description copied from interface:Byte2ReferenceMap
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 interfaceByte2ReferenceMap<V>
- 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.

Map.compute(Object, java.util.function.BiFunction)
-
merge
public V merge(byte key, V value, BiFunction<? super V,? super V,? extends V> remappingFunction)
Description copied from interface:Byte2ReferenceMap
If the specified key is not already associated with a value or is associated with null, associates it with the given non-nullvalue
. Otherwise, replaces the associated value with the results of the given remapping function, or removes if the result isnull
.- Specified by:
merge
in interfaceByte2ReferenceMap<V>
- Parameters:
key
- key with which the resulting value is to be associated.value
- the non-null
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.
