public interface Short2BooleanMap extends Short2BooleanFunction, Map<Short,Boolean>
A type-specificMap
; provides some additional methods that use polymorphism to avoid (un)boxing, and handling of a default return value.Besides extending the corresponding type-specific function, this interface strengthens
Map.entrySet()
,keySet()
andvalues()
. Moreover, a number of methods, such assize()
,defaultReturnValue()
, etc., are un-defaulted as their function default do not make sense for a map. Maps returning entry sets of typeShort2BooleanMap.FastEntrySet
support also fast iteration.A submap or subset may or may not have an independent default return value (which however must be initialized to the default return value of the originator).

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

- the function to compute a value.- Returns:
- the current (existing or computed) value associated with the specified key.

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

null
in the mapping function.- 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,

fastutil
'sFunction
. SinceFunction
has acontainsKey()
method, it is possible to avoid adding a key by havingcontainsKey()
returnfalse
for that key.- Parameters:

compute
default boolean compute(short key, BiFunction<? super Short,? super Boolean,? extends Boolean> remappingFunction)

if there is no current mapping).If the function returns
null

- 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.
- Since:

merge
default boolean merge(short key, boolean value, BiFunction<? super Boolean,? super Boolean,? extends Boolean> remappingFunction)
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
.- Parameters:

- 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
