public char computeIfAbsent(byte key, java.util.function.IntUnaryOperator mappingFunction)
Description copied from interface:Byte2CharMap
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 interfaceByte2CharMap
- 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)
-

Description copied from interface:Byte2CharMap
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 interfaceByte2CharMap
- 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,

-
computeIfAbsentPartial
public char computeIfAbsentPartial(byte key, Byte2CharFunction mappingFunction)
Description copied from interface:Byte2CharMap
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 interfaceByte2CharMap

key
- key with which the specified value is to be associated.mappingFunction
- the function to compute a value.- Returns:

in interfaceByte2CharMap
- Parameters:

- key with which the specified value is to be associated.remappingFunction
- the function to compute a value.- Returns:

Description copied from interface:Byte2CharMap
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 interfaceByte2CharMap
- 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.

key
- key with which the resulting value is to be associated.value
