byte2LongEntrySet
Description copied from interface:Byte2LongMap
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
Map.entrySet()
so that it returns anObjectSet
of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).- Specified by:
byte2LongEntrySet
in interfaceByte2LongMap
- Returns:
- a type-specific set view of the mappings contained in this map.

putIfAbsent
public long putIfAbsent(byte key, long value) Description copied from interface:Byte2LongMap
If 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:

in interfaceByte2LongMap
- 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.

true
if the value was removed.- See Also:

replace
public long replace(byte key, long value) Description copied from interface:Byte2LongMap
Replaces the entry for the specified key only if it is currently mapped to some value.- Specified by:
replace
in interfaceByte2LongMap
- 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.

computeIfAbsent
Description copied from interface:Byte2LongMap
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 interfaceByte2LongMap
- 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:
-
computeIfAbsentNullable
Description copied from interface:Byte2LongMap
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 interfaceByte2LongMap
- 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, or the
default return value if the computed value is
null
. - See Also:
-
computeIfAbsent
Description copied from interface:Byte2LongMap
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:
computeIfAbsent
in interfaceByte2LongMap
- 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:
-

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 interfaceByte2LongMap
- 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:
-
compute
public long compute(byte key, BiFunction<? super Byte, ? super Long, ? extends Long> remappingFunction) Description copied from interface:Byte2LongMap
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 interfaceByte2LongMap
- 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.

merge
public long merge(byte key, long value, BiFunction<? super Long, ? super Long, ? extends Long> remappingFunction) Description copied from interface:Byte2LongMap
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:
merge
in interfaceByte2LongMap
- 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.
