public interface Int2IntMap extends Int2IntFunction, java.util.Map<java.lang.Integer,java.lang.Integer>
Map
; 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()
and values()
.
Moreover, a number of methods, such as size()
,
defaultReturnValue()
, etc., are un-defaulted as their function
default do not make sense for a map. Maps returning entry sets of type
Int2IntMap.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 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.- Parameters:

- the function to compute a value.- Returns:

- the new value associated with the specified key, or the default return value if no value is associated with the key.
- Since:
- 8.0.0
- See Also:
Map.merge(Object, Object, java.util.function.BiFunction)
- API Notes:
- The JDK specification for this method equates not being associated with a value with being associated with {code null}. This is not the case for this method.
-
mergeInt
default int mergeInt(int key, int value, java.util.function.IntBinaryOperator 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.- 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.
- Since:
- 8.5.0
- See Also:
Map.merge(Object, Object, java.util.function.BiFunction)
- API Notes:
- The JDK specification for this method equates not being associated
with a value with being associated with {code null}. This is not the
case for this method. Moreover, this method cannot delete entries as
the type-specific remapping function cannot return
null
.
-
mergeInt
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.- 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.- Since:
- 8.5.1
- See Also:
Map.merge(Object, Object, java.util.function.BiFunction)
- API Notes:
- The JDK specification for this method equates not being associated
with a value with being associated with {code null}. This is not the
case for this method. Moreover, this method cannot delete entries as
the type-specific remapping function cannot return
null
.WARNING: Overriding this method is almost always a mistake, as this overload only exists to disambiguate. Instead, override the overload that uses the JDK's primitive binary operator (e.g.
IntBinaryOperator
).If Java supported final default methods, this would be one, but sadly it does not.
If you checked and are overriding the version with
java.util.function.XBinaryOperator
, and still see this warning, then your IDE is incorrectly conflating this method with the proper method to override, and you can safely ignore this message.
