Beschreibung aus Schnittstelle kopiert: Int2LongMap

Type Specific method to reduce boxing/unboxing of values

Parameter:

key - the key that should be inserted,

value - the value that should be inserted

Gibt zurück:

the last present value or default return value.

• Map.put(Object, Object)

putIfAbsent

public long putIfAbsent(int key,
 long value)

Beschreibung aus Schnittstelle kopiert: Int2LongMap

Type Specific method to reduce boxing/unboxing of values

Parameter:

key - the key that should be inserted,

addTo

public long addTo(int key,
 long value)

Beschreibung aus Schnittstelle kopiert: Int2LongMap

A Helper method to add a primitives together. If key is not present then this functions as a put.

Parameter:

key - the key that should be inserted,

Gibt zurück:

the last present value or default return value.

subFrom

public long subFrom(int key,
