Beschreibung aus Schnittstelle kopiert: Int2IntMap

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.

 int value)

Beschreibung aus Schnittstelle kopiert: Int2IntMap

Type Specific method to reduce boxing/unboxing of values

addTo

public int addTo(int key,
 int value)

Beschreibung aus Schnittstelle kopiert: Int2IntMap

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

Parameter:

value - the value that should be inserted / added

Gibt zurück:

the last present value or default return value.

subFrom

public int subFrom(int key,
