Modifier and Type | Method and Description |
---|---|
void |
clear()
Removes all associations from this function (optional operation).
|
boolean |
containsKey(Object ok)
Returns true if this function contains a mapping for the specified key.
|
boolean |
containsKey(short k) |
boolean |
containsValue(long v) |
boolean |
containsValue(Object ov) |
long |
defaultReturnValue()
Gets the default return value.
|
void |
defaultReturnValue(long defRetValue)
Sets the default return value.
|
ObjectSet<Map.Entry<Short,Long>> |
entrySet()
Returns a set view of the mappings contained in this map.
|

Function
Most function implementations will have some knowledge of the intended number of keys in their domain. In some cases, however, this might not be possible.

public ObjectSet<Short2LongMap.Entry> short2LongEntrySet()
Short2LongMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Short2LongMap.entrySet()
so that it returns an ObjectSet
of objects of type Map.Entry
(the latter makes it possible to
access keys and values with type-specific methods).

This method must check whether the provided key is in the map using containsKey()
. Thus,
it probes the map twice. Implementors of subclasses should override it with a more efficient method.
