Modifier and Type | Method and Description |
---|---|
void |
clear()
Removes all associations from this function (optional operation).

containsValue(short v) |
short |
defaultReturnValue()
Gets the default return value.
|
void |
defaultReturnValue(short defRetValue)
Sets the default return value.
|
ObjectSet<Map.Entry<Short,Short>> |

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<Short2ShortMap.Entry> short2ShortEntrySet()
Short2ShortMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Short2ShortMap.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.
