void |
clear()
Removes all associations from this function (optional operation).
|

containsValue(double v) |
boolean |
containsValue(Object ov) |
double |
defaultReturnValue()
Gets the default return value.
|
void |
defaultReturnValue(double defRetValue)
Sets the default return value.
|
ObjectSet<Map.Entry<Float,Double>> |
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<Float2DoubleMap.Entry> float2DoubleEntrySet()
Float2DoubleMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Float2DoubleMap.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.
