Modifier and Type | Method and Description |
---|---|
void |
clear()
Removes all associations from this function (optional operation).
|
boolean |
containsKey(double k) |
boolean |
containsKey(Object ok)
Returns true if this function contains a mapping for the specified key.
|
boolean |
containsValue(float v) |
boolean |
containsValue(Object ov) |
float |
defaultReturnValue()
Gets the default return value.
|
void |
defaultReturnValue(float defRetValue)
Sets the default return value.
|
ObjectSet<Double2FloatMap.Entry> |
double2FloatEntrySet()
Returns a type-specific set view of the mappings contained in this map.
|
ObjectSet<Map.Entry<Double,Float>> |
entrySet()
Returns a set view of the mappings contained in this map.
|
float |
get(double k)
Returns the value to which the given key is mapped.
|
boolean |
isEmpty() |

keySet()
Returns a set view of the keys contained in this map.
|
float |
put(double k,
float v)
Adds a pair to the map.
|

toString() |
FloatCollection |
values()
Returns a set view of the values 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<Double2FloatMap.Entry> double2FloatEntrySet()
Double2FloatMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Double2FloatMap.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.
