Modifier and Type | Method and Description |
---|---|
void |
clear()
Removes all associations from this function (optional operation).
|
boolean |
containsKey(long k) |
boolean |
containsKey(Object ok)
Returns true if this function contains a mapping for the specified key.
|
boolean |
containsValue(Object v) |
V |
defaultReturnValue()
Gets the default return value.
|
void |
defaultReturnValue(V defRetValue)
Sets the default return value.
|
ObjectSet<Map.Entry<Long,V>> |
entrySet()
Returns a set view of the mappings contained in this map.
|
V |
get(long k)
Returns the value to which the given key is mapped.
|
V |
get(Object k)
Delegates to the corresponding type-specific method, taking care of returning
null on a missing key. |
boolean |
isEmpty() |
LongSet |
keySet()
Returns a set view of the keys contained in this map.
|
ObjectSet<Long2ReferenceMap.Entry<V>> |
long2ReferenceEntrySet()
Returns a type-specific set view of the mappings contained in this map.
|
V |
put(long k,
V v)
Adds a pair to the map.
|
void |
putAll(Map<? extends Long,? extends V> m) |
V |
remove(long k)
Removes the mapping with the given key.
|
V |
remove(Object k)
Delegates to the corresponding type-specific method, taking care of returning
null on a missing key. |
int |
size()
Returns the intended number of keys in this function, or -1 if no such number exists.
|
String |
toString() |
ReferenceCollection<V> |
values()
Returns a set view of the values contained in this map.

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<Long2ReferenceMap.Entry<V>> long2ReferenceEntrySet()
Long2ReferenceMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Long2ReferenceMap.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.
