| Inner classes inherited from class java.util.Map |
Map.Entry |
| Constructor Summary | |
IdentityHashMap()
Constructs a new, empty map with a default capacity and load factor, which is 0.75. |
|
IdentityHashMap(int initialCapacity)
Constructs a new, empty map with the specified initial capacity and default load factor, which is 0.75. |
|
IdentityHashMap(int initialCapacity,
float loadFactor)
Constructs a new, empty map with the specified initial capacity and the specified load factor. |
|
IdentityHashMap(Map t)
Constructs a new map with the same mappings as the given map. |
|
| Method Summary | |
void |
clear()
Removes all mappings from this map. |
Object |
clone()
Returns a shallow copy of this IdentityHashMap instance: the keys and values themselves are not cloned. |
boolean |
containsKey(Object key)
Returns true if this map contains a mapping for the specified key. |
boolean |
containsValue(Object value)
Returns true if this map maps one or more keys to the specified value. |
Set |
entrySet()
Returns a collection view of the mappings contained in this map. |
Object |
get(Object key)
Returns the value to which this map maps the specified key. |
boolean |
isEmpty()
Returns true if this map contains no key-value mappings. |
Set |
keySet()
Returns a set view of the keys contained in this map. |
Object |
put(Object key,
Object value)
Associates the specified value with the specified key in this map. |
void |
putAll(Map t)
Copies all of the mappings from the specified map to this one. |
Object |
remove(Object key)
Removes the mapping for this key from this map if present. |
int |
size()
Returns the number of key-value mappings in this map. |
Collection |
values()
Returns a collection view of the values contained in this map. |
