public class SoftValueHashMap extends AbstractMap implements Map
AbstractMap.SimpleEntry<K,V>, AbstractMap.SimpleImmutableEntry<K,V>| Constructor and Description |
|---|
SoftValueHashMap()
Constructs a new, empty
WeakHashMap with the default
initial capacity and the default load factor, which is 0.75. |
SoftValueHashMap(int initialCapacity)
Constructs a new, empty
WeakHashMap with the given initial
capacity and the default load factor, which is 0.75. |
SoftValueHashMap(int initialCapacity,
float loadFactor)
Constructs a new, empty
WeakHashMap with the given initial
capacity and the given load factor. |
SoftValueHashMap(Map t)
Constructs a new
WeakHashMap with the same mappings as the
specified Map. |
| Modifier and Type | Method and Description |
|---|---|
void |
clear()
Removes all mappings from this map.
|
boolean |
containsKey(Object key)
Returns
true if this map contains a mapping for the
specified key. |
Set |
entrySet()
Returns a set of the mappings contained in this hash table.
|
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. |
Object |
put(Object key,
Object value)
Updates this map so that the given
key maps to the given
value. |
Object |
remove(Object key)
Removes the mapping for the given
key from this map, if
present. |
int |
size()
Returns the number of key-value mappings in this map.

WeakHashMap with the default
initial capacity and the default load factor, which is 0.75.public SoftValueHashMap(Map t)
WeakHashMap with the same mappings as the
specified Map. The WeakHashMap is created with
an initial capacity of twice the number of mappings in the specified map
or 11 (whichever is greater), and a default load factor, which is
0.75.t - the map whose mappings are to be placed in this map.public Set entrySet()
