java.lang.Object java.util.AbstractMap<K,V> com.sun.jersey.core.util.KeyComparatorHashMap<K,V>
public class KeyComparatorHashMap<K,V>
A implementation similar to HashMap
but supports the
comparison of keys using a KeyComparator
.

KeyComparatorHashMap(int initialCapacity,
float loadFactor,
KeyComparator<K> keyComparator)
Constructs an empty HashMap with the specified initial capacity and load factor. |
|
KeyComparatorHashMap(int initialCapacity,
KeyComparator<K> keyComparator)
Constructs an empty HashMap with the specified initial capacity and the default load factor (0.75). |
|
KeyComparatorHashMap(KeyComparator<K> keyComparator)
Constructs an empty HashMap with the default initial capacity (16) and the default load factor (0.75). |
|
KeyComparatorHashMap(java.util.Map<? extends K,? extends V> m,
KeyComparator<K> keyComparator)
Constructs a new HashMap with the same mappings as the specified Map. |
Method Summary | |
---|---|
void |
clear()
Removes all mappings from this map. |
java.lang.Object |
clone()
Returns a shallow copy of this HashMap instance: the keys and values themselves are not cloned. |
boolean |
containsKey(java.lang.Object key)
Returns true if this map contains a mapping for the specified key. |
boolean |
containsValue(java.lang.Object value)
Returns true if this map maps one or more keys to the specified value. |
java.util.Set<java.util.Map.Entry<K,V>> |
entrySet()
Returns a collection view of the mappings contained in this map. |
V |
get(java.lang.Object key)
Returns the value to which the specified key is mapped in this identity hash map, or null if the map contains no mapping for this key. |
int |
getDEFAULT_INITIAL_CAPACITY()
|
int |
getModCount()
Get the number of times this HashMap has been structurally modified Structural modifications are those that change the number of mappings in the HashMap or otherwise modify its internal structure (e.g., rehash). |
boolean |
isEmpty()
Returns true if this map contains no key-value mappings. |
V |
put(K key,
V value)
Associates the specified value with the specified key in this map. |
void |
putAll(java.util.Map<? extends K,? extends V> m)
Copies all of the mappings from the specified map to this map These mappings will replace any mappings that this map had for any of the keys currently in the specified map. |
V |
remove(java.lang.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. |
