public static class AbstractMap.SimpleImmutableEntry<K,V> extends Object implements Map.Entry<K,V>, Serializable
| Constructor and Description |
|---|
SimpleImmutableEntry(K key,
V value)
Creates an entry representing a mapping from the specified
key to the specified value.
|
SimpleImmutableEntry(Map.Entry<? extends K,? extends V> entry)
Creates an entry representing the same mapping as the
specified entry.
|
| Modifier and Type | Method and Description |
|---|---|
boolean |
equals(Object o)
Compares the specified object with this entry for equality.
|
K |
getKey()
Returns the key corresponding to this entry.
|
V |
getValue()
Returns the value corresponding to this entry.
|
int |
hashCode()
Returns the hash code value for this map entry.
|
V |
setValue(V value)
Replaces the value corresponding to this entry with the specified
value (optional operation).
|
String |
toString()
Returns a String representation of this map entry.

public V setValue(V value)
setValue in interface Map.Entry<K,V>value - new value to be stored in this entryUnsupportedOperationException - alwayspublic boolean equals(Object o)
true if the given object is also a map entry and
the two entries represent the same mapping. More formally, two
entries e1 and e2 represent the same mapping
if
(e1.getKey()==null ?
e2.getKey()==null :
e1.getKey().equals(e2.getKey()))
&&
(e1.getValue()==null ?
e2.getValue()==null :
e1.getValue().equals(e2.getValue()))
This ensures that the equals method works properly across
different implementations of the Map.Entry interface.public int hashCode()
e is defined to be: (e.getKey()==null ? 0 : e.getKey().hashCode()) ^ (e.getValue()==null ? 0 : e.getValue().hashCode())This ensures that
e1.equals(e2) implies that
e1.hashCode()==e2.hashCode() for any two Entries
e1 and e2, as required by the general
contract of Object.hashCode().public String toString()
