Class ConcurrentHashMap.SimpleEntry<K,V>

java.lang.Object
  java.util.concurrent.ConcurrentHashMap.SimpleEntry<K,V>

All Implemented Interfaces:

Map.Entry<K,V>

Enclosing class:

ConcurrentHashMap<K,V>

static final class ConcurrentHashMap.SimpleEntry<K,V>
extends Object
implements Map.Entry<K,V>

This duplicates java.util.AbstractMap.SimpleEntry until this class is made accessible.

Field Summary

(package private) K	key
(package private) V	value

Constructor Summary

ConcurrentHashMap.SimpleEntry(K key, V value)

ConcurrentHashMap.SimpleEntry(Map.Entry<K,V> e)

Method Summary

(package private) static boolean	eq(Object o1, Object o2)
boolean	equals(Object o) Compares the argument to the receiver, and returns true if they represent the same object using a class specific comparison.
K	getKey() Gets the key.
V	getValue() Gets the value.
int	hashCode() Returns an integer hash code for the receiver.
V	setValue(V value) Sets the value.
String	toString() Returns a string containing a concise, human-readable description of the receiver.

ConcurrentHashMap.SimpleEntry

public ConcurrentHashMap.SimpleEntry(Map.Entry<K,V> e)

Method Detail

getKey

public K getKey()

Description copied from interface: Map.Entry

Gets the key.

Specified by:

getKey in interface Map.Entry<K,V>

Returns:

the key

getValue

public V getValue()

Description copied from interface: Map.Entry

Gets the value.

Specified by:

getValue in interface Map.Entry<K,V>

Returns:

the value

setValue

public V setValue(V value)

Description copied from interface: Map.Entry

Sets the value.

Specified by:

setValue in interface Map.Entry<K,V>

Parameters:

value - the new value

Returns:

object

equals

public boolean equals(Object o)

Description copied from class: Object

Compares the argument to the receiver, and returns true if they represent the same object using a class specific comparison. The implementation in Object returns true only if the argument is the exact same object as the receiver (==).

Specified by:

equals in interface Map.Entry<K,V>

Overrides:

equals in class Object

Parameters:

o - Object the object to compare with this object.

Returns:

boolean true if the object is the same as this object false if it is different from this object.

Object.hashCode()

hashCode

public int hashCode()

Description copied from class: Object

Returns an integer hash code for the receiver. Any two objects which answer true when passed to .equals must answer the same value for this method.

Specified by:

hashCode in interface Map.Entry<K,V>

Overrides:

hashCode in class Object

Returns:

int the receiver's hash.

See Also:

Object.equals(java.lang.Object)

toString

public String toString()

Description copied from class: Object

Returns a string containing a concise, human-readable description of the receiver.

Overrides:

toString in class Object

Returns:

String a printable representation for the receiver.

eq

static boolean eq(Object o1,
                  Object o2)
