Interface Cache.Entry<K,V>

Enclosing interface:

Cache<K,V>

public static interface Cache.Entry<K,V>

A cache entry (key-value pair).

Method Summary

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 stored in the cache when this entry was created.
int	hashCode() Returns the hash code value for this cache entry.

Method Detail

getKey

K getKey()

Returns the key corresponding to this entry.

Returns:

the key corresponding to this entry

getValue

V getValue()

Returns the value stored in the cache when this entry was created.

Returns:

the value corresponding to this entry

equals

boolean equals(Object o)

Compares the specified object with this entry for equality. Returns 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().equals(e2.getKey())  &&
     e1.getValue().equals(e2.getValue())
 

This ensures that the equals method works properly across different implementations of the Cache.Entry interface.

Overrides:

equals in class Object

Parameters:

o - object to be compared for equality with this cache entry

Returns:

true if the specified object is equal to this cache entry

hashCode

int hashCode()

Returns the hash code value for this cache entry. The hash code of a cache entry e is defined to be:

     e.getKey().hashCode() ^
     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.

Overrides:

hashCode in class Object

Returns:

the hash code value for this cache entry
