public interface UESCache<K,V>

This component provides basic operations for common caching. Encapsulates different implementations of caching providers.

Method Summary

Methods

Modifier and Type	Method and Description
void	clear()
void	evict(K key)
V	get(K key) Returns the value to which the specified key is mapped, or null if this map contains no mapping for the key.
void	put(K key, V value) Associates the specified value with the specified key in this cache.

Method Detail

get

V get(K key)

Returns the value to which the specified key is mapped, or null if this map contains no mapping for the key.

More formally, if this cache contains a mapping from a key k to a value v such that (key==null ? k==null : key.equals(k)) , then this method returns v; otherwise it returns null. (There can be at most one such mapping.)

Parameters:

key - the key whose associated value is to be returned

Returns:

the value to which the specified key is mapped, or null if this cache contains no mapping for the key

Throws:

java.lang.NullPointerException - if the specified key is null and this map does not permit null keys (optional)

put

void put(K key,
V value)

Associates the specified value with the specified key in this cache. If the cache previously contained a mapping for the key, the old value is replaced by the specified value. (A cache m is said to contain a mapping for a key k if and only if m.containsKey(k) would return true.)

Parameters:

key - key with which the specified value is to be associated

value - value to be associated with the specified key

evict

void evict(K key)

clear

void clear()
