CacheStorage

All Known Subinterfaces:

ConcurrentCacheStorage

All Known Implementing Classes:

MruCacheStorage, SoftCacheStorage, StrongCacheStorage
```
public interface CacheStorage
```
Cache storage abstracts away the storage aspects of a cache - associating an object with a key, retrieval and removal via the key. It is actually a small subset of the Map interface. The implementations can be coded in a non-threadsafe manner as the natural user of the cache storage, TemplateCache does the necessary synchronization.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`clear()`	Removes all values from this cache
`Object`	`get(Object key)`	Retrieve a cached value associated with a key
`void`	`put(Object key, Object value)`	Associates a key with a cached value
`void`	`remove(Object key)`	Removes the value associated with a key, if it exists.

- Method Detail
  - get
```
Object get(Object key)
```
    Retrieve a cached value associated with a key
    
    Parameters:
    
    key - the key for retrieving an associated value
    
    Returns:
    
    the cached value associated with the key, or null if no value is associated with the key.
  - put
```
void put(Object key,
         Object value)
```
    Associates a key with a cached value
    
    Parameters:
    
    key - the key to associate with a value
    
    value - the value associated with the key.
  - remove
```
void remove(Object key)
```
    Removes the value associated with a key, if it exists. If it doesn't exist, this method does nothing.
    
    Parameters:
    
    key - the key whose associated value is removed from the cache.
  - clear
```
void clear()
```
    Removes all values from this cache
