```
public MapCacheStore(Map<K,V> map)
```
    Create a CacheStore that delegates to a Map.
    
    Parameters:
    
    map - the Map to use as the underlying store for this CacheStore
- Method Detail
  - load
```
public V load(K key)
```
    Return the value associated with the specified key, or null if the key does not have an associated value in the underlying store.
    
    Specified by:
    
    load in interface CacheLoader<K,V>
    
    Specified by:
    
    load in class AbstractCacheLoader<K,V>
    
    Parameters:
    
    key - key whose associated value is to be returned
    
    Returns:
    
    the value associated with the specified key, or null if no value is available for that key
  - store
```
public void store(K key,
                  V value)
```
    Store the specified value under the specified key in the underlying store. This method is intended to support both key/value creation and value update for a specific key.
    
    Specified by:
    
    store in interface CacheStore<K,V>
    
    Overrides:
    
    store in class AbstractCacheStore<K,V>
    
    Parameters:
    
    key - key to store the value under
    
    value - value to be stored
  - storeAll
```
public void storeAll(Map<? extends K,? extends V> mapEntries)
```
    Store the specified values under the specified keys in the underlying store. This method is intended to support both key/value creation and value update for the specified keys.
    
    Specified by:
    
    storeAll in interface CacheStore<K,V>
    
    Parameters:
    
    mapEntries - a Map of any number of keys and values to store
  - erase
```
public void erase(K key)
```
    Remove the specified key from the underlying store if present.
    
    Specified by:
    
    erase in interface CacheStore<K,V>
    
    Overrides:
    
    erase in class AbstractCacheStore<K,V>
    
    Parameters:
    
    key - key to remove from the store
  - eraseAll
```
public void eraseAll(Collection<? extends K> colKeys)
```
    Remove the specified keys from the underlying store if present.
    
    Specified by:
    
    eraseAll in interface CacheStore<K,V>
    
    Parameters:
    
    colKeys - keys whose mappings are being removed from the cache
  - keys
```
public Iterator<K> keys()
```
    Iterate all keys in the underlying store.
    
    Specified by:
    
    keys in interface IterableCacheLoader<K,V>
    
    Returns:
    
    a read-only iterator of the keys in the underlying store
  - getMap
```
public Map<K,V> getMap()
```
    Returns the Map that this CacheStore uses for its storage.
    
    Returns:
    
    the Map that this CacheStore uses
  - setMap
```
protected void setMap(Map<K,V> map)
```
    Configures the Map that this CacheStore uses for its storage.
    
    Parameters:
    
    map - the Map that this CacheStore will use
