Class FKCache

public class FKCache extends AbstractBaseCache

JCACHE implementation of Castor JDO Cache. JCACHE is the Java Temporary Caching API (JSR-107).

elements

public Enumeration elements()
Returns an enumeration of the values in this LRU map. Use the Enumeration methods on the returned object to fetch the elements sequentially.

Returns: an enumeration of the values in this Map.

entrySet

public Set entrySet()

get

public Object get(Object key)
Returns the value to which the specified key is mapped in this Map.

Parameters: key - a key in the Map.

Returns: the value to which the key is mapped in this Map; null if the key is not mapped to any value in this Map.

initialize

public void initialize()

isEmpty

public boolean isEmpty()

keySet

public Set keySet()

put

public Object put(Object key, Object value)
Maps the specified key to the specified value in this Map. Neither the key nor the value can be null.

The value can be retrieved by calling the get method with a key that is equal to the original key.

Parameters: key the Map key. value the value.

Returns: the previous value of the specified key in this Map, or null if it did not have one.

Throws: NullPointerException if the key or value is null.

public void putAll(Map aMap)

remove

public Object remove(Object key)
Removes the key (and its corresponding value) from this Map. This method does nothing if the key is not in the Map.

Parameters: key the key that needs to be removed.

Returns: the value to which the key had been mapped in this Map, or null if the key did not have a mapping.
