Class HandlerSocketCache<T extends org.dasein.util.CachedItem>

java.lang.Object
  org.dasein.persist.PersistentCache<T>
      org.dasein.persist.HandlerSocketCache<T>

public class HandlerSocketCache<T extends org.dasein.util.CachedItem>
extends PersistentCache<T>

Implements HanderSocket. You must use indexes (like PRIMARY) to access data.

TODO: Handle translation field types!

Method Detail

init

protected void init(Class<T> cls,
                    Key... keys)

Constructs a new persistent factory for objects of the specified class with the named unique identifier attributes.

Overrides:

init in class PersistentCache<T extends org.dasein.util.CachedItem>

Parameters:

cls - the class of objects managed by this factory

keys - a list of unique identifiers for instances of the specified class

create

public T create(Transaction xaction,
                Map<String,Object> state)
                                            throws PersistenceException
