Method Detail

instantiate

public Object instantiate()

Description copied from interface: Instantiator

Perform the requested instantiation.

Specified by:

instantiate in interface Instantiator

Returns:

The instantiated data structure.

applyInterception

instantiate

public Object instantiate(Serializable id)

Description copied from interface: Instantiator

Perform the requested entity instantiation.

instantiate in interface Instantiator

Parameters:

id - The id of the entity to be instantiated.

Returns:

An appropriately instantiated entity.

isInstance

public boolean isInstance(Object object)

Description copied from interface: Instantiator

Specified by:

isInstance in interface Instantiator

Parameters:

object - The object to be checked.
