Method Detail

create

public void create()
            throws InstantiationException

Initializes and fills in the fields of this object. This method must create the type, the controller objects and the interfaces of a component. The default implementation of this method does nothing.

Throws:

InstantiationException - if the component type, a controller object or a component interface cannot be created.

getInterface

public Object getInterface(String name)
                    throws InstantiationException

Returns the component interface of the interfaces map whose name is given.

Parameters:

name - the name of a component interface.

Returns:

the interface whose name is given.

Throws:

InstantiationException - if there is no such component interface.

getOptionalInterface

public Object getOptionalInterface(String name)

Returns the component interface of the interfaces map whose name is given.

Parameters:

name - the name of a component interface.

Returns:

the interface whose name is given, or null if there is no such component interface.
