Description copied from class: Component

Returns the (informational) name of the component.

Overrides:

getName in class Component

info

public java.lang.String info()

Description copied from class: Component

Returns information regarding this component. Subclasses should override this method to provide useful information at run time.

Overrides:

info in class Component

duplicate

public void duplicate(java.lang.Object source_)

Description copied from class: Component
