Class AbstractAggregateContent<C extends TransformableContent>

java.lang.Object

visual.statik.AbstractTransformableContent

visual.statik.AbstractAggregateContent<C>

All Implemented Interfaces:

SimpleContent, TransformableContent

Direct Known Subclasses:

AggregateContent, AggregateContent, CompositeContent, CompositeContent, CompositeContent

public abstract class AbstractAggregateContent<C extends TransformableContent>
extends AbstractTransformableContent

A generic piece of static visual content that is a composition of many component parts.

Note: The bounds are not stored in attributes to make this class easier to understand. To do so would require: (1) Use of the isTransformationRequired() method in the parent; and (2) Changes to the add() and remove() methods in this class.
