Class AttributeManager

java.lang.Object
  pl.edu.agh.cast.model.attributes.AttributeManager

All Implemented Interfaces:

java.beans.PropertyChangeListener, java.io.Serializable, java.util.EventListener, IPropertyChangeProvider

Direct Known Subclasses:

ConnectionGroupAttributeManager, DiagramAttributeManager, LegendAttributeManager, NodeAttributeManager

public abstract class AttributeManager
extends java.lang.Object
implements java.io.Serializable, IPropertyChangeProvider, java.beans.PropertyChangeListener

Class responsible for holding available attribute types for different model element types. Available attribute types are specific for model element types, such as Node, ConnectionGroup, Legend etc. For convenience, the manager acts as a forwarder of all events fired by its registered attributes. Events have ID ATTRIBUTES_PROPERTY_CHANGE, and oldValue set to corresponding PropertyChangeEvent object that is being forwarded.
