Interface Displayable

All Known Subinterfaces:

Feature, FeatureAction, FeatureConstructor

All Known Implementing Classes:

AbstractDisplayable

public interface Displayable

Displayable objects are designed to play the role of model in the MV (model-view) or controller in the MVC (model-view-controller) pattern. The role of view is played in both cases by the classes implementing the DisplayProperties interface.

The binding between a Displayable and the DisplayProperties is dynamic. The information binding a Displayable to its DisplayProperties is a logical name called display type. To find its DisplayProperties, a Displayable object involves external DisplayPropertyFactories. It looks up a factory that can provide DisplayProperties for the required display type and invokes that factory to produce the DisplayProperty object.

Method Summary

DisplayProperties	getDisplayProperties() Returns display properties for this displayable object.
java.lang.String	getDisplayType() Displayable objects are bound to their display properties using an abstract identifier called display type.

Method Detail

getDisplayType

public java.lang.String getDisplayType()

Displayable objects are bound to their display properties using an abstract identifier called display type. Ask a displayable object for its display type, then go find a DisplayPropertyFactory that accepts that display type. That is the sole purpose of display type.

getDisplayProperties

public DisplayProperties getDisplayProperties()

Returns display properties for this displayable object. This method should lookup a DisplayPropertyFactory that supports this object's display type and request a DisplayProperty object from that factory. For example, AbstractFeature, AbstractFeatureAction, AbstractFeatureConstructor, etc all delegate the factory lookup to their FeatureModel.
