public class AggregateFeatureSet

extends AbstractFeatureSet

implements FeatureSetListener

FeatureSet that aggregates other FeatureSets and forwards messages to them. It is used by AbstractFeatureModel to allocate sets of children for Features.

AbstractFeatureModel.getChildFeatureSet(Feature)

Fields inherited from class com.inline.feature.common.AbstractResourceListener

Constructor Summary

AggregateFeatureSet(Feature parent)

Method Summary

protected void	activate() Registers this object as an observer on all registered resource adapters and resource set adapters, then it calls invalidate() on self to restart the resource parsing process.
void	addFeatureSet(java.lang.String type, FeatureSet set)
protected Feature	allocateFeature(java.lang.String type, java.lang.String signature)
void	featureAdded(FeatureSet set, Feature feature)
void	featureRemoved(FeatureSet set, Feature feature)
void	featureReplaced(FeatureSet set, Feature oldFeature, Feature newFeature)
Feature	getFeature(java.lang.String type, java.lang.String signature) Finds the feature that has the specified type and signature
com.sun.java.util.collections.Set	getFeatureConstructors() Returns a set of FeatureConstructor objects suitable for the use in the context of this feature set's parent.
com.sun.java.util.collections.Set	getFeatures() Returns all features handled by this set.
com.sun.java.util.collections.Set	getFeatures(java.lang.String type) Returns a subset of features which have the specified type.
protected com.sun.java.util.collections.Set	getPrimitiveFeatureConstructors(java.lang.String type) Returns a set of basic feature constructors which can be used to build features of the specified type.
Feature[]	getSortedFeatures() Returns features sorted according to their DisplayProperty's preferences.
boolean	isEmpty() This method exists for optimization purposes.
protected void	passivate() Unregisters this object as an observer from all registered resource adapters and resource set adapters.
void	release() This method is called when the parent feature is removed from the feature tree.

Method Detail

addFeatureSet

public void addFeatureSet(java.lang.String type,
                          FeatureSet set)

allocateFeature

protected Feature allocateFeature(java.lang.String type,
                                  java.lang.String signature)

getFeatures

public com.sun.java.util.collections.Set getFeatures()

Description copied from interface: FeatureSet

Returns all features handled by this set. The result may not reflect real situation if the feature set is inactive.

getFeatures

public com.sun.java.util.collections.Set getFeatures(java.lang.String type)

Description copied from interface: FeatureSet

Returns a subset of features which have the specified type. Will return null if the specified type is not a supported child type for this feature.

getFeature

public Feature getFeature(java.lang.String type,
                          java.lang.String signature)

Description copied from interface: FeatureSet

Finds the feature that has the specified type and signature

getSortedFeatures

public Feature[] getSortedFeatures()

Description copied from interface: FeatureSet

Returns features sorted according to their DisplayProperty's preferences.

isEmpty

public boolean isEmpty()

Description copied from interface: FeatureSet

This method exists for optimization purposes. Some FeatureSets will be able to answer this question without actually building a set of features.

activate

protected void activate()

Description copied from class: AbstractResourceListener

Registers this object as an observer on all registered resource adapters and resource set adapters, then it calls invalidate() on self to restart the resource parsing process.

Overrides:

activate in class AbstractResourceListener

Tags copied from class: AbstractResourceListener

See Also:

AbstractFeature.addPropertyChangeListener(PropertyChangeListener), AbstractFeatureSet.addFeatureSetListener(FeatureSetListener)

passivate

protected void passivate()

Description copied from class: AbstractResourceListener

Unregisters this object as an observer from all registered resource adapters and resource set adapters.

Overrides:

passivate in class AbstractResourceListener

Tags copied from class: AbstractResourceListener

See Also:

AbstractFeature.removePropertyChangeListener(PropertyChangeListener), AbstractFeatureSet.removeFeatureSetListener(FeatureSetListener)

release

public void release()

Description copied from interface: FeatureSet

This method is called when the parent feature is removed from the feature tree. The set should unregister itself from everything it was listening to and forward the message to all child features.

Overrides:

release in class AbstractResourceListener

getFeatureConstructors

public com.sun.java.util.collections.Set getFeatureConstructors()

Description copied from interface: FeatureSet

Returns a set of FeatureConstructor objects suitable for the use in the context of this feature set's parent.

getPrimitiveFeatureConstructors

protected com.sun.java.util.collections.Set getPrimitiveFeatureConstructors(java.lang.String type)

Description copied from class: AbstractFeatureSet

Returns a set of basic feature constructors which can be used to build features of the specified type. Other, non-primitive, constructors will have to be coded in terms of other constructors, they cannot produce features directly. The non-primitive constructors are produced by FeatureConstructorFactories.

Overrides:

getPrimitiveFeatureConstructors in class AbstractFeatureSet

featureAdded

public void featureAdded(FeatureSet set,
                         Feature feature)

Specified by:

featureAdded in interface FeatureSetListener

featureRemoved

public void featureRemoved(FeatureSet set,
                           Feature feature)

Specified by:

featureRemoved in interface FeatureSetListener

featureReplaced

public void featureReplaced(FeatureSet set,
                            Feature oldFeature,
                            Feature newFeature)

Specified by:

featureReplaced in interface FeatureSetListener
