public class ChangeEventSource

extends HashStructureAdapter

Implements the registry of ChangeListeners. This class is a helper for objects registered as IdeSettings.registerData()

Constructor Summary

	ChangeEventSource() Creates a default ChangeEventSource.
protected	ChangeEventSource(HashStructure hash) Creates a ChangeEventSource using the specified HashStructure for storage.

Method Summary

void	addChangeListener(javax.swing.event.ChangeListener l)
java.lang.Object	copyTo(java.lang.Object target) Copy support.
void	fireChangeEvent() Note: explicit calls to this method may result in duplicate event firings.
protected void	fireChangeEvent(java.lang.Object source)
void	removeChangeListener(javax.swing.event.ChangeListener l)
protected void	setUseObjectEquals() Subclasses that are fully migrated to HashStructureAdapter semantics need to stub out this method until all ChangeEventSource impls are proper HashStructureAdapters.

Constructor Detail

ChangeEventSource

public ChangeEventSource()

Creates a default ChangeEventSource.

ChangeEventSource

protected ChangeEventSource(HashStructure hash)

Creates a ChangeEventSource using the specified HashStructure for storage.

Method Detail

setUseObjectEquals

protected void setUseObjectEquals()

Subclasses that are fully migrated to HashStructureAdapter semantics need to stub out this method until all ChangeEventSource impls are proper HashStructureAdapters.

copyTo

public java.lang.Object copyTo(java.lang.Object target)

Description copied from class: HashStructureAdapter

Copy support. The specified target must not be null and must be the exact same type as this instance.

Overrides:

copyTo in class HashStructureAdapter

addChangeListener

public void addChangeListener(javax.swing.event.ChangeListener l)

removeChangeListener

public void removeChangeListener(javax.swing.event.ChangeListener l)

fireChangeEvent

public void fireChangeEvent()

Note: explicit calls to this method may result in duplicate event firings. Events should get sent automatically whenever a change occurs on the underlying HashStructure. Fires a stateChanged event with 'this' as the source of the event. It is by design that the current implementation does not allow to specify the source of the event from the public API.

fireChangeEvent

protected final void fireChangeEvent(java.lang.Object source)
