public abstract class Layout

extends Node

implements PropertyAccess

Layout interface. Layouts remember the position of views. When a layout is activated, the state of the remembered views is recovered from the information saved in the layout.

Method Summary

java.util.Iterator	getChildren() This method is part of the Element interface to provide a convenient way of getting an Iterator over any contained child Elements without having to test the object's type with the instanceof operator or having to downcast to a more specific type.
java.lang.String	getName() Get this layout name.
IdeLayout	getOwner() Get the IdeLayout that owns this layout.
java.lang.String	getShortLabel() Displayable interface method.
boolean	isActive() Returns true if this layout is currently active.
protected boolean	isTrackedInNodeCache() The return value of this method indicates whether this Node should be tracked by the NodeFactory cache.
void	setActive(boolean active) Mark this layout as the currently active layout.
void	setOwner(IdeLayout owner) Set the owner of this layout.
java.lang.String	toString() Returns the Short Label displayed to a user.

Method Detail

getChildren

public java.util.Iterator getChildren()

Description copied from interface: Element

This method is part of the Element interface to provide a convenient way of getting an Iterator over any contained child Elements without having to test the object's type with the instanceof operator or having to downcast to a more specific type.

An implementation of Element that represents a leaf in a tree structure should return null from this method. An implementation of Element that could represent a non-leaf in a tree structure should return either an Iterator over the child Elements or null if there are no children.

Specified by:

getChildren in interface Element

Overrides:

getChildren in class Node

isTrackedInNodeCache

protected boolean isTrackedInNodeCache()

Description copied from class: Node

The return value of this method indicates whether this Node should be tracked by the NodeFactory cache. The default return value is true. Node types that should not be tracked by the NodeFactory cache should override this method to return false.

Overrides:

isTrackedInNodeCache in class Node

Returns:

true if this Node should be tracked by the IDE's NodeFactory cache; false otherwise.

isActive

public boolean isActive()
                 throws TransientMarker

Returns true if this layout is currently active.

Throws:

TransientMarker

setActive

public void setActive(boolean active)

Mark this layout as the currently active layout.

getShortLabel

public java.lang.String getShortLabel()

Description copied from class: Node

Displayable interface method. The Node class returns the file name part of the currently set URL. If the currently set URL is null, then this method returns "<null>".

Specified by:

getShortLabel in interface Displayable

Overrides:

getShortLabel in class Node

getName

public java.lang.String getName()

Get this layout name.

getOwner

public IdeLayout getOwner()
                   throws TransientMarker

Get the IdeLayout that owns this layout.

Throws:

TransientMarker

setOwner

public void setOwner(IdeLayout owner)

Set the owner of this layout.

toString

public java.lang.String toString()

Description copied from interface: Displayable

Returns the Short Label displayed to a user. This overrides the toString method in java.lang.Object.

Implementors of the Displayable interface should override this as appropriate. The default implementation is the same as getShortLabel

Specified by:

toString in interface Displayable

Overrides:

toString in class Node
