oracle.ide.composite
Class DefaultCompositeFileElementProxy

java.lang.Object
oracle.ide.composite.AbstractCompositeFileElementProxy
oracle.ide.composite.DefaultCompositeFileElementProxy

All Implemented Interfaces:

CompositeFileElementProxy

public class DefaultCompositeFileElementProxy

extends AbstractCompositeFileElementProxy

The default implementation class for a CompositeFileElementProxy based on a container-style composite element type. An observer is attached to the composite elements of this proxy type to fire a composite state change event through the registry class when the container state is modified.

Constructor Summary

DefaultCompositeFileElementProxy(java.lang.Class compositeElementClass)
Constructs a DefaultCompositeFileElementProxy object.

DefaultCompositeFileElementProxy(java.lang.String viewType, java.lang.Class compositeElementClass)
Constructs a DefaultCompositeFileElementProxy object.

Method Summary

protected void	addChildURLs(java.util.Collection compositeFileUrls, Element parent)
protected void	addLocatableURL(java.util.Collection compositeFileUrls, java.lang.Object o)
protected void	addParentURL(java.util.Collection compositeFileUrls, Element parent)
protected void	attachContainerStateObserver(Element element) Attaches a container state observer to the given element and its children.
java.lang.Class	getCompositeElementClass() Gets the composite element class handled by this proxy.
java.net.URL[]	getCompositeFileURLs(Element compositeElement) Gets the file URLs represented by the given composite element, attaching a container state observer to all composite children.
protected java.util.Collection	getContainerFileURLs(Element compositeElement) Gets the file URLs represented by the given composite element.
protected boolean	isContainerStyleRecursive() Asks whether this proxy behaves recursively with respect to its composite elements.

Constructor Detail

DefaultCompositeFileElementProxy

public DefaultCompositeFileElementProxy(java.lang.Class compositeElementClass)

Constructs a DefaultCompositeFileElementProxy object.

Parameters:

compositeElementClass - the class of composite elements for the proxy.

DefaultCompositeFileElementProxy

public DefaultCompositeFileElementProxy(java.lang.String viewType,
                                        java.lang.Class compositeElementClass)

Constructs a DefaultCompositeFileElementProxy object.

Parameters:

viewType - the type of views associated with this proxy.

compositeElementClass - the class of composite elements for the proxy.

Method Detail

getCompositeElementClass

public java.lang.Class getCompositeElementClass()

Gets the composite element class handled by this proxy. By default, returns the class with which this proxy instance was constructed.

Returns:

the composite element class.

getCompositeFileURLs

public java.net.URL[] getCompositeFileURLs(Element compositeElement)

Gets the file URLs represented by the given composite element, attaching a container state observer to all composite children.

Parameters:

compositeElement - the composite element.

Returns:

the composite file URLs.

attachContainerStateObserver

protected void attachContainerStateObserver(Element element)

Attaches a container state observer to the given element and its children.

Parameters:

element - the element.

getContainerFileURLs

protected java.util.Collection getContainerFileURLs(Element compositeElement)

Gets the file URLs represented by the given composite element. By default, this includes all child elements that implement the Locatable interface and the element itself, if also a Locatable.

Parameters:

compositeElement - the composite element.

Returns:

the composite file URLs.

isContainerStyleRecursive

protected boolean isContainerStyleRecursive()

Asks whether this proxy behaves recursively with respect to its composite elements. By default, returns true.

Returns:

a verdict on recursive container behavior.

addParentURL

protected void addParentURL(java.util.Collection compositeFileUrls,
                            Element parent)

addChildURLs

protected void addChildURLs(java.util.Collection compositeFileUrls,
                            Element parent)

addLocatableURL

protected void addLocatableURL(java.util.Collection compositeFileUrls,
                               java.lang.Object o)
