Class DefaultCompositeFileElementProxy

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

All Implemented Interfaces:

CompositeFileElementProxy

public class DefaultCompositeFileElementProxy

extends java.lang.Object

implements CompositeFileElementProxy

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.

Constructor Detail

DefaultCompositeFileElementProxy

public DefaultCompositeFileElementProxy(java.lang.Class compositeElementClass)

Constructs a DefaultCompositeFileElementProxy object.

Parameters:

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.

Specified by:

getCompositeElementClass in interface CompositeFileElementProxy

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.

Specified by:

getCompositeFileURLs in interface CompositeFileElementProxy

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)
