protected void	addToParentInfo(Openable child)	Adds the given child handle to its parent's cache of children.
protected static void	close(Openable element)	Closes the given element, which removes it from the cache of open elements.
protected void	elementAdded(Openable element)	Processing for an element that has been added: If the element is a project, do nothing, and do not process children, as when a project is created it does not yet have any natures - specifically a java nature.
protected void	elementChanged(Openable element)	Generic processing for elements with changed contents: The element is closed such that any subsequent accesses will re-open the element reflecting its new structure.
protected void	elementRemoved(Openable element)	Generic processing for a removed element: Close the element, removing its structure from the cache Remove the element from its parent's cache of children Add a REMOVED entry in the delta
void	processJavaDelta(IJavaElementDelta delta)	Converts a IResourceDelta rooted in a Workspace into the corresponding set of IJavaElementDelta, rooted in the relevant JavaModels.
protected void	removeFromParentInfo(Openable child)	Removes the given element from its parents cache of children.
protected void	traverseDelta(IJavaElementDelta delta, IPackageFragmentRoot root, IJavaProject project)	Converts an IResourceDelta and its children into the corresponding IJavaElementDeltas.

Methodendetails

addToParentInfo

protected void addToParentInfo(Openable child)

Adds the given child handle to its parent's cache of children.

close

protected static void close(Openable element)

Closes the given element, which removes it from the cache of open elements.

elementAdded

protected void elementAdded(Openable element)

Processing for an element that has been added:

• If the element is a project, do nothing, and do not process children, as when a project is created it does not yet have any natures - specifically a java nature.
• If the elemet is not a project, process it as added (see basicElementAdded.

elementChanged

protected void elementChanged(Openable element)

Generic processing for elements with changed contents:

• The element is closed such that any subsequent accesses will re-open the element reflecting its new structure.

elementRemoved

protected void elementRemoved(Openable element)

Generic processing for a removed element:

• Close the element, removing its structure from the cache
• Remove the element from its parent's cache of children
• Add a REMOVED entry in the delta

processJavaDelta

public void processJavaDelta(IJavaElementDelta delta)

Converts a IResourceDelta rooted in a Workspace into the corresponding set of IJavaElementDelta, rooted in the relevant JavaModels.

removeFromParentInfo

protected void removeFromParentInfo(Openable child)

Removes the given element from its parents cache of children. If the element does not have a parent, or the parent is not currently open, this has no effect.

traverseDelta

protected void traverseDelta(IJavaElementDelta delta,
 IPackageFragmentRoot root,
 IJavaProject project)

Converts an IResourceDelta and its children into the corresponding IJavaElementDeltas. Return whether the delta corresponds to a resource on the classpath. If it is not a resource on the classpath, it will be added as a non-java resource by the sender of this method.
