Returns the files mapped with the ISaveContext.map(IPath, IPath)
facility. |

IPath[] getFiles()
ISaveContext.map(IPath, IPath)
facility. Returns an empty array if there are no mapped files.
lookup(IPath),
ISaveContext.map(IPath, IPath)int getSaveNumber()
0 if the plug-in has
never actively participated in a successful save.
IPath lookup(IPath file)
null if none.
getFiles(),
ISaveContext.map(IPath, IPath)void processResourceChangeEvents(IResourceChangeListener listener)
No notification is received in the following cases:
ISaveContext.needDelta()
was not called) IWorkspace.forgetSavedTree(String)) All clients should have a contingency plan in place in case a changes are not available (the case should be very similar to the first time a plug-in is activated, and only has the current state of the workspace to work from).
The supplied event is of type IResourceChangeEvent.POST_BUILD
and contains the delta detailing changes since this plug-in last participated
in a save. This event object (and the resource delta within it) is valid only
for the duration of the invocation of this method.
