Class AbstractSourceLookupDirector
- All Implemented Interfaces:
ILaunchConfigurationListener
,ILaunchListener
,IPersistableSourceLocator
,ISourceLocator
,IPersistableSourceLocator2
,ISourceLookupDirector
When a source director is initialized, it adds it self as a launch listener, and automatically disposes itself when its associated launch is removed from the launch manager. If a source director is instantiated by a client that is not part of a launch, that client is responsible for disposing the source director.
Clients may subclass this class.

getSourceElement
Description copied from interface:ISourceLocator
Returns a source element that corresponds to the given stack frame, ornull

The debug UI uses the debug model presentation associated with the given stack frame's debug model to translate a source object into an {editor input, editor id} pair in which to display source.For example, a java source locator could return an object representing a compilation unit or class file. The java debug model presentation would then be responsible for providing an editor input and editor id for each compilation unit and class file such that the debug UI could display source.

getSourceElement
in interfaceISourceLocator
- Parameters:
stackFrame
- the stack frame for which to locate source- Returns:
- an object representing a source element.

This method is called when more than one source element has been found for an element, and allows the source director to select a single source element to associate with the element.Subclasses should override this method as appropriate. For example, to prompt the user to choose a source element.
- Parameters:
element
