Eclipse Platform
Release 3.5

org.eclipse.ui
Interface ISourceProviderListener


public interface ISourceProviderListener

A listener to changes in a particular source of information. This listener is notified as the source changes. Typically, workbench services will implement this interface, and register themselves as listeners to the ISourceProvider instances that are registered with them.

Since:
3.1
See Also:
ISources, ISourceProvider

Method Summary
 void sourceChanged (int sourcePriority, Map sourceValuesByName)
          Handles a change to multiple sources.
 void sourceChanged (int sourcePriority, String sourceName, Object sourceValue)
          Handles a change to one source.
 

Method Detail

sourceChanged

void sourceChanged(int sourcePriority,
                   
Map sourceValuesByName)
Handles a change to multiple sources. The source priority should be a bit mask indicating the sources. The map will be used to construct the variables on an IEvaluationContext

Parameters:
sourcePriority - A bit mask of all the source priorities that have changed.
sourceValuesByName - A mapping of the source names (String) to the source values (Object). The names should never be null, but the values may be. The map must not be null, and should contain at least two elements (one for each source).
See Also:
IEvaluationContext, ISources

sourceChanged

void sourceChanged(int sourcePriority,
                   
String sourceName,
                   
Object sourceValue)
Handles a change to one source. The source priority should indicate the source, and the name-value pair will be used to create an IEvaluationContext with a single variable.

Parameters:
sourcePriority - A bit mask of all the source priorities that have changed.
sourceName - The name of the source that changed; must not be null.
sourceValue - The new value for that source; may be null.
