Detailed Description

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.

Member Function Documentation

virtual void berry::ISourceProviderListener::SourceChanged ( int  sourcePriority,
const QHash< QString, Object::ConstPointer > &  sourceValuesByName 
)
pure virtual

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
sourcePriorityA bit mask of all the source priorities that have changed.
sourceValuesByNameA 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).

virtual void berry::ISourceProviderListener::SourceChanged ( int  sourcePriority,
const QString &  sourceName,
Object::ConstPointer  sourceValue 
)
pure virtual

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
sourcePriorityA bit mask of all the source priorities that have changed.
sourceNameThe name of the source that changed; must not be null.
sourceValueThe new value for that source; may be null.
