- Method Detail
  - addSourceProvider
```
void addSourceProvider(ISourceProvider provider)
```
    Adds a source provider to this service. A source provider will notify the service when the source it provides changes. An example of a source might be an active editor or the current selection. This amounts to a pluggable state tracker for the service.
    
    Parameters:
    
    provider - The provider to add; must not be null.
  - removeSourceProvider
```
void removeSourceProvider(ISourceProvider provider)
```
    Removes a source provider from this service. Most of the time, this method call is not required as source providers typically share the same life span as the workbench itself.
    
    Parameters:
    
    provider - The provider to remove; must not be null.
