Constructor Summary
WorkbenchObservables ()
           
 
Method Summary
static  IObservableValue observeAdaptedSingleSelection ( IServiceLocator locator, Class targetType)
          Returns an observable value that tracks the post selection of a selection service obtained through the given service locator, and adapts the first element of that selection to the given target type.
static  IObservableValue observeDetailAdaptedValue ( IObservableValue master, Class adapter)
          Returns an observable with values of the given target type.

Method Detail

observeDetailAdaptedValue

public static 
IObservableValue observeDetailAdaptedValue(
IObservableValue master,
                                                         
Class adapter)
Returns an observable with values of the given target type. If the wrapped observable's value is of the target type, or can be adapted to the target type, this is taken as the value of the returned observable, otherwise null.

Parameters:
master - the observable whose value should be adapted
adapter - the target type
Returns:
an observable with values of the given type, or null if the current value of the given observable does not adapt to the target type

observeAdaptedSingleSelection

public static 
IObservableValue observeAdaptedSingleSelection(
IServiceLocator locator,
                                                             
Class targetType)
Returns an observable value that tracks the post selection of a selection service obtained through the given service locator, and adapts the first element of that selection to the given target type.

This method can be used by view or editor implementers to tie into the selection service, for example as follows:

 IObservableValue selection = WorkbenchObservables
                .observeAdaptedSingleSelection(getSite(), IResource.class);
 

Parameters:
locator - a service locator with an available ISelectionService
targetType - the target type
Returns:
an observable value whose value type is the given target type
