public class OpenResourceAction extends WorkspaceAction implements IResourceChangeListener
Note that there is a different action for opening an editor on file
resources: OpenFileAction.
This class may be instantiated; it is not intended to be subclassed.

|---|---|
protected String |
getOperationMessage()
Returns the string to display for this action's operation.
|
protected String |
getProblemsMessage()
Returns the string to display for this action's problems dialog.
|
protected String |
getProblemsTitle()

|
protected void |
invokeOperation(IResource resource,
IProgressMonitor monitor)
Performs this action's operation on each of the selected resources, reporting
progress to, and fielding cancel requests from, the given progress monitor.
|
void |
resourceChanged(IResourceChangeEvent event)
Handles a resource changed event by updating the enablement if one of the
selected projects is opened or closed.
|
void |
run()
The
CoreWrapperAction implementation of this IAction
method uses a ProgressMonitorDialog to run the operation. |
protected boolean |
shouldPerformResourcePruning()
Returns whether this action should attempt to optimize the resources being
operated on.
|
protected boolean |
updateSelection(IStructuredSelection s)
The
OpenResourceAction implementation of this
SelectionListenerAction method ensures that this action is
enabled only if one of the selections is a closed project. |

WorkspaceActionNote that this hook method is invoked in a non-UI thread.
Subclasses must implement this method.
getOperationMessage in class WorkspaceActionprotected String getProblemsMessage()
WorkspaceAction
The WorkspaceAction implementation of this method returns a
vague message (localized counterpart of something like "The following
problems occurred."). Subclasses may reimplement to provide something more
suited to the particular action.
getProblemsMessage in class WorkspaceActionprotected String getProblemsTitle()
WorkspaceAction
The WorkspaceAction implementation of this method returns a
generic title (localized counterpart of "Problems"). Subclasses may
reimplement to provide something more suited to the particular action.

WorkspaceActionNote that this method is invoked in a non-UI thread.
Subclasses must implement this method.

WorkspaceActionCoreWrapperAction implementation of this IAction
method uses a ProgressMonitorDialog to run the operation. The
operation calls execute (which, in turn, calls
invokeOperation). Afterwards, any CoreExceptions
encountered while running the operation are reported to the user via a
problems dialog.
Subclasses may extend this method.

The WorkspaceAction implementation of this method returns
true. Subclasses should reimplement to return false
if pruning is not required.
