protected String getOperationMessage()
WorkspaceAction
Note that this hook method is invoked in a non-UI thread.
Subclasses must implement this method.
getOperationMessage
in class WorkspaceAction
protected 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 WorkspaceAction
protected 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.
getProblemsTitle
in class WorkspaceAction
protected void invokeOperation(IResource resource, IProgressMonitor monitor) throws CoreException
WorkspaceAction
Note that this method is invoked in a non-UI thread.
Subclasses must implement this method.

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

OpenResourceAction
implementation of this
SelectionListenerAction
method ensures that this action is
enabled only if one of the selections is a closed project.

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