Method Detail

updateSelection

public boolean updateSelection(
IStructuredSelection selection)
Description copied from class: SystemBaseAction
First opportunity to decide if the action should be enabled or not based on the current selection. Called by default implementation of selectionChanged, which converts the ISelection to an IStructuredSelection, which is all we support. The return result is used to enable or disable this action.

The default implementation of this method:

  • Returns false if calling checkObjectType on any object in the selection list returns false.
  • Returns true otherwise.
If desired, override this method for a different algorithm to decide enablement.

Overrides:
updateSelection in class SystemBaseAction
See Also:
SystemBaseAction.updateSelection(IStructuredSelection)

run

public void run()
This is the method called when the user selects this action.

Specified by:
run in interface IAction
Overrides:
run in class SystemBaseAction
See Also:
Action.run()
