Method Detail

findSelection
public org.eclipse.jface.viewers.IStructuredSelection findSelection(org.eclipse.ui.IEditorInput editorInput)
This implementation uses the
input element provider
to convert the given editor input to anIElement
(the input element). It then attempts to obtain the current selection in thenavigator view
and returns it unchanged if the currently selected element could be adapted to anIElement
and the adapter element is a descendant of the input element. Otherwise, it returns a structured selection containing a single object, the input element. If noIElement
could be provided for the editor input, this implementation attempts to adapt the editor input to anIFile
and returns a structured selection consisting of that file. If all else fails,null
is returned.- Specified by:

activateEditor
public void activateEditor(org.eclipse.ui.IWorkbenchPage page, org.eclipse.jface.viewers.IStructuredSelection selection)

or empty or contains two or more elements. Otherwise, it uses theeditor utility
to find the editor for the selected element and to reveal the element in the editor.- Specified by:
