Method Detail

findSelection
public org.eclipse.jface.viewers.IStructuredSelection findSelection(org.eclipse.ui.IEditorInput editorInput)
This implementation uses the
input element providerto convert the given editor input to anIElement(the input element).

Otherwise, it returns a structured selection containing a single object, the input element. If noIElementcould be provided for the editor input, this implementation attempts to adapt the editor input to anIFileand returns a structured selection consisting of that file. If all else fails,nullis returned.- Specified by:
