Examples of org.eclipse.jface.text.TextSelection

org.eclipse.jface.text.TextSelection
Standard implementation of {@link org.eclipse.jface.text.ITextSelection}.
Makes advantage of the weak contract of correctness of its interface. If generated from a selection provider, it only remembers its offset and length and computes the remaining information on request.
