Class SelectionManager


  • public class SelectionManager
    extends java.lang.Object
    Manages a viewer's selection model. Selection management includes representing a form of selection which is available to clients of a viewer as an ISelection. It also includes managing the notion of focus, which is closely tied to the current selection. The selection manager provides the mechanism for modifying the selection and any validation.
