Class WebDerivedElementsEditorObject

  • All Implemented Interfaces:
    EnumWebPersistableState, Persistable, WebDerivedElements, EnumDSSXMLReportManipulationMethod
    public class WebDerivedElementsEditorObject
extends AbstractPersistable
    This class represents derived elements inside derived elements editor. All changes performed by a user inside the editor are kept there until user clicks OK button. Then all accumulated changes are applied to the target template attribute derived elements. To support this we accumulated all generated deltas in a local buffer.
    Since:
    MicroStrategy Web 9.0.0

    • Method Detail

      • hasVisibleList

        public boolean hasVisibleList()
