clear method

void clear()

Clear out all references to any model data. This also clears out the UndoManager, so this operation is not undoable. This method is called by Diagram#clear; it does not notify any Diagrams or other listeners. This method does not unregister any Changed event listeners.

Instead of calling this method, you may prefer to set #nodeDataArray to an empty JavaScript Array. If this model is a GraphLinksModel, you would also want to set GraphLinksModel#linkDataArray to a separate empty JavaScript Array.

Implementation

void clear() {
  _i4.callMethod(
    this,
    'clear',
    [],
  );
}
