    • ready

      void ready()
      Finish creation of a modification, making it ready for application to the data tree. Any calls to this object's methods except applyToCursor(DataTreeModificationCursor) will result in undefined behavior, possibly with an IllegalStateException being thrown.

    • applyToCursor

      void applyToCursor(@NonNull DataTreeModificationCursor cursor)
      Apply the contents of this modification to a cursor. This can be used to replicate this modification onto another one. The cursor's position must match the root of this modification, otherwise performing this operation will result in undefined behavior.
      Parameters:
      cursor - cursor to which this modification
