      Parameters:
      data - the array holding the data-objects.
      selection - the selection of which elements should be pushed up.

    • pushDown

      public static void pushDown(Object[] data, boolean[] selection)
      Pushes the selected elements down. The elements are given in the data-array, while a selector on whether they should be pushed down is given in the selection array. The operation modifies the data-array.
      Parameters:
      data - the array holding the data-objects.
      selection - the selection of which elements should be pushed down.

    • pushUpSingleValue

      public static void pushUpSingleValue(Object[] data, Object selection)
      Pushes up the selected element. The element is compared via reference-equality, so equals() will not be called. It is assumed that the selected object is part of the data-collection. The operation modifies the data-array.
      Parameters:
      data - the array holding the data-objects.
      selection - the selectioned object that be pushed up.

    • pushDownSingleValue

      public static void pushDownSingleValue(Object[] data, Object selection)
