  • Constructor Details

  • Method Details

    • hasNext

      public boolean hasNext()
    • next

      public GridView.Pos next()
    • reset

      GridView.Pos reset(int y, int x, int rightMargin, int bottomMargin)
      Resets grid view and sets it up for processing new element If sparse algorithm is used then x and y positions on a grid are not reset.
      Parameters:
      y - left upper corner y position of an element on the grid
      x - left upper corner x position of an element on the grid
      rightMargin - specifies how many cells not to process at the right end of a grid
      bottomMargin - specifies how many cells not to process at the bottom end of a grid
      Returns:
      first element position
    • fit

      boolean fit(int width, int height)
      Try to fit cell at the current position. If cell is fit, then update current flow cursor axis by width/height of a laid out cell.
      Parameters:
      width - width of the cell
      height - height of the cell
      Returns:
      true if cell is fit, false otherwise
    • resetCursorIfIntersectingCellIsPlaced

      void resetCursorIfIntersectingCellIsPlaced()
      Reset cursor to the start of a grid if placed a cell, which intersects current flow axis. This is needed because such cells should be placed out of order and it's expected that they are go first while constructing the grid.
    • increaseDefaultCursor

      void increaseDefaultCursor(GridView.Pos cellSizes)
      Increase cursor in current flow axis
      Parameters:
      cellSizes - cell width and height values
    • increaseDefaultAxis

      void increaseDefaultAxis()
    • isFixed

      boolean isFixed()
      Determines if current grid view can be iterated.
      Returns:
      true if fixed false otherwise
