    • getLargestRectangle

      public static PortalUtil.Rectangle getLargestRectangle​(BlockPos center, Direction.Axis primaryAxis, int primaryMaxBlocks, Direction.Axis secondaryAxis, int secondaryMaxBlocks, Predicate<BlockPos> predicate)
      Gets the largest rectangle of blocks along two axes for which all blocks meet a predicate. Used for getting rectangles of Nether portal blocks.

    • findLargestRectangle

      static com.mojang.datafixers.util.Pair<PortalUtil.IntBounds,​Integer> findLargestRectangle​(int[] heights)
      Finds the largest rectangle within a histogram, where the vertical bars each have width 1 and height specified in heights.
      Parameters:
      heights - the heights of bars in the histogram
      Returns:
      the base of the rectangle as an inclusive range and the height of the rectangle packed in a pair
      See Also:
      Largest Rectangle in Histogram - LeetCode
      Implementation Note:
      This implementation solves the problem using a stack. The stack maintains a collection of height limits of rectangles that may grow as the array iteration continues. When a new height is encountered, each position p in the stack would be popped if the rectangle with height limit at position p can no longer extend right. The popped rectangle becomes the return value if it has a larger area than the current candidate.

      When the rectangle area is calculated, the range is between p0 + 1, where p0 is the current top of stack after popping rectangles that can no longer extend, and the current iterated position i.
