    • copy

      Block copy(Map<UUID,UUID> newIds)
      Copy the settings of this block into a new block instance. Any outgoing connections originating at this block should also be copied. If the destination of those connections is in the id set, it should point to the new block.
      Parameters:
      newIds - a map of all new ids for copied blocks (including this one). Should be used to point outgoing connections to blocks in the copied set to their new ids.

      Collection<AnchorPoint> getAnchorPoints()
      The valid origins and terminus points for connectors coming into or out of this block

    • getDefaultDropAnchor

      AnchorPoint getDefaultDropAnchor(AnchorPoint oppositeAnchor)
      When a connector is being dropped on this block, what anchor point should it attach to if it isn't specifically over an anchor's hotspot (may return null)
      Parameters:
      oppositeAnchor - The anchor point that would be the opposite anchor on the connector being hovered over this block.

    • initUI
