Examples of com.cburch.logisim.data.Location

com.cburch.logisim.data.Location
Represents an immutable rectangular bounding box. This is analogous to java.awt's Point class, except that objects of this type are immutable.

  public Bounds getOffsetBounds() {
    InstanceComponent c = comp;
    if (c == null) {
      return factory.getOffsetBounds(attrs);
    } else {
      Location loc = c.getLocation();
      return c.getBounds().translate(-loc.getX(), -loc.getY());
    }
  }
