Class LayeredRenderer

java.lang.Object
  org.biojava.bio.gui.sequence.LayeredRenderer

public class LayeredRenderer
extends Object

LayeredRenderer handles the lane offsets for MultiLineRenders. For each successive lane it translates the Graphics2D perpendicular to the sequence rendering direction by an amount equal to the value returned by the getDepth() method of that lane's renderer.
