Class RandomIncrLayout

  • All Implemented Interfaces:
    GlobalLayout, IncrementalLayout
    public class RandomIncrLayout
extends java.lang.Object
implements IncrementalLayout
    Randomly place newly-added nodes within the target viewport. This class tries to be smart by not placing nodes on top of one another if possible, but doesn't guarantee anything about the layout except that it will fall into the required viewport.
