Class StrokeMap

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable
    public class StrokeMap
extends java.lang.Object
implements java.lang.Cloneable, java.io.Serializable
    A storage structure that maps Comparable instances with Stroke instances.

    To support cloning and serialization, you should only use keys that are cloneable and serializable. Special handling for the Stroke instances is included in this class.
