Class StrokeMap

Implemented Interfaces:
Cloneable, Serializable
public class StrokeMap
extends java.lang.Object
implements Cloneable, 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.
Since:
1.0.3

Constructor Summary

StrokeMap()
Creates a new (empty) map.

Method Summary

void
clear()
Resets the map to empty.
Object
clone()
Returns a clone of this StrokeMap.
boolean
containsKey(Comparable key)
Returns true if the map contains the specified key, and false otherwise.
boolean
equals(Object obj)
Tests this map for equality with an arbitrary object.
Stroke
getStroke(Comparable key)
Returns the stroke associated with the specified key, or null.
void
put(Comparable key, Stroke stroke)
Adds a mapping between the specified key and stroke values.
