Class StrokeMap

java.lang.Object

org.jfree.chart.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.

Since:

1.0.3

public void put(java.lang.Comparable key,
                java.awt.Stroke stroke)

Adds a mapping between the specified key and stroke values.

Parameters:

key - the key (null not permitted).

stroke - the stroke.

clear

public void clear()

Resets the map to empty.

equals

public boolean equals(java.lang.Object obj)

Tests this map for equality with an arbitrary object.

Overrides:

equals in class java.lang.Object

Parameters:

obj - the object (null permitted).

Returns:

A boolean.

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Returns a clone of this StrokeMap.

Overrides:

clone in class java.lang.Object

Returns:

A clone of this instance.
