Returns the URL for a section in the specified map.

Parameters:

key - the key.

mapIndex - the map index.

Returns:

The URL.

addURLs

public void addURLs(java.util.Map urlMap)

Adds a map containing (key, URL) mappings where each key is an instance of Comparable (corresponding to the key for an item in a pie dataset) and each URL is a String representing a URL fragment.

The map is appended to an internal list...you can add multiple maps if you are working with, say, a MultiplePiePlot.

Parameters:

urlMap - the URLs (null permitted).

equals

public boolean equals(java.lang.Object o)

Tests if this object is equal to another.

Overrides:

equals in class java.lang.Object

Parameters:

o - the other object.

Returns:

A boolean.

clone

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

Returns a clone of the generator.

Specified by:

clone in interface org.jfree.util.PublicCloneable

Overrides:

clone in class java.lang.Object

Returns:
