Class TabSet

java.lang.Object
javax.swing.text.TabSet
All Implemented Interfaces:
Serializable
public class TabSet extends Object implements Serializable
A TabSet is comprised of many TabStops. It offers methods for locating the closest TabStop to a given position and finding all the potential TabStops. It is also immutable.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans has been added to the java.beans package. Please see XMLEncoder.
