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.
