javax.swing.text
Interface AbstractDocument.Content

All Known Implementing Classes:
GapContent sample code for javax.swing.text.GapContent definition code for javax.swing.text.GapContent , StringContent sample code for javax.swing.text.StringContent definition code for javax.swing.text.StringContent
Enclosing class:
AbstractDocument sample code for javax.swing.text.AbstractDocument definition code for javax.swing.text.AbstractDocument 
public static interface AbstractDocument.Content

Interface to describe a sequence of character content that can be edited. Implementations may or may not support a history mechanism which will be reflected by whether or not mutations return an UndoableEdit implementation.
