javax.swing.text

Class PlainDocument

  • All Implemented Interfaces:
    Serializable, Document

    public class PlainDocument
    extends AbstractDocument
    A plain document that maintains no character attributes. The default element structure for this document is a map of the lines in the text. The Element returned by getDefaultRootElement is a map of the lines, and each child element represents a line. This model does not maintain any character level attributes, but each line can be tagged with an arbitrary set of attributes. Line to offset, and offset to line translations can be quickly performed using the default root element. The structure information of the DocumentEvent's fired by edits will indicate the line structure changes.

    The default content storage management is performed by a gapped buffer implementation (GapContent). It supports editing reasonably large documents with good efficiency when the edits are contiguous or clustered, as is typical.

    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 JavaBeansTM has been added to the java.beans package. Please see XMLEncoder.
