It provides content management, position management using position categories, document partition management, and change notification. In order to be notified about document changes, an object must implements <tt>IDocumentListener </tt>and must be registered with the document. <tt>Position</tt> updating in responds to a document change is performed by implementers of <tt>IDocumentPositionUpdater</tt>. Partition updating in responds to a document change is performed by implements of <tt>IDocumentPartitioner</tt>. In order to be notified about document partition changes, objects must implement <tt>IDocumentParititoningListener</tt> and must be registered with the document.</p> <p>The package contains default implementations for document position updaters and for documents. <tt>AbstractDocument</tt> uses <tt>ITextStorage</tt> for storing and managing its content and <tt>ILineTracker</tt> to maintain a line structure of its content. As defaults a gap text implementation of <tt>ITextStore</tt> is provided, together with a line tracker understanding the three standard line delimiters ("\r", "\n", "\r\n") and a line tracker which can be freely configured to consider any given set of strings as valid line delimiters. </p> <p></p> </body></html>
