<body>
<p>Provides a framework for creating and manipulating text documents.</p>
<h3>Package Specification</h3>
<p><tt>IDocument</tt> is the major text
  model abstraction. 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 (&quot;\r&quot;,
  &quot;\n&quot;, &quot;\r\n&quot;) and a line tracker which can be freely configured
  to consider any given set of strings as valid line delimiters. </p>
