| 8 <p>Provides a framework for creating and manipulating text documents.</p> | |
| 9 <h3>Package Specification</h3> | |
| 10 <p><tt>IDocument</tt> is the major text | |
| 11 model abstraction. It provides content management, position management using | |
| 12 position categories, document partition management, and change notification. | |
| 13 In order to be notified about document changes, an object must implements <tt>IDocumentListener | |
| 14 </tt>and must be registered with the document. <tt>Position</tt> | |
| 15 updating in responds to a document change is performed by implementers of <tt>IDocumentPositionUpdater</tt>. | |
| 16 Partition updating in responds to a document change is performed by implements | |
| 17 of <tt>IDocumentPartitioner</tt>. In order | |
| 18 to be notified about document partition changes, objects must implement <tt>IDocumentParititoningListener</tt> | |
| 19 and must be registered with the document.</p> | |
| 20 <p>The package contains default implementations for document position updaters | |
| 21 and for documents. <tt>AbstractDocument</tt> | |
| 22 uses <tt>ITextStorage</tt> for storing | |
| 23 and managing its content and <tt>ILineTracker</tt> | |
| 24 to maintain a line structure of its content. As defaults a gap text implementation | |
| 25 of <tt>ITextStore</tt> is provided, together | |
| 26 with a line tracker understanding the three standard line delimiters ("\r", | |
| 27 "\n", "\r\n") and a line tracker which can be freely configured | |
| 28 to consider any given set of strings as valid line delimiters. </p> | |
