| <p>Provides a framework for creating and manipulating text documents.</p> |
| <h2>Package Specification</h2> |
| <p><code>IDocument</code> 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 <code>IDocumentListener |
| </code>and must be registered with the document. <code>Position</code> |
| updating in responds to a document change is performed by implementers of <code>IDocumentPositionUpdater</code>. |
| Partition updating in responds to a document change is performed by implements |
| of <code>IDocumentPartitioner</code>. In order |
| to be notified about document partition changes, objects must implement <code>IDocumentParititoningListener</code> |
| and must be registered with the document.</p> |
| <p>The package contains default implementations for document position updaters |
| and for documents. <code>AbstractDocument</code> |
| uses <code>ITextStorage</code> for storing |
| and managing its content and <code>ILineTracker</code> |
| to maintain a line structure of its content. As defaults a gap text implementation |
| of <code>ITextStore</code> 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><code>ITextViewer</code> defines the concept of a document based, editiable viewer. |
| <code>ITextViewer</code> offers the following functionality: </p> |
| <ul> |
| <li> |
| present a document</li> |
| |
| <li> |
| event consumption (<code>IEventConsumer</code>)</li> |
| |
| <li> |
| viewport tracking and notification (<code>IIViewportListener</code>)</li> |
| |
| <li> |
| change notification (<code>ITextListener</code>, <code>ITextInputListener</code>)</li> |
| |
| <li> |
| listeners (combined view/model notification, input document)</li> |
| |
| <li> |
| standard text editing functions plus text hover support</li> |
| |
| <li> |
| visual region support</li> |
| </ul> |
| |
| An <code>ITextViewer</code> supports the following plug-ins |
| <ul> |
| <li> |
| <code>IUndoManager</code> for the undo/redo mechanism</li> |
| |
| <li> |
| <code>IDoubleClickStrategy</code> for partition type specific behavior on mouse |
| double click</li> |
| |
| <li> |
| <code>IAutoIndentStrategy</code> for content type specific behavior on |
| inserting a line break</li> |
| |
| <li> |
| <code>ITextHover</code> for content type specific behavior when overing over |
| text</li> |
| </ul> |
| The package provides default implementations for all these interfaces. |
