Examples of ILineTracker

org.eclipse.jface.text.ILineTracker

A line tracker maps character positions to line numbers and vice versa. Initially the line tracker is informed about its underlying text in order to initialize the mapping information. After that, the line tracker is informed about all changes of the underlying text allowing for incremental updates of the mapping information. It is the client's responsibility to actively inform the line tacker about text changes. For example, when using a line tracker in combination with a document the document controls the line tracker.

In order to provide backward compatibility for clients of ILineTracker, extension interfaces are used to provide a means of evolution. The following extension interfaces exist:

{@link org.eclipse.jface.text.ILineTrackerExtension} since version 3.1 introducing the conceptof rewrite sessions.

Clients may implement this interface or use the standard implementation

{@link org.eclipse.jface.text.DefaultLineTracker}or {@link org.eclipse.jface.text.ConfigurableLineTracker}.
