All Implemented Interfaces:

IPresentationReconciler

public class PresentationReconciler

extends Object

implements IPresentationReconciler

Standard implementation of IPresentationReconciler. This implementation assumes that the tasks performed by its presentation damagers and repairers are lightweight and of low cost. This presentation reconciler runs in the UI thread and always repairs the complete damage caused by a document change rather than just the portion overlapping with the viewer's viewport.

Usually, clients instantiate this class and configure it before using it.
