extends org.eclipse.core.runtime.jobs.Job
implements org.eclipse.jface.text.reconciler.IReconciler

Standard JFace Reconcilers, e.g. the MonoReconciler, convert an replace event into a delete and an insert DirtyRegion. This leads to significant overhead, as DRs of different types cannot be merged, and the partial parsing has to be performed for each DR in the queue. We overcome this situation by writing our own reconciler that only creates ReplaceRegions which can always be merged, such that we have to call the partial parser only once. Additionally, we simplify the reconciler by using the Job API.
