Class TargetPage

java.lang.Object

se.datadosen.util.TargetPage

public class TargetPage
extends Object

Speeds up page creation by allowing better parallelism. Only writes to disk if changes to contents have been detected. The old content is loaded on a background thread so page processing can occur simultaneously between constructing a TargetPage and calling writeChanges. Furthermore, this class allows the final page to be eventually written on a background thread.
