Class TranslogHeaderWriter

java.lang.Object

org.elasticsearch.index.translog.TranslogHeaderWriter

public final class TranslogHeaderWriter
extends Object

This class provided specialized serialization methods for translog operations. The goal is to allow direct access to the current recycler bytes stream output page and write the entire operation with a single bounds check.
