Class NamedObjectDumpBuilder

java.lang.Object
  com.partnersoft.io.formats.dump.NamedObjectDumpBuilder

public class NamedObjectDumpBuilder
extends java.lang.Object

This class builds NamedObjectDumps using buffered streams. More efficient than the NamedObjectDump append methods. Building can be stopped and restarted; this allows having a cache of builders, stopping ones that are stale but restarting them later when needed.
