Class NamedRandomAccessObjectDump

java.lang.Object

com.partnersoft.io.formats.dump.NamedRandomAccessObjectDump

public class NamedRandomAccessObjectDump
extends java.lang.Object

This is similar to the ObjectDump, except that it is indexed by a string name rather than an integer ID. Essentially, it is WORM - you can dump an object to it, in which case the object is appended, in serialized form, with its name to the data file, and an entry added to the offset file. You can then ask for that object by index number. Not threadsafe. Write a wrapper if you need thread safety.

Compressed by default; optional constructor for uncompressed mode.
