A codat can represent a file, a class file, the saved state of an application, a loadable C library. Codats are handled transparently by the JXTA platform, and are used as placeholders for any type of data. Codats holds a Document that represent the data that they hold.</p> <p>Each Codat is assigned a unique codat id that enables canonical references to be made to the codat in the context of a specific peer group. A CodatID is formed by the conjuction of a PeerGroupID, a randomly chosen value that has a high probability of being unique, and an optional SHA1 cryptographic hash of the codat contents. The Id is the unique Id for this Codat within the JXTA world. Some codats may not hold a document. In that case the CodatId is constructed without the document hash value.<P><P><DL><DT><B>See Also:</B><DD><A HREF="../../../net/jxta/codat/Codat.html" title="class in
