Examples of XDR

org.apache.hadoop.oncrpc.XDR
Utility class for building XDR messages based on RFC 4506.
This class maintains a buffer into which java types are written as XDR types for building XDR messages. Similarly this class can be used to get java types from an XDR request or response.
Currently only a subset of XDR types defined in RFC 4506 are supported.
