Package org.acplt.oncrpc

Class XdrOpaque

java.lang.Object
org.acplt.oncrpc.XdrOpaque
All Implemented Interfaces:
XdrAble
public class XdrOpaque extends Object implements XdrAble
Instances of the class XdrOpaque represent (de-)serializeable fixed-size opaque values, which are especially useful in cases where a result with only a single opaque value is expected from a remote function call or only a single opaque value parameter needs to be supplied.

Please note that this class is somewhat modelled after Java's primitive data type wrappers. As for these classes, the XDR data type wrapper classes follow the concept of values with no identity, so you are not allowed to change the value after you've created a value object.
