Package org.acplt.oncrpc
Class XdrOpaque
java.lang.Object
org.acplt.oncrpc.XdrOpaque
- All Implemented Interfaces:
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.
