Class PrincipalHolder

java.lang.Object
  |
  +--org.omg.CORBA.PrincipalHolder

---

Deprecated. Deprecated by CORBA 2.2.

public final class PrincipalHolder

extends Object

implements Streamable

A container class for values of type Principal that is used to store "out" and "inout" parameters in IDL methods. If an IDL method signature has an IDL Principal as an "out" or "inout" parameter, the programmer must pass an instance of PrincipalHolder as the corresponding parameter in the method invocation; for "inout" parameters, the programmer must also fill the "in" value to be sent to the server. Before the method invocation returns, the ORB will fill in the value corresponding to the "out" value returned from the server.

If myPrincipalHolder is an instance of PrincipalHolder, the value stored in its value field can be accessed with myPrincipalHolder.value.

Since:

JDK1.2
