## Class PrincipalHolder

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

- All Implemented Interfaces:
    Streamable

  Deprecated.
  Deprecated by CORBA 2.2.

      @Deprecated
      public final class PrincipalHolder
      extends Object
      implements Streamable

  The Holder for `Principal`. For more information on Holder files, see "Generated Files: Holder Files".

  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
