## org.omg.CORBA
Class ServiceInformationHolder

    java.lang.Object
      org.omg.CORBA.ServiceInformationHolder

All Implemented Interfaces:
  Streamable

    public final class ServiceInformationHolder

extends Object
implements Streamable

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

A Holder class for a `ServiceInformation` object that is used to store "out" and "inout" parameters in IDL methods. If an IDL method signature has an IDL `xxx` as an "out" or "inout" parameter, the programmer must pass an instance of `ServiceInformationHolder` 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 `myServiceInformationHolder` is an instance of `ServiceInformationHolder`, the value stored in its `value` field can be accessed with `myServiceInformationHolder.value`.

Field Summary
`ServiceInformation` | `value` The `ServiceInformation` value held by this `ServiceInformationHolder` object in its `value` field.

Constructor Summary
`ServiceInformationHolder()` Constructs a new `ServiceInformationHolder` object with its `value` field initialized to null.
`ServiceInformationHolder(ServiceInformation arg)` Constructs a new `ServiceInformationHolder` object with its `value` field initialized to the given `ServiceInformation` object.

Method Summary
`void` | `_read(InputStream in)` Reads unmarshalled data from the input stream `in` and assigns it to the `value` field in this `ServiceInformationHolder` object.
`TypeCode` | `_type()` Retrieves the `TypeCode` object that corresponds to the value held in this `ServiceInformationHolder` object's `value` field.
`void` | `_write(OutputStream out)` Marshals the value in this `ServiceInformationHolder` object's `value` field to the output stream `out`.
