Class LongHolder

java.lang.Object

  +--org.omg.CORBA.LongHolder
All Implemented Interfaces:
Streamable
public final class LongHolder
extends Object
implements Streamable

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

Since:
JDK1.2

Field Summary

Constructor Summary
LongHolder()
          Constructs a new LongHolder object with its value field initialized to 0.
LongHolder(long initial)

Method Summary
 void _read(InputStream input)
          Reads from input and initalizes the value in the Holder with the unmarshalled data.
 TypeCode _type()
          Returns the TypeCode object corresponding to the value held in the Holder.
 void _write(OutputStream output)
