Class ValueBaseHolder

  org.omg.CORBA.ValueBaseHolder

All Implemented Interfaces:

Streamable

public final class ValueBaseHolder
extends Object
implements Streamable

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

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

Field Summary
Serializable	value           The java.io.Serializable value held by this ValueBaseHolder object.

 

Constructor Summary
ValueBaseHolder()           Constructs a new ValueBaseHolder object with its value field initialized to 0.
ValueBaseHolder(Serializable initial)           Constructs a new ValueBaseHolder object with its value field initialized to the given java.io.Serializable.

 

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)           Marshals to output the value in the Holder.
