Class WStringHolder

Implemented Interfaces:
Streamable
public class WStringHolder
extends Object
implements Streamable
A holder for CORBA wstring that is mapped into java String. This holder writes and reads differently from the StringHolder. The holders have several application areas. The end user usually sees them implementing CORBA methods where the primitive type is passed by reference. While CORBA (or, for example, C) supports this, the java does not and a wrapper class is required.

Field Summary

String
value
The String (CORBA string) value, held by this WStringHolder.

Constructor Summary

WStringHolder()
Constructs an instance of WStringHolder, initializing value to null.
WStringHolder(String initial_value)
Constructs an instance of WStringHolder, initializing value to the given String.

Method Summary

void
_read(InputStream input)
Fill in the value field by reading the required data from the given stream.
TypeCode
_type()
Returns the TypeCode, corresponding the CORBA type that is stored using this holder.
void
_write(OutputStream output)
