Class ObjectHolder

java.lang.Object

org.omg.CORBA.ObjectHolder

All Implemented Interfaces:

Streamable

public final class ObjectHolder
extends Object
implements Streamable

A holder for CORBA Object that is mapped into java org.omg.CORBA.Object. 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.

Constructor Detail

ObjectHolder

public ObjectHolder()

Constructs an instance of ObjectHolder, initializing value to 0.

ObjectHolder

public ObjectHolder(Object initial_value)

Constructs an instance of ObjectHolder, initializing value to the given org.omg.CORBA.Object.

Parameters:

initial_value - a value that will be assigned to the value field.

Method Detail

_read

public void _read(InputStream input)

Fill in the value field by reading the required data from the given stream. For org.omg.CORBA.Object, the functionality is delegated to InputStream.read_Object().

Specified by:

_read in interface Streamable

Parameters:

input - the input stream to read from.

_type

public TypeCode _type()

Returns the TypeCode, corresponding the CORBA type that is stored using this holder.

Specified by:

_type in interface Streamable

_write

public void _write(OutputStream output)

Write the value field to the given stream. For Object, the functionality is delegated to OutputStream.write_Object(Object).

Specified by:

_write in interface Streamable

Parameters:

output - the output stream to write into.
