Class DynUnionHelper

java.lang.Object

org.omg.DynamicAny.DynUnionHelper

public abstract class DynUnionHelper
extends Object

The helper operations for DynUnion. Following the 1.5 JDK specifications, DynUnion is always a local object, so the two methods of this helper (read(org.omg.CORBA.portable.InputStream) and write(org.omg.CORBA.portable.OutputStream, org.omg.DynamicAny.DynUnion) are not in use, always throwing MARSHAL.

DynUnionHelper

public DynUnionHelper()

Method Detail

narrow

public static DynUnion narrow(Object obj)

Cast the passed object into the DynUnion. As DynUnion is a local object, the method just uses java type cast.

Parameters:

obj - the object to narrow.

Returns:

narrowed instance.

Throws:

BAD_PARAM - if the passed object is not a DynUnion.

unchecked_narrow

public static DynUnion unchecked_narrow(Object obj)

Narrow the given object to the DynUnion. For the objects that are always local, this operation does not differ from the ordinary narrow(org.omg.CORBA.Object) (ClassCastException will be thrown if narrowing something different). See OMG issue 4158.

Parameters:

obj - the object to cast.

Returns:

the casted DynUnion.

Since:

1.5

type

public static TypeCode type()

Get the type code of the DynUnion.

insert

public static void insert(Any any,
          DynUnion that)

Insert the DynUnion into the given Any.

Parameters:

any - the Any to insert into.

that - the DynUnion to insert.

extract

public static DynUnion extract(Any any)

Extract the DynUnion from given Any.

Throws:

BAD_OPERATION - if the passed Any does not contain DynUnion.

id

public static String id()

Get the DynUnion repository id.

Returns:

"IDL:omg.org/DynamicAny/DynUnion:1.0", always.

read

public static DynUnion read(InputStream input)

This should read DynUnion from the CDR input stream, but (following the JDK 1.5 API) it does not.

Parameters:

input - a org.omg.CORBA.portable stream to read from.

Throws:

MARSHAL - always.

write

public static void write(OutputStream output,
         DynUnion value)

This should read DynUnion from the CDR input stream, but (following the JDK 1.5 API) it does not.

Parameters:

output - a org.omg.CORBA.portable stream to write into.

Throws:

MARSHAL - always.
