org.omg.DynamicAny

Class DynEnumHelper

public abstract class DynEnumHelper extends Object

The helper operations for {@link DynEnum}. Following the 1.5 JDK specifications, DynEnum is always a local object, so the two methods of this helper ({@link #read} and {@link #write} are not in use, always throwing {@link MARSHAL}.

UNKNOWN: always throwing MARSHAL in read and write ensures compatibility with other popular implementations like Sun's.

Method Summary
static DynEnum	extract(Any any) Extract the DynEnum from given Any.
static String	id() Get the DynEnum repository id.
static void	insert(Any any, DynEnum that) Insert the DynEnum into the given Any.
static DynEnum	narrow(Object obj) Cast the passed object into the DynEnum.
static DynEnum	read(InputStream input) This should read DynEnum from the CDR input stream, but (following the JDK 1.5 API) it does not.
static TypeCode	type() Get the type code of the {@link DynEnum}.
static DynEnum	unchecked_narrow(Object obj) Narrow the given object to the DynEnum.
static void	write(OutputStream output, DynEnum value) This should read DynEnum from the CDR input stream, but (following the JDK 1.5 API) it does not.

Method Detail

extract

public static DynEnum extract(Any any)

Extract the DynEnum from given Any.

Throws: BAD_OPERATION if the passed Any does not contain DynEnum.

id

public static String id()

Get the DynEnum repository id.

Returns: "IDL:omg.org/DynamicAny/DynEnum:1.0", always.

insert

public static void insert(Any any, DynEnum that)

Insert the DynEnum into the given Any.

Parameters: any the Any to insert into. that the DynEnum to insert.

narrow

public static DynEnum narrow(Object obj)

Cast the passed object into the DynEnum. As DynEnum 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 DynEnum.

read

public static DynEnum read(InputStream input)

This should read DynEnum 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.

UNKNOWN: Sun throws the same exception.

type

public static TypeCode type()

Get the type code of the {@link DynEnum}.

unchecked_narrow

public static DynEnum unchecked_narrow(Object obj)

Narrow the given object to the DynEnum. For the objects that are always local, this operation does not differ from the ordinary {@link #narrow} (ClassCastException will be thrown if narrowing something different). See OMG issue 4158.

Parameters: obj the object to cast.

Returns: the casted DynEnum.

Since: 1.5

write

public static void write(OutputStream output, DynEnum value)

This should read DynEnum 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.

UNKNOWN: Sun throws the same exception.
