org.omg.DynamicAny

Class DynFixedHelper

public abstract class DynFixedHelper extends Object

The helper operations for {@link DynFixed}. Following the 1.5 JDK specifications, DynFixed 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 DynFixed	extract(Any any) Extract the DynFixed from given Any.
static String	id() Get the DynFixed repository id.
static void	insert(Any any, DynFixed that) Insert the DynFixed into the given Any.
static DynFixed	narrow(Object obj) Cast the passed object into the DynFixed.
static DynFixed	read(InputStream input) This should read DynFixed 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 DynFixed}.
static DynFixed	unchecked_narrow(Object obj) Narrow the given object to the DynFixed.
static void	write(OutputStream output, DynFixed value) This should read DynFixed from the CDR input stream, but (following the JDK 1.5 API) it does not.

Method Detail

extract

public static DynFixed extract(Any any)

Extract the DynFixed from given Any.

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

id

public static String id()

Get the DynFixed repository id.

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

insert

public static void insert(Any any, DynFixed that)

Insert the DynFixed into the given Any.

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

narrow

public static DynFixed narrow(Object obj)

Cast the passed object into the DynFixed. As DynFixed 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 DynFixed.

read

public static DynFixed read(InputStream input)

This should read DynFixed 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 DynFixed}.

unchecked_narrow

public static DynFixed unchecked_narrow(Object obj)

Narrow the given object to the DynFixed. 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 DynFixed.

Since: 1.5

write

public static void write(OutputStream output, DynFixed value)

This should read DynFixed 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.
