Class DynSequenceHelper

public abstract class DynSequenceHelper extends Object

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

Method Detail

extract

public static DynSequence extract(Any any)

Extract the DynSequence from given Any.

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

id

public static String id()

Get the DynSequence repository id.

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

insert

public static void insert(Any any, DynSequence that)

Insert the DynSequence into the given Any.

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

narrow

public static DynSequence narrow(Object obj)

Cast the passed object into the DynSequence. As DynSequence 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 DynSequence.

read

public static DynSequence read(InputStream input)

This should read DynSequence 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 DynSequence}.

unchecked_narrow

public static DynSequence unchecked_narrow(Object obj)

Narrow the given object to the DynSequence. 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 DynSequence.

Since: 1.5

write

public static void write(OutputStream output, DynSequence value)

This should read DynSequence 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.
