org.omg.DynamicAny

Class DynArrayHelper

public abstract class DynArrayHelper extends Object

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

Method Detail

extract

public static DynArray extract(Any any)

Extract the DynArray from given Any.

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

id

public static String id()

Get the DynArray repository id.

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

insert

public static void insert(Any any, DynArray that)

Insert the DynArray into the given Any.

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

narrow

public static DynArray narrow(Object obj)

Cast the passed object into the DynArray. As DynArray 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 DynArray.

read

public static DynArray read(InputStream input)

This should read DynArray 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 DynArray}.

unchecked_narrow

public static DynArray unchecked_narrow(Object obj)

Narrow the given object to the DynArray. 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 DynArray.

Since: 1.5

write

public static void write(OutputStream output, DynArray value)

This should read DynArray 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.
