org.omg.DynamicAny
Class DynArrayHelper

java.lang.Object
  extended by org.omg.DynamicAny.DynArrayHelper

public abstract class DynArrayHelper
extends Object

The helper operations for DynArray. Following the 1.5 JDK specifications, DynArray 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.DynArray) are not in use, always throwing MARSHAL.

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 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.

DynArrayHelper

public DynArrayHelper()
Method Detail

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.

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 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 DynArray.
Since:
1.5

type

public static TypeCode type()
Get the type code of the DynArray.


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.

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.

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.

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.
