Method Detail

getMethod

Method getMethod()

Returns the method used to create this DynamicMethodMarshaller.

copyArguments

Object[] copyArguments(Object[] args,
                       ORB orb)
                throws RemoteException

Copy the arguments as needed for this particular method. Can be optimized so that as little copying as possible is performed.

Throws:

RemoteException

readArguments

Object[] readArguments(InputStream is)

Read the arguments for this method from the InputStream. Returns null if there are no arguments.

writeArguments

void writeArguments(OutputStream os,
                    Object[] args)

Write arguments for this method to the OutputStream. Does nothing if there are no arguments.

copyResult

Object copyResult(Object result,
                  ORB orb)
           throws RemoteException

Copy the result as needed for this particular method. Can be optimized so that as little copying as possible is performed.

Throws:

RemoteException

readResult

Object readResult(InputStream is)

Read the result from the InputStream. Returns null if the result type is null.

writeResult

void writeResult(OutputStream os,
                 Object result)

Write the result to the OutputStream. Does nothing if the result type is null.

isDeclaredException

boolean isDeclaredException(Throwable thr)

Returns true iff thr's class is a declared exception (or a subclass of a declared exception) for this DynamicMethodMarshaller's method.

writeException

void writeException(OutputStream os,
                    Exception ex)

Write the repository ID of the exception and the value of the exception to the OutputStream. ex should be a declared exception for this DynamicMethodMarshaller's method.

readException

Exception readException(ApplicationException ae)

Reads an exception ID and the corresponding exception from the input stream. This should be an exception declared in this method.
