Generic interface for the DII invocation object visible.

Constructor & Destructor Documentation

TAO::DII_Invocation_Adapter::DII_Invocation_Adapter	(	CORBA::Object *	target,
		Argument **	args,
		int	arg_number,
		const char *	operation,
		size_t	op_len,
		CORBA::ExceptionList *	exception,
		CORBA::Request *	r,
		Invocation_Mode	mode = `TAO_DII_INVOCATION`
	)

The only constructor used by the IDL compiler and only way to create this adapter.

Parameters:

	target	Points to the object on which this invocation is being invoked.
	args	Array of pointers to the argument list in the operation declaration. this includes the return, inout and out arguments.
	arg_number	Number of arguments in the above array. This is the number of elements in the above array.
	operation	The name of the operation being invoked.
	op_len	Number of characters in the operation name. This is an optimization which helps us to avoid calling strlen () while creating a message format.
	mode	Invocation mode. This information is also available in the IDL file and in the generated code.

void TAO::DII_Invocation_Adapter::invoke	(	TAO::Exception_Data *	ex,

Invoke the target.

Make a collocated call.

This method creates an object that takes care of making collocated invocations and calls invoke () on it. If the invoke () returns with a location forwarded reply we return a restart

Parameters:

	stub	The stub object on which the invocation is made.
	details	The operations details of the operation that is being invoked.

	)			`[protected, virtual]`

Helper method to make a two way invocation.

This method creates a synchronous twoway invocation object to which the actual task of request handling is delegated. Once the invocation returns this method checks whether the request is forwarded to a new location.

Reimplemented from TAO::Invocation_Adapter.

Reimplemented in TAO::DII_Asynch_Invocation_Adapter.
