Detailed Description

Helper class for managing the service context list information.

This class is used to manipulate and access the service context list that is passed around with every GIOP request/reply. The definition of the service context list is simply a sequence of the following structures: typedef unsigned long ServiceId; struct ServiceContext { ServiceId context_id; sequence <octet> context_data; }; typedef sequence <ServiceContext> ServiceContextList;

the real motivation behind this class is to consolidate all the marshalling and unmarshalling information pertaining to service context list

Note: Somewhere down the line we may want to use this class for fast access to the info that we need from the Service Context List.

= Marshaling and demarshaling the list

int TAO_Service_Context::get_context ( IOP::ServiceContext & context ) const

Get a copy of the context identified by <context.context_id>, return 0 if the component is not present.

int TAO_Service_Context::get_context	(	IOP::ServiceId	id,
		const IOP::ServiceContext **	context
	)		const

Get a reference to a context identified by id, return 0 if the component is not present.

int TAO_Service_Context::get_context	(	IOP::ServiceId	id,
		IOP::ServiceContext_out	context
	)

Get a copy of the Service Context corresponding to the given ServiceId. The caller owns the returned Service Context.

Returns: 0 If a Service Context with the given ServiceId doesn't exist.

Helper methods to implement get_context()

bool TAO_Service_Context::is_service_id ( IOP::ServiceId id )

Is the id available in the underlying service context list? If so return true, else return false

TAO_Service_Context& TAO_Service_Context::operator= ( const TAO_Service_Context & )

private

IOP::ServiceContextList & TAO_Service_Context::service_info ( void )

Return the underlying service context list.

const IOP::ServiceContextList & TAO_Service_Context::service_info ( void ) const

Note: This method is only for backward comptiblity. We need to get this removed once RT folks have their service addition info done through this interface

void TAO_Service_Context::set_context ( const IOP::ServiceContext & context )

= Generic components

Insert the component into the list, making a copy of the octet sequence.

int TAO_Service_Context::set_context	(	const IOP::ServiceContext &	context,
		CORBA::Boolean	replace
	)

Insert the component into the list, making a copy of the octet sequence. Search the list before insertion so that the insertion does not cause a duplicate context to be in the list. If the replace flag is true, update the specified context. Return 0 if the component was present and the replace flag was not set to true.

void TAO_Service_Context::set_context ( IOP::ServiceContext & context )

Insert the component into the list, but efficiently stealing the contents of the octet sequence.

void TAO_Service_Context::set_context	(	IOP::ServiceId	id,
		TAO_OutputCDR &	cdr
	)

Set the context from the CDR stream and add that to the service Context list

void TAO_Service_Context::set_context	(	IOP::ServiceContext &	context,
		TAO_OutputCDR &	cdr
	)

Set the context from the CDR stream and return the context back to the caller. Does not modify the underlying service context list.

void TAO_Service_Context::set_context_i ( const IOP::ServiceContext & context )
