Detailed Description
Class used to access SDS structure in bulk data arguments.
This class is used internally by DRAMA2 and can be used by actions to access SDS items in bulk data arguments.
A non-threaded action (or kick message) can create one of these to access bulk data. If a Threaded actions and handlers used to process reply and kick messages, receives a bulk data argument containing an SDS item, then the SDS item is provided to the method after accessing the SDS structure by creating an object of this class.

Constructor & Destructor Documentation
|
inline |
Default constructor.
Items created this way are only suitable as a target for Move Assignment and Move Copy operations. Attempts to access the memory item will throw an exception.
| drama::BulkDataArgSds::BulkDataArgSds | ( | std::weak_ptr< Task > | theTask | ) |
Constructor - creates a BulkDataArgSds item by calling DitsBulkArgInfo() and then access the item with SDS.
Note, must be invoked only within the DRAMA message thread, in particular, as part of an action handler. This cannot be invoked in other threads.
- Parameters
-
theTask The DRAMA Task we are part of. This is passed by pointer, but BulkDataArgSds is not taking ownership of the subject object, which must continue to exist until the BulkDataSds object is destroyed.
