Summary

0006769: Move parameters from DataInstance to DataSet

Description

(Formal) parameters serve only one purpose, they specify a named feature of containing entity that can accept/prvoide a value (and possibly details about the nature of the value, like its multipilicity). In statically typed languages this information is contained in types. In duck typed languages this information is not present, arguments are assigned without predefined parameters (fields). Both from logical and practical perspective, there is no need for parameter definitions in DataInstances (although there’s an analogy with TTCN-3 parameterized templates). If strong typing is needed, then parameters should be defined in DataSets (or an entity playing their role in updated meta-model).

If strong typing is not needed, then DataInstance parameters should be treated as arguments. Data in TDL is abstract and any predefined values associated with instances should be implicit and not defined in TDL. Therefore, DataInstance paramters should be excluded.

Solution is to introduce parameters to DataSets and remove parameters from DataInstance. DataSet parameters are optional.

Example.

Current:

dataset SequenceNumber {1, 2, 3}

dataset Message {datainstance Request(1), datainstance Response(2), datainstance Post(3)}

interaction <source> <target> Request(1)

Proposed:

dataset SequenceNumber {1, 2, 3}

dataset Message (SequenceNumber) {datainstance Request, datainstance Response, datainstance Post}

interaction <source> <target> Request(1)
