- /// Function Definition Table syntax:

- /// - FDT ::= FDTRow [;FDTRow]*
- /// - FDTRow ::= Input => Output | Output <= Input
- /// - Input ::= ParameterName: Value [, Input]*
- /// - Output ::= [ParameterName: Value]* {halt|stop|void|nothing|Value}
- /// - Value ::= true | false | null | notnull | canbenull
- ///
- /// If method has single input parameter, it's name could be omitted.
- /// Using halt (or void/nothing, which is the same)
- /// for method output means that the methos doesn't return normally.
- /// canbenull annotation is only applicable for output parameters.
- /// You can use multiple [ContractAnnotation] for each FDT row,
- /// or use single attribute with rows separated by semicolon.
