Issue 12571: QVT 1.0 9.* Missing query concrete syntax (qvt-rtf)
Source: Model Driven Solutions (Dr. Edward Willink, ed(at)willink.me.uk)
Nature: Uncategorized Issue
Severity: 
Summary: There is no support for queries in the QVT Core concrete syntax.


Suggest: re-use the concrete syntax of QVT Relation, except that the query
is defined at global scope and so must be qualified by the name of a
transformation defined in the same source unit.


example:


query txName::getStringSize (someString:String): Integer {
  someString -> size()
}
Resolution: Simple change. Names are left vague pending resolution of Issue 10935.
Revised Text: In 9.18 Concrete Syntax add (NB TopLevel introduced by Issue 10942)
TopLevel ::= (Transformation | Mapping | Query)*
Query ::= 'query' QueryName '(' [ ParamDeclaration (',' ParamDeclaration)*] ')'
':' TypeDeclaration (';' | '{' QueryOCLExpr '}')
ParamDeclaration ::= ParameterName ':' TypeDeclaration
