The returned array should contain consecutive pairs of parameter names and parameter classes (e.g.{"Param1", String.class, "Param2", "List.class"}
).- Specified by:
getBuiltinParameters
in interfaceQueryExecuterFactory
- Returns:
- array of built-in parameter names and types associated with this query type
