This fact contains the information, what type parameters a class, method or constructor has. Facts for classes, methods and constructors do not contain information about their type parameters.

#id: classT, methodT, constructorT
the ID of the class, method or constructor.

[#paramRef_1, …]: typeParamT
list of IDs of type parameters that belong to the class, method or constructor.

typeParamT(#typeparam, #meth, 'T', [#typeref]).
