The instance class is used for forwarding the instance of an object to invoke a property or method.
Definition instance.h:48
The method class provides several meta information about a method and can be invoked.
Definition method.h:121
bool is_valid() const noexcept
Returns true if this method is valid, otherwise false.
The parameter_info class provides several meta information about a parameter.
Definition parameter_info.h:109
The type class holds the type information for any arbitrary object.
Definition type.h:171
The variant class allows to store data of any type and convert between these types transparently.
