Detailed Description

template<typename ClassType, template< typename, template< typename... > class, size_t > class CheckerA, template< typename... > class ConstSignatureA, template< typename... > class StaticSignatureA, template< typename, template< typename... > class, size_t > class CheckerB, template< typename... > class ConstSignatureB, template< typename... > class StaticSignatureB>

Utility struct: sometimes we want to know if we have two functions available, and that at least one of them is const and both of them are not non-const and non-static.

If the corresponding checkers (from HAS_METHOD_FORM()) are given as CheckerA and CheckerB, and the corresponding const and static function signatures are given as ConstSignatureA, StaticSignatureA, ConstSignatureB, and StaticSignatureB, then 'value' will be true if methods with the correct names exist in the given ClassType and at least one of those two methods is const, and neither method is non-const and non-static.
