Hello all,
What is the best way to check if a type T is EqualityComparable?
Essentially, I would need a is_equality_comparable<> metafunction:
struct mytype {};
is_equality_comparable<int>::value // true is_equality_comparable<mytype>::value // false
Can I re-use the boost::EqualityComparable concept to implement is_equality_comparable<>? Or, shall I just try to use introspection-SFINAE techniques?
Thanks in advance. --Lorenzo
I think the (relatively) recently-reviewed TypeTraits Extension by Frederic Bron has what you're looking for, although I have no idea what the name of the particular metafunction is at the moment :) has_operator_equals?
can_call_equal from TypeTraits Extension worked. Thanks to all for your suggestions. --Lorenzo -- View this message in context: http://boost.2283326.n4.nabble.com/concept-EqualityComparable-metafunction-t... Sent from the Boost - Dev mailing list archive at Nabble.com.
