Description

template<typename TY>
class lib::diff::anonymous_namespace{tree-mutator-diffmutable-binding.hpp}::Can_retrieve_and_compare_ID< TY >

Metaprogramming helper to detect if the given target class allows us to build a default »Matcher« automatically.

(The »Matcher« is used to determine the applicability of a given diff verb to this target object)

Note

we directly probe the desired functionality: can we equality compare a given GenNode::ID (from the diff) with this type's object ID?

See also

duck-detector.hpp for explanation of this technique
