Linear class hierarchy node (recursive case). More...

Detailed Description

template<class T, class... Args>
struct b2bits::delegate_detail::LCH< T, Args >

Linear class hierarchy node (recursive case).

Creates a linear inheritance chain from multiple callback types. Each node inherits from its callback type T and recursively from the remaining types. This allows a single object to expose multiple callback interfaces.

The hierarchy uses using-declarations to expose all overloaded operator() and assign() methods from the inheritance chain.

Template Parameters

T	Current callback type in the hierarchy
Args	Remaining callback types

#include <core/src/impl/Delegate.h>
