Detailed Description

template<class TRet, VARIABLE_ARGS>
class mel::core::Callback< TRet, VARIABLE_ARGS >

create Callback from callable

Remarks

this class dates back to the early 2000s, when no C++11 existed at all. This class is a kind of std::function. But can't be replaced because the operator == is used intensively, but is deleted in the standard for some deep reason that are not applicable here. This operator is neccesary in order to be able to compare two Callback instances, used as a base tool for unsubscribing in mel::core::CallbackSubscriptor
