◆ translate()

void RooHistFunc::translate ( RooFit::Detail::CodeSquashContext ctx) const
overridevirtual

This function defines a translation for each RooAbsReal based object that can be used to express the class as simple C++ code.

The function adds the code represented by each class as an std::string (that is later concatenated with code strings from translate calls) to form the C++ code that AD tools can understand. Any class that wants to support AD, has to implement this function.

Parameters
[in]ctxAn object to manage auxiliary information for code-squashing. Also takes the code string that this class outputs into the squashed code through the 'addToCodeBody' function.
