TClingCallFunc Class Reference

Emulation of the CINT CallFunc class.

The CINT C++ interpreter provides an interface for calling functions through the generated wrappers in dictionaries with the CallFunc class. This class provides the same functionality, using an interface as close as possible to CallFunc but the function metadata and calling service comes from the Cling C++ interpreter and the Clang C++ compiler, not CINT.
