Description

I want to ask a question. Can Java lambda expressions be used with C++ versions of Lambda expressions (i.e. std::function)? Moreover, the "wrapping" in one direction and the other?

Research direction
Check the javacpp library's current support for wrapping Java lambdas as C++ std::function and vice versa. Review existing documentation, examples, and the source code for any lambda related mappings. The 7 comments on the issue may contain insights or partial solutions. If not supported, outline the required changes to enable such bridging.
