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?

Contributor guide

Research direction
Investigate the current state of lambda support in JavaCPP. Look for existing examples or documentation. If not supported, explore the possibility of wrapping Java lambdas in std::function and vice versa using JNI and C++ headers. Provide a proof of concept implementation.
