Description

Is your feature request related to a problem? Please describe.

Is it possible to have server and client side, a MAP attribut to allow user to pass headers ? And server to retrieve them directly from method signature ?
I'm using the java generator.

Describe the solution you'd like

I want to be able to ask codeGen to add a header parameter in the method generated in java for a path.

Research direction

Start by locating the Java generator entry points for server and client method generation and inspect how operation headers are currently represented. The issue names no files or tests; done would require a defined, tested way for generated methods to accept header maps and for server methods to retrieve them.
