Dynamically Generated Compiled Code

Hi folks,

Is there a way to dynamically generate compiled code? I am after what can be done with reflection but without the performance cost. It seems logical that a good way to accomplish the goal is to compile code at run-time.

Thoughts? Successes? Ideas?

Sounds like an interpreter... Performance cost will be present.

Using reflection is an interpreter and does come with a performance cost. What I am looking for is potentially a way to construct Java code on the fly and pass it to something that will translate it into byte-code for later use... or anything that comes close to that.

Isn't that the same thing that already happens, though?

You're right that does happen. The part that I failed to mention is that I would want to retain that compiled code and potentially execute it many times without having to reinterpret it. Hope that clarifies things a touch.

Found what I was looking for:
