Module io.helidon.codegen

Package io.helidon.codegen

package io.helidon.codegen

Code generation and processing support.

The main type to start with is Codegen, that is responsible for discovering all extensions on the classpath, to understand what annotations they are interested in, and then invoking them as needed. This type is expected to be called from an annotation processor, Maven plugin, or a command line tool (or any other tool capable of analyzing sources or byte code and/or generating new types.
