Class CodeGenFiler

java.lang.Object
io.helidon.inject.tools.CodeGenFiler
public class CodeGenFiler extends Object
This class is used to generate the source and resources originating from either annotation processing or maven-plugin invocation. It also provides a circuit breaker in case the filer should be disabled from actually writing out source and resources, and instead will use the filer's messager to report what it would have performed (applicable for apt cases).
