Package io.virtdata.processors

Class FunctionManifestProcessor

  • All Implemented Interfaces:
    javax.annotation.processing.Processor
    @SupportedOptions("title")
@SupportedSourceVersion(RELEASE_12)
@SupportedAnnotationTypes({"io.virtdata.annotations.ThreadSafeMapper","io.virtdata.annotations.PerThreadMapper"})
public class FunctionManifestProcessor
extends javax.annotation.processing.AbstractProcessor
    This annotation processor is responsible for finding all annotated functions and adding them to the manifest file for the current project. Specifically, any class annotated as ThreadSafeMapper or PerThreadMapper are recorded in 
    classes/META-INF/functions
    This operates slightly differently than the service loader facility. The point is to enumerate candidate functions without requiring them to have a no-args constructor.
