Package io.vavr.match

Class PatternsProcessor

  • All Implemented Interfaces:
    javax.annotation.processing.Processor
    public class PatternsProcessor
extends javax.annotation.processing.AbstractProcessor
    A code generator for Vavr structural pattern matching patterns.

    Note:

    If javac complains [WARNING] No processor claimed any of these annotations: ... we need to provide the compiler arg -Xlint:-processing.

    See JDK-6999068 bug.
