Class TypeBindings.TypeParamStash

  • Enclosing class:
    TypeBindings
    static class TypeBindings.TypeParamStash
extends java.lang.Object
    Helper class that contains simple logic for avoiding repeated lookups via Class.getTypeParameters() as that can be a performance issue for some use cases (wasteful, usually one-off or not reusing mapper). Partly isolated to avoid initialization for cases where no generic types are used.
