Method Summary

Modifier and TypeMethod and Description
private void

private IllegalStateException
buildReactiveWrapperException(MethodParameter parameter)

protected <A extends Annotation> boolean
checkAnnotatedParamNoReactiveWrapper(MethodParameter parameter, Class<A> annotationType, BiPredicate<A, Class<?>> typePredicate)

Evaluate the Predicate on the method parameter type if it has the given annotation, nesting within java.util.Optional if necessary, but raise an IllegalStateException if the same matches the generic type within a reactive type wrapper.

protected boolean
checkParameterType(MethodParameter parameter, Predicate<Class<?>> predicate)

Evaluate the Predicate on the method parameter type or on the generic type within a reactive type wrapper.

protected boolean
checkParameterTypeNoReactiveWrapper(MethodParameter parameter, Predicate<Class<?>> predicate)

Evaluate the Predicate on the method parameter type but raise an IllegalStateException if the same matches the generic type within a reactive type wrapper.
