Hey @Ladicek currently on vacation until 30th of August. Will review when I get back! |

Sure, no worries, and enjoy! :-) |

- renamed/moved `AnnotationInfo.MEMBER_VALUE` to `AnnotationMember.VALUE` - replaced the phrase "component type" with "element type" when speaking about arrays, because JLS uses both and each has a different meaning - removed `ContextConfig`, custom context registration is now fully handled in `MetaAnnotations` - removed unnecessarily concrete language from `@SkipIfPortableExtensionPresent` - methods in the `Types` class now have more specific return types - implementations of `AnnotationInfo`, `AnnotationMember` and `AnnotationTarget` are now required to define `equals` and `hashCode`, and are explicitly not required to use a single object to represent a single construct - the `ClassInfo` declaration is now required to return annotations `@Inherited` from a superclass, per `@Inherited` spec and CDI spec - explicitly documented that `ClassInfo` doesn't provide access to nested classes or an enclosing class, and `PackageInfo` doesn't provide access to package members - corrected some language to distinguish between generic classes (before type argument application) and parameterized types (after type argument application) - specified meaning of `MethodInfo.name` and `returnType` for constructors, mirroring what reflection does (returning the declaring class) - defined how implicit bounds are represented in `TypeVariable` and `WildcardType` - removed `ObserverInfo.id()` - usage of `Optional` was eliminated everywhere - instead of "`void` type", we now always use "`void` pseudo-type" - added `@since 4.0` tags everywhere - changed `@link` tags to `@linkplain` if the link text isn't an identifier

Can we add variants that take a ClassInfo for contextClass since this is likely to be part of the implementation

At this point (@Discovery), there's no way how to obtain a ClassInfo.

All I can think of is we can change that parameter to String, if Class is bad.

Seems it is a slippery slope and just disallowing coercion may be easier to reason about. Having said that my current implementation is doing coercion

I'd prefer disallowing coercion, but again, I can be convinced otherwise :-)

Should it not return <init> for constructors?
There was a problem hiding this comment.
It could do both. I thought class name would be better, as that's what reflection does, but I can be convinced otherwise.
