Class WildcardKey

  • final class WildcardKey
extends java.lang.Object
    Binding Key for implementations that act as "wild-cards", meaning they match against any assignable type.

    Since the wild-card type is Object and the associated qualifier may not be unique between implementations, the qualifier is saved and replaced with a unique (per-implementation) pseudo-qualifier. The original qualifier is available by casting the pseudo-qualifier to Provider and calling get().
