Class BeanCache<Q extends java.lang.annotation.Annotation,​T>

  • All Implemented Interfaces:
    java.io.Serializable
    final class BeanCache<Q extends java.lang.annotation.Annotation,​T>
extends java.util.concurrent.atomic.AtomicReference<java.lang.Object>
    Atomic cache mapping Bindings to BeanEntrys; optimized for common case of single entries.

    Uses == instead of equals to compare Bindings because we want referential equality.
