Class BeanCache<Q extends Annotation,T>

java.lang.Object

org.eclipse.sisu.inject.BeanCache<Q,T>

final class BeanCache<Q extends Annotation,T>
extends 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.
