- com.github.benmanes.caffeine.cache.References.LookupKeyReference<E>

All Implemented Interfaces:

References.InternalReference<E>

Enclosing class:

References
```
static final class References.LookupKeyReference<E>
extends java.lang.Object
implements References.InternalReference<E>
```
A short-lived adapter used for looking up an entry in the cache where the keys are weakly held. This References.InternalReference implementation is not suitable for storing in the cache as the key is strongly held.

    Description copied from interface: References.InternalReference
    
    Returns this reference object's referent. If this reference object has been cleared, either by the program or by the garbage collector, then this method returns null.
    
    Specified by:
    
    get in interface References.InternalReference<E>
    
    Returns:
    
    The object to which this reference refers, or null if this reference object has been cleared
  - getKeyReference
```
public java.lang.Object getKeyReference()
```
    Description copied from interface: References.InternalReference
    
    Returns the key that is associated to the cache entry holding this reference. If the cache holds keys strongly, this is that key instance. Otherwise the cache holds keys weakly and the References.WeakKeyReference is returned.
    
    Specified by:
    
    getKeyReference in interface References.InternalReference<E>
    
    Returns:
    
    the key that is associated to the cached entry
