Package io.github.xanthic.cache.core

Class LockedAbstractCache<K,V>

java.lang.Object
io.github.xanthic.cache.core.LockedAbstractCache<K,V>
Type Parameters:
K - The type of keys that form the cache
V - The type of values contained in the cache
All Implemented Interfaces:
io.github.xanthic.cache.api.Cache<K,V>
@Deprecated public abstract class LockedAbstractCache<K,V> extends Object implements io.github.xanthic.cache.api.Cache<K,V>
Deprecated.
no longer used by Xanthic to implement any canonical cache provider
Safely implements Cache methods using ReadWriteLock.

This abstraction allows for underlying cache providers to implement the Cache interface in a thread-safe manner, even if the underlying cache does not already implement the more "exotic" write methods required by the Cache contract.

As this abstraction has a performance hit, it should be avoided if the backing cache provider already provides an implementation for these methods.

Does not support null values.
