Package io.github.xanthic.cache.core

Class AbstractCache<K,V>

java.lang.Object

io.github.xanthic.cache.core.AbstractCache<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
@ScheduledForRemoval(inVersion="1.0.0")
public abstract class AbstractCache<K,V>
extends Object
implements io.github.xanthic.cache.api.Cache<K,V>

Deprecated.

no longer used by Xanthic; synchronization generally should be avoided

Provides a common implementation of:

• Cache.computeIfAbsent(Object, Function)
• Cache.putIfAbsent(Object, Object)
• Cache.merge(Object, Object, BiFunction)

Subclasses ought to synchronize on getLock() for correctness.

Avoid this abstraction if the backing cache provider already provides an implementation for these methods.

Does not support null values.
