Interface Cache<K,V>

public interface Cache<K,V>

A Cache efficiently stores temporary objects primarily to improve an application's performance.

This interface provides an abstraction (wrapper) API on top of an underlying cache framework's cache instance (e.g. JCache, Ehcache, Hazelcast, JCS, OSCache, JBossCache, TerraCotta, Coherence, GigaSpaces, etc, etc), allowing a Okta SDK user to configure any cache mechanism they choose.

Since:

0.5.0
