Class DefaultResourceCacheStrategy

java.lang.Object

com.okta.sdk.impl.ds.cache.DefaultResourceCacheStrategy

All Implemented Interfaces:

ResourceCacheStrategy

public class DefaultResourceCacheStrategy
extends Object
implements ResourceCacheStrategy

This default implementation of ResourceCacheStrategy manages reading and writing to/from a Cache. This implementation also invalidates an object's cache when DELETE and other mutating operations are called.

Key Points:

• Collection Resources are NOT cached
• Any individual Resource with a _link.self.href is cached
• The ResourceHrefResolver will be consulted if a Resource does NOT have a @{code _link.self.href} property
• A call to the cache method with a DELETE action will also remove that object from the cache
• Any @{code CREATE} or UPDATE call to the cache method, that has a _parent_ set in the ResourceDataRequest will also remove the parent from the cache

Since:

1.0
