Class CachingPropertySetFactory

java.lang.Object
  com.atlassian.user.impl.cache.properties.CachingPropertySetFactory

All Implemented Interfaces:

PropertySetFactory

public class CachingPropertySetFactory
extends Object
implements PropertySetFactory

A PropertySetFactory that wraps another PropertySetFactory and maintains a cache of its PropertySets. This prevents the need for PropertySets to be looked up repeatedly from the wrapped PropertySetFactory. Retrieved PropertySets are also wrapped in a CachedPropertySet so that individual property values are cached instead of repeatedly retrieved. Both levels of caching rewrite to the cache whenever a setter is called on a PropertySet.

The cache is keyed purely on entity name, so it assumes all entities used have unique names, even across entity types.

Since the decorated PropertySets retrieved from the underlyingPropertySetFactory are cached they must be Serializable.
