Class ComponentFactory

java.lang.Object
  org.jboss.cache.factories.ComponentFactory

Direct Known Subclasses:

DefaultCacheFactory, EmptyConstructorFactory, InterceptorChainFactory, NodeFactory, TransactionManagerFactory

public abstract class ComponentFactory
extends Object

Factory that creates components used internally within JBoss Cache, and also wires dependencies into the components.

The DefaultCacheFactory is a special subclass of this, which bootstraps the construction of other components. When this class is loaded, it maintains a static list of known default factories for known components, which it then delegates to, when actually performing the construction.

Since:

2.1.0
