Interface FactoryFinder.ObjectFactory

All Known Implementing Classes:

FactoryFinder.StandaloneObjectFactory

Enclosing class:

FactoryFinder<T>

public static interface FactoryFinder.ObjectFactory

The strategy that the FactoryFinder uses to find load and instantiate Objects can be changed out by calling the FactoryFinder.setObjectFactory(org.apache.qpid.jms.util.FactoryFinder.ObjectFactory) method with a custom implementation of ObjectFactory. The default ObjectFactory is typically changed out when running in a specialized container environment where service discovery needs to be done via the container system. For example, in an OSGi scenario.
