All Implemented Interfaces:

org.apache.aries.blueprint.NamespaceHandler

public class NSHandler
extends Object
implements org.apache.aries.blueprint.NamespaceHandler

This class handles the JPA namespace in blueprint xml files, it configures injection for managed persistence units and managed persistence contexts. The namespace handler also registers clients of managed persistence contexts with the GlobalPersistenceManager.

Field Summary

static String	EMPTY_UNIT_NAME_FILTER A filter to find persistence units that specify an empty name
static String	NS_URI_100 The JPA 1.0.0 namespace
static String	NS_URI_110 The JPA 1.0.0 namespace

Constructor Summary

NSHandler()

Method Summary

void	contextAvailable(org.osgi.framework.ServiceReference ref) Called when a PersistenceContextProvider is available
void	contextUnavailable(org.osgi.framework.ServiceReference ref) Called when a PersistenceContextProvider is no longer available
org.osgi.service.blueprint.reflect.ComponentMetadata	decorate(Node node, org.osgi.service.blueprint.reflect.ComponentMetadata component, org.apache.aries.blueprint.ParserContext context) Called by blueprint when we meet a JPA namespace element
Set<Class>	getManagedClasses()
URL	getSchemaLocation(String namespace)
org.osgi.service.blueprint.reflect.Metadata	parse(Element element, org.apache.aries.blueprint.ParserContext context)
