PersistenceUnitNodepublic class PersistenceUnitNode extends DeploymentDescriptorNode | This node is responsible for reading details about one |

| Constructors Summary |
|---|
public PersistenceUnitNode()This is the default constructor which is also called from other
constructors of this class. Inside this constructor, we clear the
handlers set up by super classes' constructors because they are
not applicable in the context of PersistenceNode because
unlike standard Java EE schemas, persistence.xsd does not include
javaee_5.xsd for things like description, version etc.
// clear all the handlers set up by super classes
// because that sets up a handler for description which we are not
// interested in.
if (handlers != null) handlers.clear();

| Methods Summary |

| protected java.util.Map | getDispatchTable()This returns the dispatch table for this node.
Please note, unlike Java EE schemas persistence.xsd does not include
standard elements or attributes (e.g. version, descriptionGroupRef etc.)
from javaee_5.xsd, we don't use super classes' dispatch table.
