Methods Summary
protected java.util.MapgetDispatchTable()
all sub-implementation of this class can use a dispatch table to map xml element to method name on the descriptor class for setting the element value.

return
the map with the element name as a key, the setter method as a value

        // no need to be synchronized for now
        Map table = super.getDispatchTable();
        table.put(TagNames.PERSISTENCE_UNIT_REF_NAME, "setName");
        table.put(TagNames.PERSISTENCE_UNIT_NAME, "setUnitName");        
        return table;
public org.w3c.dom.NodewriteDescriptor(org.w3c.dom.Node parent, java.lang.String nodeName, com.sun.enterprise.deployment.EntityManagerFactoryReferenceDescriptor descriptor)
write the descriptor class to a DOM tree and return it

param
parent node in the DOM tree
param
node name for the root element of this xml fragment
param
the descriptor to write
return
the DOM tree top node

    
        Node entityMgrFactoryRefNode = appendChild(parent, nodeName);
