Class NamespaceHelper

java.lang.Object

com.sun.xml.rpc.processor.modeler.j2ee.NamespaceHelper

public class NamespaceHelper
extends Object

Helper class used to convert a QName from a xsd:QName string in an XML schema instance. The xsd:QName string is of the form prefix:localpart, and the mapping of prefix to a real namesapce may be defined at any level in the traversal of the XML instance. There, this class is intended to be used as follows:
When traversing a new child node BaseType, the push() method must be called to allow the NamespaceHelper to fetch any new prefix and namespace declaration in the child node. When done with visiting the child node, the pop() method must be called to revert back to previous settings.
