Examples of org.apache.ws.policy.util.StAXPolicyWriter

org.apache.ws.policy.util.StAXPolicyWriter
StAXPolicyWriter implements PolicyWriter and provides different methods to create a Policy object. It uses StAX as its underlying mechanism to create XML elements. @author Sanka Samaranayake (sanka@apache.org)
