Interface SOAPHeader

  • All Superinterfaces:
    Element, Node, SOAPElement


    public interface SOAPHeader
    extends SOAPElement
    A representation of the SOAP header element. A SOAP header element consists of XML data that affects the way the application-specific content is processed by the message provider. For example, transaction semantics, authentication information, and so on, can be specified as the content of a SOAPHeader object.

    A SOAPEnvelope object contains an empty SOAPHeader object by default. If the SOAPHeader object, which is optional, is not needed, it can be retrieved and deleted with the following line of code. The variable se is a SOAPEnvelope object.

          se.getHeader().detachNode();
     
    A SOAPHeader object is created with the SOAPEnvelope method addHeader. This method, which creates a new header and adds it to the envelope, may be called only after the existing header has been removed.
          se.getHeader().detachNode();
          SOAPHeader sh = se.addHeader();
     

    A SOAPHeader object can have only SOAPHeaderElement objects as its immediate children. The method addHeaderElement creates a new HeaderElement object and adds it to the SOAPHeader object. In the following line of code, the argument to the method addHeaderElement is a Name object that is the name for the new HeaderElement object.

          SOAPHeaderElement shElement = sh.addHeaderElement(name);

        Creates a new SOAPHeaderElement object initialized with the specified name and adds it to this SOAPHeader object.
        Parameters:
        name - a Name object with the name of the new SOAPHeaderElement object
        Returns:
        the new SOAPHeaderElement object that was inserted into this SOAPHeader object
        Throws:
        SOAPException - if a SOAP error occurs

      • addHeaderElement

        SOAPHeaderElement addHeaderElement(QName qname)
                                    throws SOAPException
        Creates a new SOAPHeaderElement object initialized with the specified qname and adds it to this SOAPHeader object.
        Parameters:
        qname - a QName object with the qname of the new SOAPHeaderElement object

      • examineMustUnderstandHeaderElements

        Iterator examineMustUnderstandHeaderElements(String actor)
        Returns an Iterator over all the SOAPHeaderElement objects in this SOAPHeader object that have the specified actor and that have a MustUnderstand attribute whose value is equivalent to true.

        In SOAP 1.2 the env:actor attribute is replaced by the env:role attribute, but with essentially the same semantics.

        Parameters:
        actor - a String giving the URI of the actor / role for which to search
        Returns:
        an Iterator object over all the SOAPHeaderElement objects that contain the specified actor / role and are marked as MustUnderstand
        Since:
        SAAJ 1.2
        See Also:
        examineHeaderElements(java.lang.String), extractHeaderElements(java.lang.String), SOAPConstants.URI_SOAP_ACTOR_NEXT
      • examineHeaderElements

        Iterator examineHeaderElements(String actor)
        Returns an Iterator over all the SOAPHeaderElement objects in this SOAPHeader object that have the specified actor. An actor is a global attribute that indicates the intermediate parties that should process a message before it reaches its ultimate receiver. An actor receives the message and processes it before sending it on to the next actor. The default actor is the ultimate intended recipient for the message, so if no actor attribute is included in a SOAPHeader object, it is sent to the ultimate receiver along with the message body.

        In SOAP 1.2 the env:actor attribute is replaced by the env:role attribute, but with essentially the same semantics.

        Parameters:
        actor - a String giving the URI of the actor / role for which to search
        Returns:
        an Iterator object over all the SOAPHeaderElement objects that contain the specified actor / role
        See Also:
        extractHeaderElements(java.lang.String), SOAPConstants.URI_SOAP_ACTOR_NEXT
      • extractHeaderElements

        Iterator extractHeaderElements(String actor)
        Returns an Iterator over all the SOAPHeaderElement objects in this SOAPHeader object that have the specified actor and detaches them from this SOAPHeader object.

        This method allows an actor to process the parts of the SOAPHeader object that apply to it and to remove them before passing the message on to the next actor.

        In SOAP 1.2 the env:actor attribute is replaced by the env:role attribute, but with essentially the same semantics.

        Parameters:
        actor - a String giving the URI of the actor / role for which to search
        Returns:
        an Iterator object over all the SOAPHeaderElement objects that contain the specified actor / role

      • addNotUnderstoodHeaderElement

        SOAPHeaderElement addNotUnderstoodHeaderElement(QName name)
                                                 throws SOAPException
        Creates a new NotUnderstood SOAPHeaderElement object initialized with the specified name and adds it to this SOAPHeader object. This operation is supported only by SOAP 1.2.
        Parameters:
        name - a QName object with the name of the SOAPHeaderElement object that was not understood.
        Returns:

        Throws:
        SOAPException - if a SOAP error occurs.
        UnsupportedOperationException - if this is a SOAP 1.1 Header.
        Since:
