Interface SOAPHeader

All Superinterfaces:
org.w3c.dom.Element, org.w3c.dom.Node, Node, SOAPElement
All Known Implementing Classes:
SOAPHeader

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);

Method Detail

addHeaderElement

public SOAPHeaderElement addHeaderElement(Name name)
                                   throws SOAPException
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

examineHeaderElements

public java.util.Iterator examineHeaderElements(java.lang.String actor)
Returns a list of all the SOAPHeaderElement objects in this SOAPHeader object that have the the specified actor. An actor is a global attribute that indicates the intermediate parties to whom the message should be sent. An actor receives the message and then sends it 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, the message is sent to its ultimate destination.

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

extractHeaderElements

public java.util.Iterator extractHeaderElements(java.lang.String actor)
Returns a list of all the SOAPHeaderElement objects in this SOAPHeader object that have the the specified actor and detaches them from this SOAPHeader object.

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

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

examineMustUnderstandHeaderElements

public java.util.Iterator examineMustUnderstandHeaderElements(java.lang.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.

Parameters:
actor - a String giving the URI of the actor for which to search
Returns:
an Iterator object over all the SOAPHeaderElement objects that contain the specified actor and are marked as MustUnderstand

examineAllHeaderElements

public java.util.Iterator examineAllHeaderElements()
Returns an Iterator over all the SOAPHeaderElement objects in this SOAPHeader object.

Returns:
an Iterator object over all the SOAPHeaderElement objects contained by this SOAPHeader

extractAllHeaderElements

public java.util.Iterator extractAllHeaderElements()
Returns an Iterator over all the SOAPHeaderElement objects in this SOAPHeader object and detaches them from this SOAPHeader object.

Returns:
an Iterator object over all the SOAPHeaderElement objects contained by this SOAPHeader
