      protected StreamHeader(XMLStreamReader reader, com.sun.xml.stream.buffer.XMLStreamBuffer mark)
      Creates a StreamHeader.
      Parameters:
      reader - The parser pointing at the start of the mark. Technically this information is redundant, but it achieves a better performance.
      mark - The start of the buffered header content.
    • StreamHeader

      protected StreamHeader(XMLStreamReader reader) throws XMLStreamException
      Creates a StreamHeader.

    • isIgnorable

      public final boolean isIgnorable(@NotNull SOAPVersion soapVersion, @NotNull Set<String> roles)
      Description copied from interface: Header
      Checks if this header is ignorable for us (IOW, make sure that this header has a problematic "mustUnderstand" header value that we have to reject.)

      This method is used as a part of the mustUnderstanx processing. At the end of the processing, the JAX-WS identifies a list of Headers that were not understood. This method is invoked on those Headers, to verify that we don't need to report an error for it.

      specifically, this method has to perform the following tasks:

      • If this header does not have mustUnderstand as "1" nor "true", then this method must return true.
      • Otherwise, check the role attribute (for SOAP 1.2) or the actor attribute (for SOAP 1.1). When those attributes are absent, the default values have to be assumed. See Header.getRole(SOAPVersion) for how the values are defaulted. Now, see if the roles set contains the value. If so, this method must return false (indicating that an error is in order.)
      • Otherwise return true (since we don't play the role this header is intended for.)
      Specified by:
      isIgnorable in interface Header
      Overrides:
      isIgnorable in class AbstractHeaderImpl
      Parameters:
      soapVersion - The caller specifies the SOAP version that the pipeline is working against. Often each Header implementation already knows the SOAP version anyway, but this allows some Headers to avoid keeping it. That's why this redundant parameter is passed in.
      roles - The set of role values that the current JAX-WS pipeline is assuming. Note that SOAP 1.1 and SOAP 1.2 use different strings for the same role, and the caller is responsible for supplying a proper value depending on the active SOAP version in use.
      Returns:
      true if no error needs to be reported. False if an error needs to be raised. See the method javadoc for more discussion.
    • getRole

      @NotNull public String getRole(@NotNull SOAPVersion soapVersion)
      Description copied from interface: Header
      Gets the value of the soap:role attribute (or soap:actor for SOAP 1.1).

      If the attribute is omitted, the value defaults to SOAPVersion.implicitRole.

      Specified by:
      getRole in interface Header
      Overrides:
      getRole in class AbstractHeaderImpl
      Parameters:
      soapVersion - The caller specifies the SOAP version that the pipeline is working against. Often each Header implementation already knows the SOAP version anyway, but this allows some Headers to avoid keeping it. That's why this redundant parameter is passed in.
      Returns:
      never null. This string need not be interned.
    • isRelay

      public boolean isRelay()
      Description copied from interface: Header
      True if this header is to be relayed if not processed. For SOAP 1.1 messages, this method always return false.

      IOW, this method returns true if there's @soap:relay='true' is present.

      Implementation Note

      The implementation needs to check for both "true" and "1", but because attribute values are normalized, it doesn't have to consider " true", " 1 ", and so on.

      Specified by:
      isRelay in interface Header
      Overrides:
      isRelay in class AbstractHeaderImpl
      Returns:
      false.
    • getNamespaceURI

      @NotNull public String getNamespaceURI()
      Description copied from interface: Header
      Gets the namespace URI of this header element.
      Returns:
      this string must be interned.
    • getLocalPart

      @NotNull public String getLocalPart()
      Description copied from interface: Header
      Gets the local name of this header element.
      Returns:
      this string must be interned.
    • getAttribute

      public String getAttribute(String nsUri, String localName)
      Description copied from interface: Header
      Gets the attribute value on the header element.
      Parameters:
      nsUri - The namespace URI of the attribute. Can be empty.
      localName - The local name of the attribute.
      Returns:
      if the attribute is found, return the whitespace normalized value. (meaning no leading/trailing space, no consequtive whitespaces in-between.) Otherwise null. Note that the XML parsers are responsible for whitespace-normalizing attributes, so Header implementation doesn't have to do anything.
    • readHeader

      public XMLStreamReader readHeader() throws XMLStreamException
      Reads the header as a XMLStreamReader
      Returns:
      must not null.
      Throws:
      XMLStreamException
    • writeTo

      public void writeTo(XMLStreamWriter w) throws XMLStreamException
      Description copied from interface: Header
      Writes out the header as a fragment.
      Throws:
      XMLStreamException - if the operation fails for some reason. This leaves the writer to an undefined state.
    • writeTo

      public void writeTo(jakarta.xml.soap.SOAPMessage saaj) throws jakarta.xml.soap.SOAPException
      Description copied from interface: Header
      Writes out the header to the given SOAPMessage.

      Sometimes a Message needs to produce itself as SOAPMessage, in which case each header needs to turn itself into a header.

      Throws:
      jakarta.xml.soap.SOAPException - if the operation fails for some reason. This leaves the writer to an undefined state.
    • writeTo

      public void writeTo(ContentHandler contentHandler, ErrorHandler errorHandler) throws SAXException
      Description copied from interface: Header
      Writes out the header as SAX events.

      Sometimes a Message needs to produce SAX events, and this method is necessary for headers to participate to it.

      A header is responsible for producing the SAX events for its part, including startPrefixMapping and endPrefixMapping, but not startDocument/endDocument.

      Note that SAX contract requires that any error that does NOT originate from ContentHandler (meaning any parsing error and etc) must be first reported to ErrorHandler. If the SAX event production cannot be continued and the processing needs to abort, the code may then throw the same SAXParseException reported to ErrorHandler.

      Parameters:
      contentHandler - The ContentHandler that receives SAX events.
      errorHandler - The ErrorHandler that receives parsing errors.
      Throws:
      SAXException
    • readAsEPR

      @NotNull public WSEndpointReference readAsEPR(AddressingVersion expected) throws XMLStreamException
      Creates an EPR without copying infoset. This is the most common implementation on which Header.readAsEPR(AddressingVersion) is invoked on.
      Specified by:
      readAsEPR in interface Header
      Overrides:
      readAsEPR in class AbstractHeaderImpl
      Parameters:
      expected - The version of the addressing used to parse the EPR. If the actual infoset and this doesn't agree, then you'll get an WebServiceException stating that fact.
      Returns:
      On a successful return, this method never returns null.
      Throws:
      XMLStreamException
    • processHeaderAttributes

      protected abstract com.sun.istack.FinalArrayList<StreamHeader.Attribute> processHeaderAttributes(XMLStreamReader reader)
