StreamHeader
protected StreamHeader(XMLStreamReader reader, XMLStreamBuffer mark)
Creates aStreamHeader.- 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 aStreamHeader.- Parameters:
reader- The parser that points to the start tag of the header. By the end of this method, the parser will point at the end tag of this element.- Throws:
XMLStreamException

isIgnorable
public final boolean isIgnorable(@NotNull SOAPVersion soapVersion, @NotNull Set<String> roles)
Description copied from interface:HeaderChecks 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 thoseHeaders, 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
mustUnderstandas "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 therolesset 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:
isIgnorablein interfaceHeader- Overrides:
isIgnorablein classAbstractHeaderImpl- Parameters:
soapVersion- The caller specifies the SOAP version that the pipeline is working against. Often eachHeaderimplementation already knows the SOAP version anyway, but this allows someHeaders 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.
- If this header does not have
-
getRole
@NotNull public String getRole(@NotNull SOAPVersion soapVersion)
Description copied from interface:HeaderGets 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:
getRolein interfaceHeader- Overrides:
getRolein classAbstractHeaderImpl- Parameters:
soapVersion- The caller specifies the SOAP version that the pipeline is working against. Often eachHeaderimplementation already knows the SOAP version anyway, but this allows someHeaders 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:HeaderTrue 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:
isRelayin interfaceHeader- Overrides:
isRelayin classAbstractHeaderImpl- Returns:
- false.
-
getNamespaceURI
@NotNull public String getNamespaceURI()
Description copied from interface:HeaderGets the namespace URI of this header element.- Returns:
- this string must be interned.
-
getLocalPart
@NotNull public String getLocalPart()
Description copied from interface:HeaderGets 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:HeaderGets 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
Headerimplementation doesn't have to do anything.
-
readHeader
public XMLStreamReader readHeader() throws XMLStreamException
Reads the header as aXMLStreamReader- Returns:
- must not null.
- Throws:
XMLStreamException
-
writeTo
public void writeTo(XMLStreamWriter w) throws XMLStreamException
Description copied from interface:HeaderWrites 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(javax.xml.soap.SOAPMessage saaj) throws javax.xml.soap.SOAPExceptionDescription copied from interface:HeaderWrites out the header to the given SOAPMessage.Sometimes a
Messageneeds to produce itself asSOAPMessage, in which case each header needs to turn itself into a header.- Throws:
javax.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:HeaderWrites out the header as SAX events.Sometimes a
Messageneeds 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
startPrefixMappingandendPrefixMapping, 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 toErrorHandler. If the SAX event production cannot be continued and the processing needs to abort, the code may then throw the sameSAXParseExceptionreported toErrorHandler.- Parameters:
contentHandler- TheContentHandlerthat receives SAX events.errorHandler- TheErrorHandlerthat 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 whichHeader.readAsEPR(AddressingVersion)is invoked on.- Specified by:
readAsEPRin interfaceHeader- Overrides:
readAsEPRin classAbstractHeaderImpl- 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 anWebServiceExceptionstating that fact.- Returns:
- On a successful return, this method never returns null.
- Throws:
XMLStreamException
