Method Detail

isIgnorable

public boolean isIgnorable(com.sun.xml.ws.api.SOAPVersion soapVersion,
                           java.util.Set<java.lang.String> roles)

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 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 com.sun.xml.ws.api.message.Header

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

public java.lang.String getRole(com.sun.xml.ws.api.SOAPVersion soapVersion)

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 com.sun.xml.ws.api.message.Header

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()

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 com.sun.xml.ws.api.message.Header

Returns:

false.

getNamespaceURI

public java.lang.String getNamespaceURI()

Gets the namespace URI of this header element.

Specified by:

getNamespaceURI in interface com.sun.xml.ws.api.message.Header

Returns:

this string must be interned.

getLocalPart

public java.lang.String getLocalPart()

Gets the local name of this header element.

Specified by:

getLocalPart in interface com.sun.xml.ws.api.message.Header

Returns:

this string must be interned.

getAttribute

public java.lang.String getAttribute(java.lang.String nsUri,
                                     java.lang.String localName)

Gets the attribute value on the header element.

Specified by:

getAttribute in interface com.sun.xml.ws.api.message.Header

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.

getAttribute

public java.lang.String getAttribute(javax.xml.namespace.QName name)

Gets the attribute value on the header element.

This is a convenience method that calls into getAttribute(String, String)

Specified by:

getAttribute in interface com.sun.xml.ws.api.message.Header

Parameters:

name - Never null.

See Also:

getAttribute(String, String)

readHeader

public javax.xml.stream.XMLStreamReader readHeader()
                                            throws javax.xml.stream.XMLStreamException

Reads the header as a XMLStreamReader.

The returned parser points at the start element of this header. (IOW, XMLStreamReader.getEventType() would return XMLStreamConstants.START_ELEMENT.

Performance Expectation

For some Header implementations, this operation is a non-trivial operation. Therefore, use of this method is discouraged unless the caller is interested in reading the whole header.

Similarly, if the caller wants to use this method only to do the API conversion (such as simply firing SAX events from XMLStreamReader), then the JAX-WS team requests that you talk to us.

Messages that come from tranport usually provides a reasonably efficient implementation of this method.

Specified by:

readHeader in interface com.sun.xml.ws.api.message.Header

Returns:

must not null.

Throws:

javax.xml.stream.XMLStreamException

readAsJAXB

public <T> T readAsJAXB(Unmarshaller unmarshaller)
             throws JAXBException

Reads the header as a JAXB object by using the given unmarshaller.

Specified by:

readAsJAXB in interface com.sun.xml.ws.api.message.Header

Throws:

JAXBException

readAsJAXB

public <T> T readAsJAXB(Bridge<T> bridge,
                        BridgeContext context)
             throws JAXBException

Deprecated. Use readAsJAXB(Bridge). To be removed after JavaOne.

Throws:

JAXBException

readAsJAXB

public <T> T readAsJAXB(Bridge<T> bridge)
             throws JAXBException

Reads the header as a JAXB object by using the given unmarshaller.

Specified by:

readAsJAXB in interface com.sun.xml.ws.api.message.Header

Throws:

JAXBException

writeTo

public void writeTo(javax.xml.stream.XMLStreamWriter w)
             throws javax.xml.stream.XMLStreamException

Writes out the header.

Specified by:

writeTo in interface com.sun.xml.ws.api.message.Header

Throws:

javax.xml.stream.XMLStreamException - if the operation fails for some reason. This leaves the writer to an undefined state.

writeTo

public void writeTo(SOAPMessage saaj)
             throws SOAPException

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.

Specified by:

writeTo in interface com.sun.xml.ws.api.message.Header

Throws:

SOAPException - if the operation fails for some reason. This leaves the writer to an undefined state.

writeTo

public void writeTo(org.xml.sax.ContentHandler contentHandler,
                    org.xml.sax.ErrorHandler errorHandler)
             throws org.xml.sax.SAXException

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.

Specified by:

writeTo in interface com.sun.xml.ws.api.message.Header

Parameters:

contentHandler - The ContentHandler that receives SAX events.

errorHandler - The ErrorHandler that receives parsing errors.

Throws:

org.xml.sax.SAXException

getStringContent

public java.lang.String getStringContent()

Specified by:

getStringContent in interface com.sun.xml.ws.api.message.Header
