Header

Direct Known Subclasses:

public abstract class AbstractHeaderImpl

Partial default implementation of Header.

Method Summary

String	getAttribute(QName name) Gets the attribute value on the header element.
String	getRole(SOAPVersion soapVersion) Gets the value of the soap:role attribute (or soap:actor for SOAP 1.1).
String	getStringContent() Used to obtain value XYZ from a header that looks like "<header>XYZ</header>".
boolean	isIgnorable(SOAPVersion soapVersion, Set<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.)
boolean	isRelay() True if this header is to be relayed if not processed.
protected boolean	parseBool(String value) Parses a string that looks like xs:boolean into boolean.
WSEndpointReference	readAsEPR(AddressingVersion expected) Default implementation that copies the infoset.
<T> T	readAsJAXB(com.sun.xml.bind.api.Bridge<T> bridge) Deprecated.
<T> T	readAsJAXB(com.sun.xml.bind.api.Bridge<T> bridge, com.sun.xml.bind.api.BridgeContext context) Deprecated.
<T> T	readAsJAXB(Unmarshaller unmarshaller) Reads the header as a JAXB object by using the given unmarshaller.

Method Detail

readAsJAXB

public final <T> T readAsJAXB(com.sun.xml.bind.api.Bridge<T> bridge,
                              com.sun.xml.bind.api.BridgeContext context)
                   throws JAXBException

Deprecated.

Throws:

JAXBException

readAsJAXB

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

Description copied from interface: Header

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

Specified by:

readAsJAXB in interface Header

Throws:

JAXBException

readAsJAXB

public <T> T readAsJAXB(com.sun.xml.bind.api.Bridge<T> bridge)
             throws JAXBException

Deprecated.

Description copied from interface: Header

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

Specified by:

readAsJAXB in interface Header

Throws:

JAXBException

readAsJAXB

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

Description copied from interface: Header

Reads the header as a data-bond object

Specified by:

readAsJAXB in interface Header

Throws:

JAXBException

readAsEPR

public WSEndpointReference readAsEPR(AddressingVersion expected)
                              throws XMLStreamException

Default implementation that copies the infoset. Not terribly efficient.

Specified by:

readAsEPR in interface Header

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

isIgnorable

public 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

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

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

Returns:

false.

getAttribute

public String getAttribute(QName name)

Description copied from interface: Header

Gets the attribute value on the header element.

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

Specified by:

getAttribute in interface Header

Parameters:

name - Never null.

See Also:

Header.getAttribute(String, String)

parseBool

protected final boolean parseBool(String value)

Parses a string that looks like xs:boolean into boolean. This method assumes that the whilespace normalization has already taken place.

getStringContent

public String getStringContent()

Description copied from interface: Header

Used to obtain value XYZ from a header that looks like "<header>XYZ</header>". The primary use of this header for now is to access certain Addressing headers quickly.

Specified by:

getStringContent in interface Header

Returns:

Can be empty but always non-null.
