Constant Field Values

_parameters

protected ParameterList _parameters

The Attribute Exchange extension-specific parameters.

The openid. prefix is not part of the parameter names

Constructor Detail

AxMessage

public AxMessage()

Constructs an empty (no parameters) Attribute Exchange extension.

AxMessage

public AxMessage(ParameterList params)

Constructs an Attribute Exchange extension with a specified list of parameters.

The parameter names in the list should not contain the openid..

Method Detail

getTypeUri

public String getTypeUri()

Gets the Type URI that identifies the Attribute Exchange extension.

Specified by:

getTypeUri in interface MessageExtension

Specified by:

getTypeUri in interface MessageExtensionFactory

getParameters

public ParameterList getParameters()

Gets ParameterList containing the Attribute Exchange extension-specific parameters.

The openid. prefix is not part of the parameter names, as it is handled internally by the Message class.

The openid.ns. parameter is also handled by the Message class.

Specified by:

getParameters in interface MessageExtension

See Also:

Message

setParameters

public void setParameters(ParameterList params)

Sets the extension's parameters to the supplied list.

The parameter names in the list should not contain the openid. prefix.

Specified by:

setParameters in interface MessageExtension

Message

getParameterValue

public String getParameterValue(String name)

Gets a the value of the parameter with the specified name.

Parameters:

name - The name of the parameter, without the openid. prefix.

Returns:

The parameter value, or null if not found.

providesIdentifier

public boolean providesIdentifier()

Attribute exchange doesn't implement authentication services.

Specified by:

providesIdentifier in interface MessageExtension

Returns:

false

signRequired

public boolean signRequired()

Attribute exchange parameters are not REQUIRED to be signed.

Specified by:

signRequired in interface MessageExtension

Returns:

false

getExtension

public MessageExtension getExtension(ParameterList parameterList,
                            boolean isRequest)
                              throws MessageException

Instantiates the apropriate Attribute Exchange object (fetch / store - request / response) for the supplied parameter list.

Specified by:

getExtension in interface MessageExtensionFactory

Parameters:

parameterList - The Attribute Exchange specific parameters (without the openid. prefix) extracted from the openid message.

isRequest - Indicates whether the parameters were extracted from an OpenID request (true), or from an OpenID response.

Returns:

MessageExtension implementation for the supplied extension parameters.

Throws:

MessageException - If a Attribute Exchange object could not be instantiated from the supplied parameter list.
