javax.security.auth.message.module

Interface ClientAuthModule

All Superinterfaces:

ClientAuth

public interface ClientAuthModule
extends ClientAuth

A ClientAuthModule secures request messages, and validates received response messages.

A module implementation should assume it may be used to secure different requests as different clients. A module should also assume it may be used concurrently by multiple callers. It is the module implementation's responsibility to properly save and restore any state as necessary. A module that does not need to do so may remain completely stateless.

Every implementation of the interface must provide a public zero argument constructor.

Method Detail

initialize

void initialize(MessagePolicy requestPolicy,
                MessagePolicy responsePolicy,
                CallbackHandler handler,
                Map options)
         throws AuthException

Initialize this module with request and response message policies to enforce, a CallbackHandler, and any module-specific configuration properties.

The request policy and the response policy must not both be null.

Parameters:

requestPolicy - The request policy this module must enforce, or null.

responsePolicy - The response policy this module must enforce, or null.

handler - CallbackHandler used to request information.

options - A Map of module-specific configuration properties.

Throws:

AuthException - If module initialization fails, including for the case where the options argument contains elements that are not supported by the module.

getSupportedMessageTypes

Class[] getSupportedMessageTypes()

Get the one or more Class objects representing the message types supported by the module.

Returns:

An array of Class objects where each element defines a message type supported by the module. A module should return an array containing at least one element. An empty array indicates that the module will attempt to support any message type. This method never returns null.
