 * This interface is implemented by the factory class for every
 * plugin mechanism. The GSSManager locates an implementation of this
 * interface by querying the security providers installed on the
 * system. For a provider to support a mechanism defined by Oid x.y.z,
 * the provider master file would have to contain a mapping from the
 * property "GssApiMechanism.x.y.z" to an implementation class that serves
 * as the factory for that mechanism.
 * <p>
 * e.g., If a provider master file contained the a mapping from the
 * property "GssApiMechanism.1.2.840.113554.1.2.2" to the class name
 * "com.foo.krb5.Krb5GssFactory", then the GSS-API framework would assume
 * that com.foo.krb5.Krb5GssFactory implements the MechanismFactory
 * interface and that it can be used to obtain elements required by for
 * supporting this mechanism.
