051    /**
052     * This class defines an API that must be implemented by scripted extensions
053     * which have the ability to process notifications about events that occur that
054     * could change the status of a user account.  For example, account status
055     * notification handlers may be used to notify the end user and/or
056     * administrators of a change to that user's account.  The kinds of events that
057     * may trigger account status notifications are defined in the
058     * {@link com.unboundid.directory.sdk.ds.types.AccountStatusNotificationType}
059     * enum, and include things like user accounts locked due to authentication
060     * failures, password expiration errors and warnings, and administrative
061     * password resets.
062     * <BR>
063     * <H2>Configuring Groovy-Scripted Account Status Notification Handlers</H2>
064     * In order to configure a scripted account status notification handler based on
065     * this API and written in the Groovy scripting language, use a command like:
066     * <PRE>
067     *      dsconfig create-account-status-notification-handler \
068     *           --handler-name "<I>{handler-name}</I>" \
069     *           --type groovy-scripted \
070     *           --set enabled:true \
071     *           --set "script-class:<I>{class-name}</I>" \
072     *           --set "script-argument:<I>{name=value}</I>"
073     * </PRE>
074     * where "<I>{handler-name}</I>" is the name to use for the account status
075     * notification handler instance, "<I>{class-name}</I>" is the fully-qualified
076     * name of the Groovy class written using this API, and "<I>{name=value}</I>"
077     * represents name-value pairs for any arguments to provide to the account
078     * status notification handler.  If multiple arguments should be provided to the
079     * account status notification handler, then the
080     * "<CODE>--set script-argument:<I>{name=value}</I></CODE>" option should be
081     * provided multiple times.
082     *
