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 *
