Class ShutdownTask

  • All Implemented Interfaces:
    java.io.Serializable

    @NotMutable
    @ThreadSafety(level=COMPLETELY_THREADSAFE)
    public final class ShutdownTask
    extends Task
    This class defines a Directory Server task that can be used to shut down or restart the server.
    NOTE: This class, and other classes within the com.unboundid.ldap.sdk.unboundidds package structure, are only supported for use against Ping Identity, UnboundID, and Nokia/Alcatel-Lucent 8661 server products. These classes provide support for proprietary functionality or for external specifications that are not considered stable or mature enough to be guaranteed to work in an interoperable way with other types of LDAP servers.

    The properties that are available for use with this type of task include:
    • A flag that indicates whether to shut down the server or to perform an in-core restart (in which the server shuts down and restarts itself within the same JVM).
    • An optional message that can be used to provide a reason for the shutdown or restart.

      • ShutdownTask

        public ShutdownTask()
        Creates a new uninitialized shutdown task instance which should only be used for obtaining general information about this task, including the task name, description, and supported properties. Attempts to use a task created with this constructor for any other reason will likely fail.

        public java.util.List<TaskPropertygetTaskSpecificProperties()
        Retrieves a list of task-specific properties that may be provided when scheduling a task of this type. This method should be overridden by subclasses in order to provide an appropriate set of properties.
        Overrides:
        getTaskSpecificProperties in class Task
        Returns:
        A list of task-specific properties that may be provided when scheduling a task of this type.

Task properties which do not have any values will be included in the map with an empty value list.

        Note that subclasses which have additional task properties should override this method and return a map which contains both the property values from this class (obtained from super.getTaskPropertyValues() and the values of their own task-specific properties.
        Overrides:
        getTaskPropertyValues in class Task
        Returns:
