    public class RASManager
extends java.lang.Object
implements RASConstants, RASIManager
    RASManager is a manager of RAS objects. It is an additional feature to the RAS Toolkit. That is, an application can use the RAS Tookit without a RAS Manager by creating all of the required toolkit objects in an application. This may be suitable for "smaller" applications in which the trace state and output device can be hard-coded, or passed to the application when it starts. In more complex environments, an application can be written to use a RAS Manager to acquire its RASLoggers. This generally lightens the load on the application programmer.

    The RAS Manager can also provide RAS configuration information to a graphical program, which would allow an end-user or administrator to reconfigure the RAS system -- turning specific loggers on or off, for example.

    The RAS Manager deals primarily in configuration data. That is, it must be told which RAS objects it can create, what their options are and how they are connected. When an object, such as a message logger, is requested by an application, the RAS Manager creates it from its configuration data and returns the object. Only one instance of a RAS object is created. This allows different applications, or components of a single application, to share RAS objects.

    The RAS Manager configuration is organized as one or more "groups." Groups are a way for an application to distinguish its loggers and handlers from others that may be controlled by the RAS Manager. It is recommended that each application organize its loggers into one or more RAS groups. Handlers are usually considered to be system-wide resources and are, therfore, typically contained in the "base group."

    This base group can also contain other groups. The RAS Manager thus implements a "flat tree" of groups. That is, groups may only be added to the base group. An application can impose a logical structure of groups within groups by carefully selecting group names. One way to do this is to use a naming scheme similar to Java package names. This would be very useful to a graphical program that wished to display RAS configurations to an end-user.

    An application normally only uses the getMessageLogger and getTraceLogger methods. The RAS Manager will attach to the logger any handlers which are included in the logger's configuration and any formatters which are included in the handler's configuration. The RAS Manager will search the group containing the logger and then the base group for the handler configuration information. If no handlers are included in the logger's configuration, the RAS Manager will use the set of default handlers. Formatter configurations are searched for in the same manner as handler configurations.

    In some environments, a RAS Manager may be able to get its initial configuration from persistent storage (such as a properties file or an LDAP database) and, possibly, save it there as well. This medium is represented by the RASIDataStore interface, whose restoreConfig and saveConfig methods provide this function. Two examples of a RASIDataStore are provided in this package:

    • RASDefaultDataStore assumes that no persistent store is available. The restoreConfig and saveConfig methods perform no function.
    • RASPropertyDataStore gets its configuration from a properties file of a specific format.
    If a persistent store is not available, the RAS Manager is generally not used. Without persistent storage, you can build the configuration by creating a RASBaseGroup and zero or more RASGroups and passing this to the RAS Manager through the setBaseGroup method. However, the preferred approach is to use persistent storage.

    • Constructor Detail

      • RASManager

        protected RASManager(RASIDataStore store)
        Deprecated. 
        Creates a RASManager. This method is protected to force applications to use the factory method getManager.
        Parameters:

    • Method Detail

      • getManager

        public static RASManager getManager()
        Deprecated. 
        Gets the RASManager. If the RAS Manager has already been created through a previous call to getManager, that manager is returned. Otherwise, a new manager is created and returned.

        A manager created with this method has no data store from which it can read a configuration. The addDataStore method can be used to add a data store to an existing manager.

        Returns:
        The RAS manager.
