See the YGOR Fundamentals documentation for further details. The way one interacts with a manager is through parameters, samplers, and manager methods. The set of parameters and their values which completely describe how one can specify all the options for a manager are flagged as being primary parameters. The way one interacts with a manager is through parameters, samplers, and manager methods. Samplers provide a continuous stream of data values much like a power meter, frequency counter, or volt meter.
Registries accept sampler values continuously for purposes of creating log files.
For example, whenever a CLEO application displays a monitor component, it establishes a connection to the accessor to get a stream of sampled values which are displayed in the widget on the screen. Synchronous Managers Managers come in two flavors, synchronous and asynchronous. Synchronous managers are those that can be scheduled to work in tune to what other managers are doing. All backend managers, for example, are synchronous since they shouldn't take data unless the telescope manager decides the telescope is on source.
