Entities

The SmartCGMS architecture recognizes the following types of entities:

• filters - a base entity, maintains one isolated piece of work
• discrete models - generates signals with a fixed stepping
• signal models - generates signals as a result of another incoming signal level
• metrics - evaluates the differences between two signals
• solvers - optimizes parameters of a given model using a programmer-defined objective function
• approximators - approximates a discrete signal, calculates (or estimates) its derivation
• signals - containers for a set of signal levels

Each entity has its own GUID and descriptor. A single entity should be managed by a single shared object (dynamic library). The shared object that exported the entity descriptor (via the do_get_*_descriptors) must also be able to create it using appropriate factory method (do_create_*).

Some entity types must implement its respective interface. If using the C++ SDK, the interface identifiers per entity type are as follows:

• scgms::IFilter for filters
• scgms::IDiscrete_Model for discrete models
• scgms::IMetric for metrics
• scgms::IApproximator for approximators
• scgms::ISignal for signals
• signal models are not exported as entities; instead, they only manage a collection of signals (thus a signal model has a descriptor and available signals only)
• solvers are not exported as entities; instead, they are invoked using do_solve_generic call

Interface contracts, descriptor contents and implementation details are described in respective subpages.
