Remarks

An event type defines the structure of CEP events. A CEP stream is always of one specific event type and thus can contain only events with this structure. An event type is based on a CLR struct or class and as such implicitly registered with an application when necessary. The registration of a LINQ query template object in an application, for instance, implicitly creates the input and output event types in that application, based on the CLR types that are input and result of the LINQ statement.

An event type contains a list of atomic fields, which in turn are of a certain CEP event type.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
