# Class EventType

Contains event type constants. The decision to use class and not enumeration is dictated by allowing users to create their own events and/or event types which would be impossible with enumerations.

Note that this interface defines not only individual type constants, but arrays of types as well to be conveniently used with IEvents methods.

NOTE: all types in range from 1 to 1000 are reserved for internal Ignite events and should not be used by user-defined events.
