| Events in the JVM are by default timed (it's more common) |
| Perhaps a little strange. Might change. |
| |
| EVENTS |
| |
| Declard with the 'event' tag. |
| |
| <value fields> can be one or more of |
| value - a simple primitive or constant type value |
| structvalue - value is a sub-struct. This type must be previously defined |
| with 'struct' |
| All these require you to declare type, field and label of the field. They also accept |
| an optional description of the field. If the meaning of the field is not obvious |
| from the label you should provide a description. If an event however is not actually |
| meant for end-users, you should probably _not_ write descriptions at all, since you |
| might just add more concepts the user has no notion of/interest in. |
| |
| Events should be modeled after what conceptual process you are expressing, _NOT_ |
| from whatever data structures you might use inside the JVM for expressing a process. |
| |
| |
| STRUCT |
| |
| Declared with the 'struct' tag. |
| |
| Declares a structure type that can be used in other events. |
