Might change. 47 48 EVENTS 49 50 Declard with the 'event' tag. 51 52 <value fields> can be one or more of 53 value - a simple primitive or constant type value 54 structvalue - value is a sub-struct. This type must be previously defined 55 with 'struct' 56 All these require you to declare type, field and label of the field. They also accept 57 an optional description of the field. If the meaning of the field is not obvious 58 from the label you should provide a description. If an event however is not actually 59 meant for end-users, you should probably _not_ write descriptions at all, since you 60 might just add more concepts the user has no notion of/interest in. 61 62 Events should be modeled after what conceptual process you are expressing, _NOT_ 63 from whatever data structures you might use inside the JVM for expressing a process. 64 65 66 STRUCT 67 68 Declared with the 'struct' tag. 69 70 Declares a structure type that can be used in other events. 71 72 --> 73 74 <events> 75 <event id="ThreadStart" path="java/thread_start" label="Java Thread Start" 76
