8.27.1 Trace collection points and trace information that can be collected

The following table describes the event IDs, trace collection points, and PRF trace collection levels.

Table 8‒142: Details of trace collection points in Concurrency Utilities

Event ID	No. in the figures#	Trace acquisition points	Level
0xD050	1	Entry point of the new task registration method	A
0xD051	2	Exit point of the new task registration method	A
0xD052	3	Immediately before calling a task	A
0xD053	4	Immediately after the task ends	A
0xD054	5	Entry point of the get method of the Future or ScheduledFuture object returned as a return value upon task registration	A
0xD055	6	Exit point of the get method of the Future or ScheduledFuture object returned as a return value upon task registration	A
0xD056	7	Entry point of the cancel method of the Future or ScheduledFuture object returned as a return value upon task registration	A
0xD057	8	Exit point of the cancel method of the Future or ScheduledFuture object returned as a return value upon task registration	A

Figure 8-109 shows the trace collection points when the following methods are called:

• javax.enterprise.concurrent.ManagedExecutorService#execute(Runnable)

• javax.enterprise.concurrent.ManagedScheduledExecutorService#execute(Runnable)

Figure 8-110 through Figure 8-114 show the trace collection points when the following methods are called. The trace collection points differ depending on the timing of calling the get method or the cancel method.

When the get method is called before the task finishes: Figure 8-110

When the get method is called after the task finishes: Figure 8-111

When the cancel method is called before the task execution starts: Figure 8-112

When the cancel method is called during task processing: Figure 8-113

When the cancel method is called after the task finishes: Figure 8-114
