Method Detail
setup
public void setup()
throws Exception
- Description copied from class:
PerfTask
- Task setup work that should not be measured for that specific task.
By default it does nothing, but tasks can implement this, moving work from
doLogic() to this method. Only the work done in doLogicis measured for this task.
Notice that higher level (sequence) tasks containing this task would then
measure larger time than the sum of their contained tasks.
- Overrides:
setup
in class PerfTask
- Throws:
Exception
tearDown
public void tearDown()
throws Exception
- Description copied from class:
PerfTask
- Task tearDown work that should not be measured for that specific task.

doLogic
public int doLogic()
throws Exception
- Description copied from class:

For indexing that can be number of docs added.
For warming that can be number of scanned items, etc.
