Method Detail

doLogic

public int doLogic()
            throws Exception
Description copied from class: PerfTask
Perform the task once (ignoring repetitions specification) Return number of work items done by this task. For indexing that can be number of docs added. For warming that can be number of scanned items, etc.

Specified by:
doLogic in class PerfTask
Returns:
number of work items done by this task.
Throws:
Exception

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

getLogMessage

protected String getLogMessage(int recsCount)
Overrides:
getLogMessage in class PerfTask

setParams

public void setParams(String params)
Set the params (docid only)

Overrides:
setParams in class PerfTask
Parameters:
params - docid to delete, or -1 for deleting by delete gap settings.

supportsParams

public boolean supportsParams()
Description copied from class: PerfTask
Sub classes that supports parameters must override this method to return true.

Overrides:
supportsParams in class PerfTask
Returns:
true iff this task supports command line params.
