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 PerfTask.doLogic() to this method. Only the work done in PerfTask.doLogic() is 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. By default it does nothing, but tasks can implement this, moving work from PerfTask.doLogic() to this method. Only the work done in PerfTask.doLogic() is 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:

tearDown in class PerfTask

Throws:

Exception

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

getLogMessage

protected String getLogMessage(int recsCount)

Overrides:

getLogMessage in class PerfTask

setParams

public void setParams(String params)

Set the params (docSize only)

Overrides:

setParams in class PerfTask

Parameters:

params - docSize, or 0 for no limit.

supportsParams

public boolean supportsParams()

Description copied from class: PerfTask

Sub classes that support parameters must override this method to return true.

Overrides:

supportsParams in class PerfTask

Returns:

true iff this task supports command line params.
