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:

IOException

setParams

public void setParams(String params)

Set the params (analyzerClassName only), Comma-separate list of Analyzer class names. If the Analyzer lives in org.apache.lucene.analysis, the name can be shortened by dropping the o.a.l.a part of the Fully Qualified Class Name.

Returns:

true iff this task supports command line params.
