          public NewAnalyzerTask(PerfRunData runData)

  - ### Method Detail

    - #### createAnalyzer

          public static final Analyzer createAnalyzer(String className)
                                               throws Exception

      Throws:
        `Exception`

    - #### doLogic

          public int doLogic()
                      throws IOException

      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:
        `IOException`

    - #### setParams

          public void setParams(String params)

      Set the params (analyzerName 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.

      Analyzer names may also refer to previously defined AnalyzerFactory's.

      Example Declaration: {"NewAnalyzer" NewAnalyzer(WhitespaceAnalyzer, SimpleAnalyzer, StopAnalyzer, standard.StandardAnalyzer) >

      Example AnalyzerFactory usage:

           -AnalyzerFactory(name:'whitespace tokenized',WhitespaceTokenizer)
           -NewAnalyzer('whitespace tokenized')

      Overrides:
        `setParams` in class `PerfTask`
      Parameters:
        `params` - analyzerClassName, or empty for the StandardAnalyzer

    - #### 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.
