## Class ReadTokensTask

- java.lang.Object
- - org.apache.lucene.benchmark.byTask.tasks.PerfTask
  - - org.apache.lucene.benchmark.byTask.tasks.ReadTokensTask

- All Implemented Interfaces:
    Cloneable

      public class ReadTokensTask
      extends PerfTask

  Simple task to test performance of tokenizers. It just creates a token stream for each field of the document and read all tokens out of that stream.

  - ### 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`

    - #### getLogMessage

          protected String getLogMessage(int recsCount)

      Overrides:
        `getLogMessage` in class `PerfTask`

    - #### 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`
