    - #### testEnded

          public void testEnded()

      Description copied from interface: `TestStateListener`

      Called once for all threads after the end of a test. This will use the same element instances as at the start of the test.

      N.B. testStarted() and testEnded() are called from different threads.

      Specified by:
        `testEnded` in interface `TestStateListener`
      See Also:
        `StandardJMeterEngine.stopTest()`

    - #### testEnded

          public void testEnded(String host)

      Description copied from interface: `TestStateListener`

      Called once for all threads after the end of a test. This will use the same element instances as at the start of the test.

      N.B. testStarted() and testEnded() are called from different threads.

      Specified by:
        `testStarted` in interface `TestStateListener`
      See Also:
        `StandardJMeterEngine.run()`

    - #### testStarted

          public void testStarted(String host)

      Description copied from interface: `TestStateListener`

      Called just before the start of the test from the main engine thread. This is before the test elements are cloned. Note that not all the test variables will have been set up at this point.

      N.B. testStarted() and testEnded() are called from different threads.

      Specified by:
        `testStarted` in interface `TestStateListener`
      Parameters:
        `host` - name of host
      See Also:
        `StandardJMeterEngine.run()`

    - #### clone

          public Object clone()

      Specified by:

    - #### getConnectionInfo

          public static String getConnectionInfo(String poolName)
                                          throws SQLException

      Gets a textual description about the pools configuration.
      Parameters:
        `poolName` - Pool name
      Returns:
        Connection information on `poolName` or a short message, when the JMeter object specified by `poolName` is not a pool
      Throws:
        `SQLException` - when an error occurs, while gathering information about the connection

    - #### getConnection

          public static Connection getConnection(String poolName)
                                          throws SQLException

      Utility routine to get the connection from the pool.
      Purpose:
      - allows JDBCSampler to be entirely independent of the pooling classes
      - allows the pool storage mechanism to be changed if necessary
      Parameters:
        `poolName` - name of the pool to get a connection from
      Returns:
        a possible cached connection from the pool
      Throws:
        `SQLException` - when an error occurs while getting the connection from the pool

    - #### addConfigElement

          public void addConfigElement(ConfigElement config)

      Description copied from interface: `ConfigElement`
      Add a configuration element to this one. This allows config elements to combine and give a "layered" effect. For example, HTTPConfigElements have properties for domain, path, method, and parameters. If element A has everything filled in, but null for domain, and element B is added, which has only domain filled in, then after adding B to A, A will have the domain from B. If A already had a domain, then the correct behavior is for A to ignore the addition of element B.
      Specified by:
        `addConfigElement` in interface `ConfigElement`
      Parameters:
        `config` - the element to be added to this ConfigElement

    - #### expectsModification

          public boolean expectsModification()

      Description copied from interface: `ConfigElement`
      If your config element expects to be modified in the process of a test run, and you want those modifications to carry over from sample to sample (as in a cookie manager - you want to save all cookies that get set throughout the test), then return true for this method. Your config element will not be cloned for each sample. If your config elements are more static in nature, return false. If in doubt, return false.
      Specified by:
        `expectsModification` in interface `ConfigElement`
      Returns:
        true if the element expects to be modified over the course of a test run
