## Class MockDirectoryWrapper.Failure

- java.lang.Object
- - org.apache.lucene.store.MockDirectoryWrapper.Failure

- Enclosing class:
    MockDirectoryWrapper

      public static class MockDirectoryWrapper.Failure
      extends Object

  Objects that represent fail-able conditions. Objects of a derived class are created and registered with the mock directory. After register, each object will be invoked once for each first write of a file, giving the object a chance to throw an IOException.

    - #### doFail

          protected boolean doFail

  - ### Constructor Detail

    - #### Failure

          public Failure()

  - ### Method Detail

    - #### eval

          public void eval(MockDirectoryWrapper dir)
                    throws IOException

      eval is called on the first write of every new file.
      Throws:
        `IOException`

    - #### reset

          public MockDirectoryWrapper.Failure reset()

      reset should set the state of the failure to its default (freshly constructed) state. Reset is convenient for tests that want to create one failure object and then reuse it in multiple cases. This, combined with the fact that Failure subclasses are often anonymous classes makes reset difficult to do otherwise. A typical example of use is Failure failure = new Failure() { ... }; ... mock.failOn(failure.reset())

    - #### setDoFail

          public void setDoFail()

    - #### clearDoFail

          public void clearDoFail()
