## Class BaseRedirectorHelperTask

- java.lang.Object
- - org.apache.tools.ant.ProjectComponent
  - - org.apache.tools.ant.Task
    - - org.apache.catalina.ant.BaseRedirectorHelperTask

- All Implemented Interfaces:
    Cloneable
  Direct Known Subclasses:
    AbstractCatalinaTask, JMXAccessorTask, ValidatorTask

      public abstract class BaseRedirectorHelperTask
      extends org.apache.tools.ant.Task

  Abstract base class to add output redirection support for Catalina Ant tasks. These tasks require Ant 1.5 or later.
  WARNING: due to depends chain, Ant could call a Task more than once and this can affect the output redirection when configured. If you are collecting the output in a property, it will collect the output of only the first run, since Ant properties are immutable and once created they cannot be changed.
  If you are collecting output in a file the file will be overwritten with the output of the last run, unless you set append="true", in which case each run will append it's output to the file.
  Since:
    5.5

- - ### Field Detail

    - #### redirector

          protected org.apache.tools.ant.taskdefs.Redirector redirector

      Redirector helper

    - #### redirectorElement

          protected org.apache.tools.ant.types.RedirectorElement redirectorElement

      Redirector element for this task

    - #### redirectOutStream

          protected OutputStream redirectOutStream

      The stream for info output

    - #### redirectErrStream

          protected OutputStream redirectErrStream

      The stream for error output

    - #### failOnError

          protected boolean failOnError

      Whether to fail (with a BuildException) if ManagerServlet returns an error. The default behavior is to do so. This flag does not control parameters checking. If the task is called with wrong or invalid parameters, it will throw BuildException independently from the setting of this flag.

    - #### redirectOutput

          protected boolean redirectOutput

      `true` true when output redirection is requested for this task. Default is to log on Ant log.

    - #### redirectorConfigured

          protected boolean redirectorConfigured

      will be set to `true` when the configuration of the Redirector is complete.

    - #### alwaysLog

          protected boolean alwaysLog

      Flag which indicates that, if redirected, output should also be always sent to the log. Default is that output is sent only to redirected streams.

  - ### Constructor Detail

    - #### BaseRedirectorHelperTask

          public BaseRedirectorHelperTask()

  - ### Method Detail

    - #### setFailonerror

          public void setFailonerror(boolean fail)

      Whether to fail (with a BuildException) if ManagerServlet returns an error. The default behavior is to do so.
      Parameters:
        `fail` - The new value of failonerror

    - #### isFailOnError

          public boolean isFailOnError()

      Returns the value of the failOnError property.
      Returns:
        `true` if the task should will if an error occurs, otherwise `false`

    - #### setOutput

          public void setOutput(File out)

      File the output of the task is redirected to.

        `error` - name of the error file

    - #### setLogError

          public void setLogError(boolean logError)

      Controls whether error output is logged. This is only useful when output is being redirected and error output is desired in the Ant log
      Parameters:
        `logError` - if true the standard error is sent to the Ant log system and not sent to output stream.

    - #### setOutputproperty

          public void setOutputproperty(String outputProperty)

      Property name whose value should be set to the output of the task.
      Parameters:
        `outputProperty` - property name

    - #### setErrorProperty

          public void setErrorProperty(String errorProperty)

      Property name whose value should be set to the error of the task.

          public void setAppend(boolean append)

      If true, append output to existing file.
      Parameters:
        `append` - if true, append output to existing file

    - #### setAlwaysLog

          public void setAlwaysLog(boolean alwaysLog)

      If true, (error and non-error) output will be redirected as specified while being sent to Ant's logging mechanism as if no redirection had taken place. Defaults to false.
      Actually handled internally, with Ant 1.6.3 it will be handled by the `Redirector` itself.
      Parameters:
        `alwaysLog` - `boolean`

    - #### setCreateEmptyFiles

          public void setCreateEmptyFiles(boolean createEmptyFiles)
