## Interface JavaCompiler.CompilationTask

- All Superinterfaces:
    Callable<Boolean>
  Enclosing interface:
    JavaCompiler

      public static interface JavaCompiler.CompilationTask
      extends Callable<Boolean>

  Interface representing a future for a compilation task. The compilation task has not yet started. To start the task, call the call method.

  Before calling the call method, additional aspects of the task can be configured, for example, by calling the setProcessors method.

- - ### Method Summary

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `Boolean` | `call()` Performs this compilation task.
    `void` | `setLocale(Locale locale)` Set the locale to be applied when formatting diagnostics and other localized data.
    `void` | `setProcessors(Iterable<? extends Processor> processors)` Sets processors (for annotation processing).

- - ### Method Detail

    - #### setProcessors

          void setProcessors(Iterable<? extends Processor> processors)

      Sets processors (for annotation processing). This will bypass the normal discovery mechanism.
      Parameters:
        `processors` - processors (for annotation processing)
      Throws:
        `IllegalStateException` - if the task has started

    - #### setLocale

          void setLocale(Locale locale)

      Set the locale to be applied when formatting diagnostics and other localized data.
      Parameters:
        `locale` - the locale to apply; `null` means apply no locale
      Throws:
        `IllegalStateException` - if the task has started

    - #### call

          Boolean call()

      Performs this compilation task. The compilation may only be performed once. Subsequent calls to this method throw IllegalStateException.
      Specified by:
        `call` in interface `Callable<Boolean>`
      Returns:
        true if and only all the files compiled without errors; false otherwise
      Throws:
        `RuntimeException` - if an unrecoverable error occurred in a user-supplied component. The cause will be the error in user code.
        `IllegalStateException` - if called more than once
