## Interface LearningEnvironment

-     public interface LearningEnvironment

  Specifies a set of utility-objects helpful at runtime but optional for learning algorithm (like thread pool for parallel learning in bagging model or logger).

- - ### Field Detail

    - #### DEFAULT_TRAINER_ENV

          static final LearningEnvironment DEFAULT_TRAINER_ENV

      Default environment

  - ### Method Detail

    - #### parallelismStrategy

          ParallelismStrategy parallelismStrategy()

      Returns Parallelism Strategy instance.

    - #### logger

          MLLogger logger()

      Returns an instance of logger.

    - #### randomNumbersGenerator

          Random randomNumbersGenerator()

      Random numbers generator.
      Returns:
        Random numbers generator.

    - #### logger

          <T> MLLogger logger(Class<T> forCls)

      Returns an instance of logger for specific class.
      Parameters:
        `forCls` - Logging class context.

    - #### partition

          int partition()

      Gets current partition. If this is called not in one of compute tasks of `Dataset`, will return -1.
      Returns:
        Partition.

    - #### dataTtl

          long dataTtl()

      Returns partition data time-to-live in seconds (-1 for an infinite lifetime).

        Partition data time-to-live in seconds (-1 for an infinite lifetime).

    - #### deployingContext

          DeployingContext deployingContext()

      Returns deploy context instance.
      Returns:
        Deploy context.

    - #### initDeployingContext

          default void initDeployingContext(Object clientSideObj)

      Initializes deploying context by object representing current client computation with classes unknown for server side.
      Parameters:
        `clientSideObj` - Client side object.
