Abstract Value Members

  1. abstract def addBatchToConcat(batch: ColumnarBatch): Unit

    Called to add a new batch to the final output batch.

    Called to add a new batch to the final output batch. The batch passed in will not be closed. If it needs to be closed it is the responsibility of the child class to do it.

    batch

    the batch to add in.

  2. abstract def cleanupConcatIsDone(): Unit

    Called to cleanup any state when a batch is done (even if there was a failure)

  3. abstract def clearOnDeck(): Unit

    If there is anything saved on deck close it.

    If there is anything saved on deck close it.

  4. abstract def concatAllAndPutOnGPU(): ColumnarBatch

    Called after all of the batches have been added in.

    Called after all of the batches have been added in.

    returns

    the concated batches on the GPU.

  5. abstract def hasOnDeck: Boolean

    Return true if there is something saved on deck for later processing.

    Attributes
    protected
  6. abstract def initNewBatch(batch: ColumnarBatch): Unit

    Called first to initialize any state needed for a new batch to be created.

  7. abstract def popOnDeck(): ColumnarBatch

    Remove whatever is on deck and return it.
