    Annotations
    @throws( classOf[java.io.IOException] )
  2. abstract def get(): T

    Return the current record.

    Return the current record. This method should return same value until next is called.

    Definition Classes
    PartitionReader
  3. abstract def getOffset(): PartitionOffset

    Get the offset of the current record, or the start offset if no records have been read.

    Get the offset of the current record, or the start offset if no records have been read.

    The execution engine will call this method along with get() to keep track of the current offset. When an epoch ends, the offset of the previous record in each partition will be saved as a restart checkpoint.

  4. abstract def next(): Boolean

    Proceed to next record, returns false if there is no more records.

    Proceed to next record, returns false if there is no more records.

    Definition Classes
    PartitionReader
    Exceptions thrown

    IOException if failure happens during disk/network IO like reading files.
