public class SplitArrayField extends Transformer
Flattens an array field by creating one record for each value. See FieldPath for supported field name expressions.

  • Constructor Details

    • SplitArrayField

      public SplitArrayField(String name)
      Creates a transformer for the named array field; it only works in a TransformingReader, since the copies are pushed back into that reader.

      public String getName()

    • transform

      public boolean transform(Record record) throws Throwable
      Description copied from class: Transformer
      Applies this transformer to a record on its way through a TransformingReader or TransformingWriter.

      Contract for subclasses (see also docs/authoring/Transformer.md):

      • Mutate record in place as needed.
      • Return true to keep the record in the pipeline.
      • Return false to drop the record (the host routes it to a discard writer if one is configured, otherwise it disappears).
      • Throw to fail (or route to a discard writer, depending on host configuration).
      • Do not call incrementRecordCount() on the host endpoint; the host handles it.
