trait SimpleFeatureArrowFileReader extends Closeable

For reading simple features from an arrow file written by SimpleFeatureArrowFileWriter.

Expects arrow streaming format (no footer). Can handle multiple 'files' in a single input stream

    Annotations
    @throws( classOf[java.io.IOException] )
  2. abstract def dictionaries: Map[String, ArrowDictionary]

    Dictionaries from the file.

    Dictionaries from the file. Note: this may change as features are read, if there are multiple logical 'files' in the input stream. This method is exposed for completeness, but generally would not be needed since dictionary values are automatically decoded into the returned simple features.

    returns

    current dictionaries, keyed by attribute

  3. abstract def features(filter: Filter = Filter.INCLUDE): CloseableIterator[ArrowSimpleFeature]

    Reads features from the underlying arrow file

    Reads features from the underlying arrow file

    filter

    filter to apply

  4. abstract def sft: SimpleFeatureType

    The simple feature type for the file.

    The simple feature type for the file. Note: this may change as features are read, if there are multiple logical 'files' in the input stream. By convention, we keep a single file with a single sft, but that is not enforced.

    returns

    current simple feature type
