Instance Constructors

  1. new H2OFrame()

  2. new H2OFrame(parseSetup: ParseSetup, file: File)

    Create a new frame by parsing given file.

    Create a new frame by parsing given file.

    parseSetup

    setup for parser

    file

    cluster-local file to parse (has to be available on each node)

    returns

    a new frame containing parsed file data

  3. new H2OFrame(file: File)

    Create a new frame by parsing given file.

    Create a new frame by parsing given file.

    file

    cluster-local file to parse (has to be available on each node)

    returns

    a new frame containing parsed file data

  4. new H2OFrame(uris: URI*)

    Create a new frame by parsing given files.

    Create a new frame by parsing given files.

    uris

    URIs of files to parse

    returns

    new H2O frame containing parsed data

  5. new H2OFrame(parseSetup: ParseSetup, uris: URI*)

    Create a new frame by parsing given files.

    Create a new frame by parsing given files.

    parseSetup

    setup for parser

    uris

    URIs of files to parse

    returns

    new H2O frame containing parsed data

  6. new H2OFrame(key: String)

    Create a new H2OFrame based on existing Java Frame referenced by its key.

    Create a new H2OFrame based on existing Java Frame referenced by its key.

    key

    string representation of a reference to Java Frame

    returns

    new H2O frame

  7. new H2OFrame(key: Key[Frame])

    Create a new H2OFrame based on existing Java Frame referenced by its key.

    Create a new H2OFrame based on existing Java Frame referenced by its key.

    key

    reference to Java Frame

    returns

    new H2O frame

  8. new H2OFrame(fr: Frame)

    Create a new H2OFrame based on existing Java Frame.

    Create a new H2OFrame based on existing Java Frame.

    Simple field copy, so the Frames share underlying arrays. Recommended that the input Java Frame be dead after this call.

    fr

    Java frame

    returns

    new H2O frame with parsed data
