Abstract Value Members

  1. abstract def addendum: Map[String, AnyRef]

    Used to store additional information, for example information needed for visualization.

    Used to store additional information, for example information needed for visualization.

    For serialization purposes, the values in the map must be simple objects - Numbers, Strings, Lists, with no custom classes.

    returns

    Map containing additional information.

  2. abstract def displayName: String

    This is used to display a customized name of the output from the UI.

    This is used to display a customized name of the output from the UI.

    returns

    The display name for this object.

    IOBase

  3. abstract def path: String

    Path specifying the location of the file in HDFS.

    Path specifying the location of the file in HDFS.

    returns

    Path of the file in HDFS.

    HdfsFile

  4. abstract def sourceOperatorInfo: Option[OperatorInfo]

    An IOBase object is always output by an operator.

    An IOBase object is always output by an operator. Off-shelf IOBase implementations use this function to return the identifying information of the most recent operator that returned this object. Note that if the user has changed the name of the operator since this IOBase object was created, the source operator name here will be the previous name, not the current one.

    Will be None if this is a Tuple or List representing IOBase objects from several operators, or for IONone.

    The UUID is unique to each operator within a workflow, and does not change for the lifetime of the operator.

    returns

    The name of the source operator that returned this.
