Type Members

1. case class AugmentedTabularMetadata(tabularSchema: TabularSchema, originalMetadata: TabularIOMetadata) extends TabularIOMetadata with Product with Serializable

   

   Used when the original metadata produced by the operator had a partial schema.

   Used when the original metadata produced by the operator had a partial schema. We then check the step run results, if they exist and match the current operator parameters, and pass along that tabularSchema.

   tabularSchema

   TabularSchema from step run results.

   originalMetadata

   Original Metadata, produced by the OperatorGUINode.

2. case class EmptyIOMetadata() extends IOMetadata with Product with Serializable

   

   Used when the operator has no information to pass along.

3. trait OperatorDesignContext extends AnyRef

   

4. class OperatorDesignContextImpl extends OperatorDesignContext

   

   Contains information that the operator may need in OperatorGUINode#getOperatorStatus.

   Contains information that the operator may need in OperatorGUINode#getOperatorStatus. We use a single class for all the arguments to make it easier to add things without breaking compatibility with old operators.

5. trait TabularIOMetadata extends IOMetadata

   

   Used to pass along column and data source information when the data-source is expected to be tabular.

6. case class TabularIOMetadataDefault(tabularSchema: TabularSchema, datasource: DataSource) extends TabularIOMetadata with Product with Serializable

   

   The default class for pass along TabularSchema and data-source information.

   The default class for pass along TabularSchema and data-source information.

   Note that if the TabularSchema used here has the isPartial flag to set to true, then we may wrap this in AugmentedTabularMetadata, if we can get the full TabularSchema from step run results.
