createParserUIInitializationData in interface ImportingParser

Overrides:

createParserUIInitializationData in class TreeImportingParserBase

Returns:

ObjectNode options

 ProjectMetadata metadata,
 ImportingJob job,
 String fileSource,
 InputStream is,
 ImportColumnGroup rootColumnGroup,
 int limit,
 com.fasterxml.jackson.databind.node.ObjectNode options,
 List<Exception> exceptions)

Description copied from class: TreeImportingParserBase

Parse a single file from an InputStream. The default implementation just throws a NotImplementedException. Override in subclasses to implement.
