Implemented types

Methods

Name Description
Clear()
RemoveAt(Int32) Removes the import definition at the specified index.
UseColumn(Int32, VariableType, String, String) Add a column to be imported from the specified data source column index and configured as the specified variable type. The order in which columns are added determines their order in the table/>. If is `null`, the default unit (in the active unit system) for the specified variable type will be assumed during import. If is `null` or empty, a unique name will be generated from the specified variableType during import. A reference to the instance is returned so that invocations can be chained together.
