NullabilityOptions
Indicates how DataColumn.hasNulls (or, more accurately, DataColumn.type.isMarkedNullable) should be initialized from expected schema and actual data when reading schema-defined data formats.
Entries
Use only actual data, set DataColumn.hasNulls to true if and only if there are null values in the column. On an empty dataset, use false.
Set DataColumn.hasNulls to the expected value. Throws an exception if the column should be not nullable but there are null values.
Set DataColumn.hasNulls to the expected value by default. Change false to true if the column should be not nullable but there are null values.
