Types

class CellConversionException(value: Any?, from: KType, to: KType, column: ColumnPath, val row: Int?, val cause: Throwable?) : TypeConversionException

ColumnNotFoundException

class ColumnNotFoundException(val columnName: String, val message: String) : RuntimeException, DataFrameError

ColumnsWithDifferentParentException

class ColumnsWithDifferentParentException(message: String) : IllegalArgumentException, DataFrameError

ColumnTypeMismatchesColumnValuesException

class ColumnTypeMismatchesColumnValuesException(val column: DataColumn<*>, cause: Throwable) : RuntimeException

Extension properties are generated according to DataColumn.type property DataColumn.type must match types of DataColumn.values, but it can fail to do so. This causes ClassCastException or NullPointerException when you use extension property and actual value is of different type or is null. If generated extension property causes this exception, this is a bug in the library You can work around this problem by referring to column using String API

DuplicateColumnNamesException

class DuplicateColumnNamesException(val allColumnNames: List<String>) : IllegalArgumentException, DataFrameError

ExcessiveColumnsException

UnequalColumnSizesException

class UnequalColumnSizesException(val expectedRowsCount: Int, val columnSizes: List<Pair<String, Int>>) : IllegalArgumentException
