Methods

CustomMapping<TSrc,TDst>(TransformsCatalog, Action<TSrc,TDst>, String, SchemaDefinition, SchemaDefinition)	Create a CustomMappingEstimator<TSrc,TDst>, which applies a custom mapping of input columns to output columns.
FilterByCustomPredicate<TSrc>(DataOperationsCatalog, IDataView, Func<TSrc,Boolean>)	Drop rows where a specified predicate returns true.
FilterByStatefulCustomPredicate<TSrc,TState>(DataOperationsCatalog, IDataView, Func<TSrc,TState,Boolean>, Action<TState>)	Drop rows where a specified predicate returns true. This filter allows to maintain a per-cursor state.
StatefulCustomMapping<TSrc,TDst,TState>(TransformsCatalog, Action<TSrc,TDst,TState>, Action<TState>, String)	Create a StatefulCustomMappingEstimator<TSrc,TDst,TState>, which applies a custom mapping of input columns to output columns, while allowing a per-cursor state.
