Public NotInheritable Class StatefulCustomMappingTransformer(Of TSrc, TDst, TState)
Implements ITransformer

Type Parameters

TSrc

The class defining which columns to take from the incoming data.

TDst

The class defining which new columns are added to the data.

TState

The type that describes per-cursor state.

Inheritance: Object
StatefulCustomMappingTransformer<TSrc,TDst,TState>

Implements: ICanSaveModel ITransformer

Methods

GetOutputSchema(DataViewSchema)	Returns the DataViewSchema which would be produced by the transformer applied to an input data with schema `inputSchema`.
Transform(IDataView)	Take the data in, make transformations, output the data. Note that IDataView's are lazy, so no actual transformations happen here, just schema validation.

Explicit Interface Implementations

ICanSaveModel.Save(ModelSaveContext)
ITransformer.GetRowToRowMapper(DataViewSchema)	Constructs a row-to-row mapper based on an input schema. If IsRowToRowMapper is `false`, then an exception is thrown. If the `inputSchema` is in any way unsuitable for constructing the mapper, an exception is likewise thrown.
ITransformer.IsRowToRowMapper	Whether a call to GetRowToRowMapper(DataViewSchema) should succeed, on an appropriate schema.

Extension Methods

Preview(ITransformer, IDataView, Int32)	Preview an effect of the `transformer` on a given `data`.
Append<TTrans>(ITransformer, TTrans)	Create a new transformer chain, by appending another transformer to the end of this transformer chain.
CreateTimeSeriesEngine<TSrc,TDst>(ITransformer, IHostEnvironment, PredictionEngineOptions)	TimeSeriesPredictionEngine<TSrc,TDst> creates a prediction engine for a time series pipeline. It updates the state of time series model with observations seen at prediction phase and allows checkpointing the model.
CreateTimeSeriesEngine<TSrc,TDst>(ITransformer, IHostEnvironment, Boolean, SchemaDefinition, SchemaDefinition)	TimeSeriesPredictionEngine<TSrc,TDst> creates a prediction engine for a time series pipeline. It updates the state of time series model with observations seen at prediction phase and allows checkpointing the model.
