Class EmptyResponseProcessor<T extends Output<T>>

java.lang.Object

org.tribuo.data.columnar.processors.response.EmptyResponseProcessor<T>

All Implemented Interfaces:

com.oracle.labs.mlrg.olcut.config.Configurable, com.oracle.labs.mlrg.olcut.provenance.Provenancable<com.oracle.labs.mlrg.olcut.provenance.ConfiguredObjectProvenance>, ResponseProcessor<T>

public final class EmptyResponseProcessor<T extends Output<T>>
extends Object
implements ResponseProcessor<T>

A ResponseProcessor that always emits an empty optional.

This class is designed to be used when loading columnar datasets which will never have a response (e.g., for clustering or anomaly detection).

It still requires an output factory, even though it's never used to generate an output, because the output factory provides the type for the columnar infrastructure.

Constructor Details

EmptyResponseProcessor

public EmptyResponseProcessor(OutputFactory<T> outputFactory)

Constructs a response processor which never emits a response.

It contains an output factory as this types the whole columnar infrastructure.

Parameters:

outputFactory - The output factory to use.

Method Details

getOutputFactory

public OutputFactory<T> getOutputFactory()

Description copied from interface: ResponseProcessor

Gets the OutputFactory this ResponseProcessor uses.

Specified by:

getOutputFactory in interface ResponseProcessor<T extends Output<T>>

Returns:

The output factory.

getFieldName

@Deprecated
public String getFieldName()

Deprecated.

Specified by:

getFieldName in interface ResponseProcessor<T extends Output<T>>

Returns:

The field name.

setFieldName

@Deprecated
public void setFieldName(String fieldName)

Deprecated.

This is a no-op as the empty response processor doesn't inspect a field.

Specified by:

setFieldName in interface ResponseProcessor<T extends Output<T>>

Parameters:

fieldName - The field name.

process

@Deprecated
public Optional<T> process(String value)

Deprecated.

This method always returns Optional.empty().

Specified by:

process in interface ResponseProcessor<T extends Output<T>>

Parameters:

value - The value to process.

Returns:

Optional.empty().

process

public Optional<T> process(List<String> values)

This method always returns Optional.empty().

Specified by:

process in interface ResponseProcessor<T extends Output<T>>

Parameters:

values - The values to process.

Returns:

Optional.empty().

getFieldNames

public List<String> getFieldNames()

Description copied from interface: ResponseProcessor

Gets the field names this ResponseProcessor uses.

Specified by:

getFieldNames in interface ResponseProcessor<T extends Output<T>>

Returns:

The field names.

toString

public String toString()

Overrides:

toString in class Object

getProvenance

public com.oracle.labs.mlrg.olcut.provenance.ConfiguredObjectProvenance getProvenance()

Specified by:

getProvenance in interface com.oracle.labs.mlrg.olcut.provenance.Provenancable<T extends Output<T>>
