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 Detail

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 Detail

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

public String getFieldName()

Description copied from interface: ResponseProcessor

Gets the field name this ResponseProcessor uses.

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

public Optional<T> process(String value)

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().

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<com.oracle.labs.mlrg.olcut.provenance.ConfiguredObjectProvenance>
