Constructor Details

SingleRowPerInput

protected SingleRowPerInput(String headerIdentifier)

Creates with a single non-group header that should be describe an identifier.

Parameters:

headerIdentifier - the column-name to describe an identifier.

SingleRowPerInput

public SingleRowPerInput(String[] nonGroupHeaders)

Creates a new SingleRowPerInput instance.

Parameters:

nonGroupHeaders - The column names (not pertaining to groups), the first of which should refer to an identifier.

Method Details

createExporter

public FeatureExporter<FeatureList<S>> createExporter(LabelHeaders metadataHeaders,
 List<NamedBean<FeatureListProvider<S>>> features,
 FeatureOutputNames outputNames,
 Optional<InputGrouper> grouper,
 FeatureExporterContext context)
                                               throws CreateException

Description copied from class: FeatureSource

Creates the FeatureExporter to be used for calculating and exporting feature-results.

Specified by:

createExporter in class FeatureSource<T extends InputFromManager, FeatureList<S extends FeatureInput>, S extends FeatureInput>

Parameters:

metadataHeaders - headers to use for additional "metadata" before feature-results.

features - the features to calculate.

outputNames - the names of various kind of outputs.

grouper - when defined, assigns each input to a group.

context - IO-context.

Returns:

a newly created FeatureExporter as matches this source of features.

Throws:

CreateException - if it cannot be created.

headers

public LabelHeaders headers(boolean groupsEnabled)

Description copied from class: FeatureSource

Generates label-headers for the non-feature-result columns in the CSV.

Specified by:

headers in class FeatureSource<T extends InputFromManager, FeatureList<S extends FeatureInput>, S extends FeatureInput>

Parameters:

groupsEnabled - whether groups are enabled

Returns:

a LabelHeaders object for the non-feature-result columns

calculateAndOutput

public void calculateAndOutput(T input,
 FeatureCalculationContext<FeatureList<S>> context)
                        throws OperationFailedException

Description copied from class: FeatureSource

Processes one input to calculate feature-results and output them to the file-system.

Specified by:

calculateAndOutput in class FeatureSource<T extends InputFromManager, FeatureList<S extends FeatureInput>, S extends FeatureInput>

Parameters:

input - one particular input that will create one or more "rows" in a feature-table

context - the FeatureCalculationContext for calculation

Throws:

OperationFailedException - if the operation fails

calculateResultsForInput

protected abstract ResultsVectorWithThumbnail calculateResultsForInput(T input,
 FeatureCalculationContext<FeatureList<S>> context)
                                                                throws NamedFeatureCalculateException

Calculates feature-results for a particular input.

Parameters:

input - the input.

context - context for calculating features.

Returns:

the results, with optionally associated thumbnail.

Throws:

NamedFeatureCalculateException - if any feature cannot calculate.

additionalLabelsFor

protected abstract Optional<String[]> additionalLabelsFor(T input)
                                                   throws OperationFailedException

Additional labels for an input to include (after the identifier, and before any group labels).

These should always correspond (when appended to the identifier) exactly to the nonGroupHeaders.

Parameters:

input - the input.

Returns:

any additional labels for the input.

Throws:

OperationFailedException - if the operation fails
