Package org.anchoranalysis.feature.session

Class SequentialSession<T extends FeatureInput>

Object

org.anchoranalysis.feature.session.SequentialSession<T>

Type Parameters:

T - input-type for feature

All Implemented Interfaces:

FeatureCalculatorMulti<T>

public class SequentialSession<T extends FeatureInput>
extends Object
implements FeatureCalculatorMulti<T>

Calculates features with successively different inputs, without caching any results from one input to the next.

i.e. caching is applied only within each call to calculate(FeatureInput) not but among successive calls.

All feature use the same initialization, but successively different {#FeatureCalculation} sequentially.

Method Details

start

public void start(FeatureInitialization initialization, SharedFeatures sharedFeatures, org.anchoranalysis.core.log.Logger logger) throws org.anchoranalysis.core.exception.InitializeException

Starts the session.

Parameters:

initialization - the parameters used to initialize the feature.

logger - the logger.

sharedFeatures - features that can be referenced by all the features being calculated in the session. They are also initialized by this session.

Throws:

org.anchoranalysis.core.exception.InitializeException - if any initialization fails to complete successfully.

calculateSuppressErrors

public ResultsVector calculateSuppressErrors(T input, org.anchoranalysis.core.log.error.ErrorReporter errorReporter)

Calculates the results for the next input in the session, reporting any exceptions into an ErrorReporter.

Specified by:

calculateSuppressErrors in interface FeatureCalculatorMulti<T extends FeatureInput>

Parameters:

input - the input to calculate results for.

errorReporter - where to report errors to.

Returns:

the calculated results.
