Constructor Details

SMCollectionMappingImpl

public SMCollectionMappingImpl()

Method Details

getSystemName

public String getSystemName()

Description copied from interface: SimilarityMeasure

The system name can be used to distinguish the similarity measures. Each similarity measure that can be instantiated contains a static final field called NAME representing the system name, e.g., SMAggregateEuclidian.NAME

The system name must also be given during initialization, see SimilarityModel.createSimilarityMeasure(String, DataClass).

Specified by:

getSystemName in interface SimilarityMeasure

Returns:

The system name of the similarity measure. This is equal to SimilarityMeasure.NAME.

isSimilarityFor

public boolean isSimilarityFor(DataClass dataclass,
 String orderName)

Overrides:

isSimilarityFor in class SMCollectionImpl

getMaxQueueSize

public int getMaxQueueSize()

Description copied from interface: SMCollectionMapping

Gets the queue size of the A* measure

Specified by:

getMaxQueueSize in interface SMCollectionMapping

Returns:

The maximum queue size

setMaxQueueSize

public void setMaxQueueSize(int qSize)

Description copied from interface: SMCollectionMapping

Sets the maximum size of the queue that stores the (partial) solutions of the A* algorithm. If the current queue grows larger than the set maximum, the lowest ranked solutions will be removed. Setting a negative value disables pruning of the queue.

Specified by:

setMaxQueueSize in interface SMCollectionMapping

Parameters:

qSize - The maximum queue size

compute

public Similarity compute(DataObject queryObject,
 DataObject caseObject,
 SimilarityValuator valuator)

Specified by:

compute in interface SimilarityMeasure

Returns:

isReusable

public boolean isReusable()

Specified by:

isReusable in interface SimilarityMeasure

Overrides:

isReusable in class SimilarityMeasureImpl

Returns:

true if the measure is reusable

initializeBasedOn

protected void initializeBasedOn(SimilarityMeasure base)

Description copied from class: SimilarityMeasureImpl

Initialize measure based on existing instance

Overrides:

initializeBasedOn in class SMCollectionImpl

Parameters:

base - similarity measure to base on
