Method Details

addSimilarity

public void addSimilarity(DataClass queryDataClass,
 DataClass caseDataClass,
 double similarity)

Description copied from interface: SMTableDataClass

Adds a similarity value for the given data classes.

Specified by:

addSimilarity in interface SMTableDataClass

Parameters:

queryDataClass - The data class for the query.

caseDataClass - The data class for the case.

similarity - The similarity value.

compute

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

Specified by:

compute in interface SimilarityMeasure

Returns:

getCaseDataClasses

public DataClass[] getCaseDataClasses(DataClass forQuery)

Specified by:

getCaseDataClasses in interface SMTableDataClass

Returns:

All case data classes for that and the given query data class name a similarity value is defined.

getDefaultSim

public double getDefaultSim()

Specified by:

getDefaultSim in interface SMTableDataClass

Returns:

The default similarity value.

setDefaultSim

public void setDefaultSim(double defaultSim)

Description copied from interface: SMTableDataClass

Sets the default similarity value that is used if no similarity value for the given query and case is defined.

Specified by:

setDefaultSim in interface SMTableDataClass

getQueryDataClasses

public DataClass[] getQueryDataClasses()

Specified by:

getQueryDataClasses in interface SMTableDataClass

Returns:

All query data class names for that a similarity value is defined.

getSimilarity

public Similarity getSimilarity(DataClass queryDataClass,
 DataClass caseDataClass)

Specified by:

getSimilarity in interface SMTableDataClass

Returns:

The defined similarity value for the query and case data class. If no mapping for this classes is defined the null value will be returned and NOT the default similarity value.

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)

Specified by:

isSimilarityFor in class SimilarityMeasureImpl

isSymmetric

public boolean isSymmetric()

Specified by:

isSymmetric in interface SMTableDataClass

Returns:

true if the similarity definitions are symmetric.

setSymmetric

public void setSymmetric(boolean symmetric)

Specified by:

setSymmetric in interface SMTableDataClass

removeSimilarity

public void removeSimilarity(DataClass queryDataClass,
 DataClass caseDataClass)

Description copied from interface: SMTableDataClass

Removes the similarity value for the given query and case class name. If no similarity value is defined nothing will be removed.

Specified by:

removeSimilarity in interface SMTableDataClass

Parameters:

queryDataClass - the query class to be removed

caseDataClass - the case class to be removed
