Method Details

compute

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

Specified by:

compute in interface SimilarityMeasure

Returns:

getOrderName

public String getOrderName()

Specified by:

getOrderName in interface SMInterval

setOrderName

public void setOrderName(String orderName)
                  throws ProCAKENameNotFoundException

Specified by:

setOrderName in interface SMInterval

Throws:

ProCAKENameNotFoundException

getSimilarityToUse

public String getSimilarityToUse()

Specified by:

getSimilarityToUse in interface SMInterval

Returns:

The defined name of the SimilarityMeasure that should be used for the elements.

See Also:

• SMInterval.setSimilarityToUse(String)

setSimilarityToUse

public void setSimilarityToUse(String similarityToUse)

Description copied from interface: SMInterval

In general, the element objects of the interval are compared with their default similarity measure. But in some situations it can be necessary to use another similarity measure for the elements of an interval. Therefore, it exists the possibility to specify a similarity measure name that should be used instead. For each DataObject a similarity measure with that name should exist. Otherwise, the comparision of objects are ignored.

Summarizing:

• If the newValue is null the default measures of the objects are used. This is the default behaviour.
• If the newValue is the name of a similarity measure, for each data class whose objects can be occured in the interval a similarity measure with this name must exist.

Specified by:

setSimilarityToUse in interface SMInterval

Parameters:

similarityToUse - The name of the similarity measure that should be used for the elements.

getStrategy

public Strategy getStrategy()

Specified by:

getStrategy in interface SMInterval

setStrategy

public void setStrategy(Strategy strategy)

Specified by:

setStrategy in interface SMInterval

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.

initialize

protected void initialize()

Description copied from class: SimilarityMeasureImpl

This method will be called after the DataClass is set by cake.data.similarity.SimilarityMeasureImpl#compute(cake.data.objects.DataObject, de.uni_trier.wi2.procake.data.objects.DataObject) . Override this method to initialize your SimilarityMeasure.

Overrides:

initialize in class SimilarityMeasureImpl

See Also:

• SimilarityMeasure.compute(DataObject, DataObject, SimilarityValuator)

isInterval

public boolean isInterval()

Overrides:

isInterval in class SimilarityMeasureImpl

isSimilarityFor

public boolean isSimilarityFor(DataClass dataclass,
 String orderName)

Specified by:

isSimilarityFor in class SimilarityMeasureImpl

removeOrder

public void removeOrder()

Description copied from interface: SMInterval

Similarity measure for intervals can work also on the natural order of a AtomicDataClass if available. Therefore, it is possible to remove an already assigned order.

Specified by:

removeOrder in interface SMInterval
