public SMAggregateImpl()

Method Details

getSimilaritiesToUse

public HashMap getSimilaritiesToUse()

Specified by:

getSimilaritiesToUse in interface SMAggregate

Returns:

The defined names of the SimilarityMeasures that should be used for the elements.

See Also:

• SMAggregate.setSimilarityToUse(String, String)

getSimilarityToUse

public String getSimilarityToUse(String attributeName)

Specified by:

getSimilarityToUse in interface SMAggregate

Parameters:

attributeName - The name of the attribute for which the specific similarity should be returned.

Returns:

The name of the similarity measure, that should be used for this attribute. Can be null.

isSimilarityFor

public boolean isSimilarityFor(DataClass dataclass,
 String orderName)

Specified by:

isSimilarityFor in class SimilarityMeasureImpl

setSimilarityToUse

public void setSimilarityToUse(String attributeName,
 String similarityToUse)

Description copied from interface: SMAggregate

In general, the element objects of the collection are compared with their default similarity measure. But in some situations it can be necessary to use another similarity measure for the elements of a collection. 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 collection a similarity measure with this name must exist. Attention, this also include the common super classes of the objects.

Specified by:

setSimilarityToUse in interface SMAggregate

Parameters:

attributeName - The name of the element object.

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

getSimilaritiesToUse

public String getSimilaritiesToUse(String attributeName)

Specified by:

getSimilaritiesToUse in interface SMAggregate

Parameters:

attributeName - The name of the element object.

Returns:

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

computeAttributeSimilarity

protected SimilarityImpl computeAttributeSimilarity(SimilarityValuator valuator,
 DataObject queryObject,
 DataObject caseObject,
 String attName)

isIgnoreNullAttributesInQuery

public boolean isIgnoreNullAttributesInQuery()

Specified by:

isIgnoreNullAttributesInQuery in interface SMAggregate

Returns:

setIgnoreNullAttributesInQuery

public void setIgnoreNullAttributesInQuery(boolean ignoreNullAttributesInQuery)

Specified by:

setIgnoreNullAttributesInQuery in interface SMAggregate

initializeBasedOn

protected void initializeBasedOn(SimilarityMeasure base)

Description copied from class: SimilarityMeasureImpl

Initialize measure based on existing instance

Overrides:

initializeBasedOn in class SimilarityMeasureImpl

Parameters:

base - similarity measure to base on
