Constructor Details

SMTaxonomyClassicUserWeightsImpl

public SMTaxonomyClassicUserWeightsImpl()

Method Details

getDefinedNodes

public List<AtomicObject> getDefinedNodes()

Specified by:

getDefinedNodes in interface SMTaxonomyClassicUserWeights

Returns:

A list of defined AtomicObjects

See Also:

• AtomicObject

getNodeWeight

public Double getNodeWeight(AtomicObject nodeValue)

Overrides:

getNodeWeight in class SMTaxonomyWeightedNodes

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

Overrides:

getSystemName in class SMTaxonomyClassicImpl

Returns:

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

getWeight

public Double getWeight(AtomicObject nodeValue)

Specified by:

getWeight in interface SMTaxonomyClassicUserWeights

Parameters:

nodeValue - The value of the node.

Returns:

The weight of the given node. If no weight is defined, null will be returned.

removeWeight

public void removeWeight(AtomicObject nodeValue)

Description copied from interface: SMTaxonomyClassicUserWeights

Removes the value of the node. If no value exists, noting happens.

Specified by:

removeWeight in interface SMTaxonomyClassicUserWeights

Parameters:

nodeValue - A nodes is specified by its value.

removeAllWeights

public void removeAllWeights()

Description copied from interface: SMTaxonomyClassicUserWeights

Removes all weights.

Specified by:

removeAllWeights in interface SMTaxonomyClassicUserWeights

setWeight

public void setWeight(AtomicObject nodeValue,
 Double weight)

Specified by:

setWeight in interface SMTaxonomyClassicUserWeights

weight - must be between 0 and 1

initClassCaches

public void initClassCaches()

Overrides:

initClassCaches in class SMTaxonomyClassicImpl

checkForDuplicateNodeNames

public void checkForDuplicateNodeNames()

This method checks if the taxonomy contains duplicate node entries. A duplicate in the taxonomy-structure is not allowed. A duplicate in the value-enumeration is eliminated because this value enumeration is internally stored as a set.

checkForDescendingWeightsTowardsRoot

public void checkForDescendingWeightsTowardsRoot()

This method checks if the weights of all nodes are descending towards the root. This is required by the definition of the taxonomy.

checkForMissingWeights

public void checkForMissingWeights()

This method checks if all defined inner nodes have an associated weight. Whereas the node itself is defined in the model, the similarity weight is defined in the similarity model.
