    • Method Detail

      • overwriteMatchingDataClasses

        void overwriteMatchingDataClasses​(Model other)
        Checks for each measure if it contains a DataClass reference that is present in the given 'other' Model. If so, it replaces that reference.
        Parameters:
        other - The Model whose dataclasses should be referenced

      • createSimilarityMeasure

        SimilarityMeasure createSimilarityMeasure​(String name,
                                          DataClass dataClass)
        Creates a new SimilarityMeasure  that is not automatically registered. The registration must be done with the addSimilarityMeasure(SimilarityMeasure, String) method.
        Parameters:
        name - Each similarity measure contains a static field "NAME" that contains the name of the similarity measure, e.g., SMAggregateAverage.NAME. If this field does not exists, the similarity measure can not be instantiated.
        dataClass - The DataClass for that the similarity measure should be created.
        Returns:
        The new SimilarityMeasure  or null if the name does not relate to a similarity measure or the similarity measure does not fit to the data class

      • createAndRegisterSimilarityMeasure

        SimilarityMeasure createAndRegisterSimilarityMeasure​(String uniqueName,

                                                     DataClass dataClass)
                                              throws NameAlreadyExistsException
        Creates a new SimilarityMeasure  and registers
        Parameters:
        uniqueName - a new unique name to identify the new measure
        measureTemplateName - Each similarity measure contains a static field "NAME" that contains the name of the similarity measure, e.g., SMAggregateAverage.NAME. If this field does not exists, the similarity measure can not be instantiated.
        dataClass - The DataClass for that the similarity measure should be created.
        Returns:
        The new SimilarityMeasure  or null if the name does not relate to a similarity * measure or the similarity measure does not fit to the data class
        Throws:
        NameAlreadyExistsException - is thrown if the given name is already defined for the data class.

      • getSimilarityMeasure

        SimilarityMeasure getSimilarityMeasure​(DataClass dataClass)
        Returns a suitable similarity measure for the given data class. Default measures are preferred over other suitable measures.
