        public LinkSpecGeneticLearnerConfig​(KBInfo KBIsource,
                                    KBInfo KBItarget,

                             throws org.jgap.InvalidConfigurationException
        Constructor.
        Parameters:
        KBIsource - Specifies the source knowledge base.
        KBItarget - Specifies the target knowledge base.
        propMapping - A Mapping of Properties of both source and target.
        Throws:
        org.jgap.InvalidConfigurationException - when an invalid value has been passed to a Configuration object

      • getPropertyName

        public String getPropertyName​(String discriminant,
                              int id)
        Little helper function to retrieve plane property names.
        Parameters:
        id - Number of the property in the property List.
        discriminant - String to differ between the two Linked Data Sources dubbed "source" and "target".
        Returns:
        name of the property with the given number.

      • getExpressionProperty

        public String getExpressionProperty​(String discriminant,
                                    int id)
        Function to retrieve properties of the Linked Data sources dubbed source and target completed with the specified variable of the knowledge base to comply with the limes dtd. Variables have in most cases the form "?x", properties are the names of the property possibly starting with a namespace, e.g. "dc:title". But for a metric expression we have to combine both without the question mark: E.g. "x.dc:title".
        Parameters:
        discriminant - String "source" or "target" to differ between the both knowledge bases.
        id - Number of the property in the properties list in the according KBInfo.
        Returns:
        Combined String of variable and property.

      • getExpressionProperty

        public String getExpressionProperty​(String discriminant,
                                    String propName)

      • hasNumericProperties

        public boolean hasNumericProperties()
        Do we have to consider numeric properties?
        Returns:
        True if the given PropertyMapping consists of a mapping of two numeric properties.

      • hasDateProperties

        public boolean hasDateProperties()
        Do we have to consider date properties?
        Returns:
        true iff the given PropertyMapping states a mapping between two date propeties.

      • hasPointSetProperties

        public boolean hasPointSetProperties()
        Do we have to consider pointset properties?
        Returns:
        true iff the given PropertyMapping states a mapping between two date propeties.

        protected boolean redundantCommands()
        In case we don't want to.
        Returns:
