      • makeCollation

        public java.util.Comparator makeCollation​(Configuration config,
                                          java.util.Properties props)
                                   throws XPathException
        Obtain a collation with a given set of properties. The set of properties is extensible and variable across platforms. Common properties with example values include lang=ed-GB, strength=primary, case-order=upper-first, ignore-modifiers=yes, alphanumeric=yes. Properties that are not supported are generally ignored; however some errors, such as failing to load a requested class, are fatal.
        Specified by:
        makeCollation in interface Platform
        Parameters:
        config - the configuration object
        props - the desired properties of the collation
        Returns:
        a collation with these properties
        Throws:
        XPathException - if a fatal error occurs

      • canReturnCollationKeys

        public boolean canReturnCollationKeys​(java.util.Comparator collation)
        Given a collation, determine whether it is capable of returning collation keys. The essential property of collation keys is that if two values are equal under the collation, then the collation keys are equal under the equals() method.
        Specified by:
        canReturnCollationKeys in interface Platform
        Parameters:
        collation - the collation, provided as a Comparator
        Returns:
        true if this collation can supply collation keys

      • getCollationKey

        public java.lang.Object getCollationKey​(java.util.Comparator collation,
                                        java.lang.String value)
        Given a collation, get a collation key. The essential property of collation keys is that if two values are equal under the collation, then the collation keys are compare correctly under the compareTo method.
        Specified by:
        getCollationKey in interface Platform
        Returns:
        a representation of the collation key, such that two collation keys are equal() if and only if the string values they represent are equal under the specified collation.
        Throws:
        java.lang.ClassCastException - if the collation is not one that is capable of supplying collation keys (this should have been checked in advance)
