      • compare

        public int compare​(java.lang.Object a,
                   java.lang.Object b)
        Compare two string objects.
        Specified by:
        compare in interface java.util.Comparator
        Returns:
        <0 if a0 if a>b
        Throws:
        java.lang.ClassCastException - if the objects are of the wrong type for this Comparer

      • compareCS

        public int compareCS​(java.lang.CharSequence a,
                     java.lang.CharSequence b)
        Compare two CharSequence objects. This is hand-coded to avoid converting the objects into Strings.
        Returns:
        <0 if a0 if a>b
        Throws:
        java.lang.ClassCastException - if the objects are of the wrong type for this Comparer

      • comparesEqual

        public boolean comparesEqual​(java.lang.String s1,
                             java.lang.String s2)
        Test whether one string is equal to another, according to the rules of the XPath compare() function. The result is true if and only if the compare() method returns zero: but the implementation may be more efficient than calling compare and testing the result for zero
        Specified by:
        comparesEqual in interface SubstringMatcher
        Parameters:
        s1 - the first string
        s2 - the second string
        Returns:
        true iff s1 equals s2

      • contains

        public boolean contains​(java.lang.String s1,
                        java.lang.String s2)
        Test whether one string contains another, according to the rules of the XPath contains() function
        Specified by:
        contains in interface SubstringMatcher
        Parameters:
        s1 - the containing string
        s2 - the contained string
        Returns:
        true iff s1 contains s2

      • endsWith

        public boolean endsWith​(java.lang.String s1,
                        java.lang.String s2)
        Test whether one string ends with another, according to the rules of the XPath ends-with() function
        Specified by:
        endsWith in interface SubstringMatcher
        Parameters:
        s1 - the containing string
        s2 - the contained string
        Returns:
        true iff s1 ends with s2

      • startsWith

        public boolean startsWith​(java.lang.String s1,
                          java.lang.String s2)
        Test whether one string starts with another, according to the rules of the XPath starts-with() function
        Specified by:
        startsWith in interface SubstringMatcher
        Parameters:
        s1 - the containing string
        s2 - the contained string
        Returns:
        true iff s1 starts with s2
