    • Method Detail

      • setType

        public void setType​(Type type)
        Description copied from interface: FSIndexComparator
        Set the type of this comparator. Note that you can use this method more than once, in case you need to generate indexes that are identical except for the type.
        Specified by:
        setType in interface FSIndexComparator
        Parameters:
        type - The type of the index.
      • addKey

        public int addKey​(Feature feat,
                          int compareKey)
        Description copied from interface: FSIndexComparator
        Add a new key.
        Specified by:
        addKey in interface FSIndexComparator
        Parameters:
        feat - The key feature.
        compareKey - The way to compare the key values.
        Returns:
        The number of the key.
      • getKeyFeature

        public Feature getKeyFeature​(int key)
        Description copied from interface: FSIndexComparator
        Get the feature for this key.
        Specified by:
        getKeyFeature in interface FSIndexComparator
        Parameters:
        key - The number of the key.
        Returns:
        The corresponding feature, if it exists; null, else.
      • getKeyComparator

        public int getKeyComparator​(int key)
        Description copied from interface: FSIndexComparator
        Get the comparator for this key.
        Specified by:
        getKeyComparator in interface FSIndexComparator
        Parameters:
        key - The number of the key.
        Returns:
        The corresponding comparator, if it exists; -1, else.
      • equals

        public boolean equals​(java.lang.Object o)
        Description copied from interface: FSIndexComparator
        Test for equality against another FSIndexComparator true iff the comparators have the same keys and comparators.
        Specified by:
        equals in interface FSIndexComparator
        Overrides:
        equals in class java.lang.Object
      • hashCode

        public int hashCode()
        Overrides:
        hashCode in class java.lang.Object
      • isValid

        public boolean isValid()
        Description copied from interface: FSIndexComparator
        Validate that this comparator is valid with respect to the type system. Note that all types and features used to define this comparator must come from the same type system. Note that this method only returns true or false. It doesn't tell you what's actually wrong. Maybe we need to change that?
        Specified by:
        isValid in interface FSIndexComparator
        Returns:
        true iff all key features are appropriate for the type of this comparator.
      • compareTo

        public int compareTo​(FSIndexComparator o)
        Compares two FSIndexComparator instances. The code to compare two FSs is in the compare method of FSLeafIndexImpl.
        Specified by:
        compareTo in interface java.lang.Comparable<FSIndexComparator>
