      • getSet

        public final boolean getSet​(char[] src,
                            int srcStart)
        Fill in the given serialized set object.
        Parameters:
        src - pointer to start of array
        srcStart - pointer to start of serialized data (length value)
        Returns:
        true if the given array is valid, otherwise false

      • setToOne

        public final void setToOne​(int c)
        Set the USerializedSet to contain the given character (and nothing else).

      • getRange

        public final boolean getRange​(int rangeIndex,
                              int[] range)
        Returns a range of characters contained in the given serialized set.
        Parameters:
        rangeIndex - a non-negative integer in the range 0.. getSerializedRangeCount()-1
        range - variable to receive the data in the range
        Returns:
        true if rangeIndex is valid, otherwise false

      • contains

        public final boolean contains​(int c)
        Returns true if the given USerializedSet contains the given character.
        Parameters:
        c - the character to test for
        Returns:
        true if set contains c

      • countRanges

        public final int countRanges()
        Returns the number of disjoint ranges of characters contained in the given serialized set. Ignores any strings contained in the set.
        Returns:
        a non-negative integer counting the character ranges contained in set
