      • NumberSet

        NumberSet​(long start,
          long end)
        Constructs a new NumberSet containing all values within the specified range (inclusive).

                  java.util.BitSet bitset)

    • Method Detail

      • copy

        NumberSet copy()
        Returns a new copy of this NumberSet.

      • get

        boolean get​(long value)
        Returns true if the given value is set, else false.

      • clear

        void clear​(long fromValue,
           long toValue)
        Unsets all values between the given fromValue (inclusive) and toValue (inclusive).

        NOTE: Unlike java.util.BitSet.clear(int, int) both values are *inclusive*.

      • clear

        void clear​(long not)
        Unsets (i.e. remove from this NumberSet) the given value.

      • nextSetValue

        long nextSetValue​(long value)

        Parameters:
        value - fromIndex the index to start checking from (inclusive)
        Returns:
        the value that occurs on or after the specified value, or start - 1 is no such value

      • previousSetValue

        long previousSetValue​(long value)
        Returns the value that occurs on or before the specified value.
        Parameters:
        value - fromIndex the index to start checking from (inclusive)
        Returns:
        the value that occurs on or after the specified value, or start - 1 is no such value
