    • NumberSet

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

  • Method Details

    • 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)

      Returns the value that occurs on or after 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

    • 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
