      Sets or clears the bit at offset in the string value stored at key.
      Specified by:
      setbit in interface BitMapCommands<K>
      Parameters:
      key - the key.
      offset - the offset
      value - the value (O or 1)

      the original bit value stored at offset, 0 or 1.

    • bitcount

      public long bitcount(K key)
      Description copied from interface: BitMapCommands

      Specified by:
      bitcount in interface BitMapCommands<K>
      Parameters:

      Returns:
      the number of bits set to 1 in the stored string.

    • bitcount

      public long bitcount(K key, long start, long end)
      Description copied from interface: BitMapCommands
      Execute the command BITCOUNT. Summary: Count set bits in a string Group: bitmap Requires Redis 2.6.0
      Specified by:
      bitcount in interface BitMapCommands<K>
      Parameters:
      key - the key
      start - the start index
      end - the end index
      Returns:
      the number of bits set to 1 in the stored string.

    • bitfield

      public List<Long> bitfield(K key, BitFieldArgs bitFieldArgs)
      Description copied from interface: BitMapCommands
      Execute the command BITFIELD. Summary: Perform arbitrary bitfield integer operations on strings Group: bitmap Requires Redis 3.2.0
      Specified by:
      bitfield in interface BitMapCommands<K>
      Parameters:
      key - the key
      Returns:
      the results from the bitfield commands as described on https://redis.io/commands/bitfield/.

    • bitpos

      public long bitpos(K key, int bit)
      Description copied from interface: BitMapCommands
      Execute the command BITPOS. Summary: Find first bit set or clear in a string Group: bitmap Requires Redis 2.8.7
      Specified by:
      bitpos in interface BitMapCommands<K>
      Parameters:
      key - the key
      bit - 1 to look for 1, 0 to look for 0
      Returns:
      the position of the first bit set to 1 or 0 according to the request. If we look for set bits (the bit argument is 1) and the string is empty or composed of just zero ints, -1 is returned. If we look for clear bits (the bit argument is 0) and the string only contains bit set to 1, the function returns the first bit not part of the string on the right. So if the string is three ints set to the value 0xff the command BITPOS key 0 will return 24, since up to bit 23 all the bits are 1. Basically, the function considers the right of the string as padded with zeros if you look for clear bits and specify no range or the start argument only. However, this behavior changes if you are looking for clear bits and specify a range with both start and end. If no clear bit is found in the specified range, the function returns -1 as the user specified a clear range and there are no 0 bits in that range.

    • bitpos

      public long bitpos(K key, int bit, long start)
      Description copied from interface: BitMapCommands
      Execute the command BITPOS. Summary: Find first bit set or clear in a string Group: bitmap Requires Redis 2.8.7
      Specified by:
      bitpos in interface BitMapCommands<K>
      Parameters:
      key - the key
      bit - 1 to look for 1, 0 to look for 0
      start - the start position
      Returns:
      the position of the first bit set to 1 or 0 according to the request. If we look for set bits (the bit argument is 1) and the string is empty or composed of just zero ints, -1 is returned. If we look for clear bits (the bit argument is 0) and the string only contains bit set to 1, the function returns the first bit not part of the string on the right. So if the string is three ints set to the value 0xff the command BITPOS key 0 will return 24, since up to bit 23 all the bits are 1. Basically, the function considers the right of the string as padded with zeros if you look for clear bits and specify no range or the start argument only. However, this behavior changes if you are looking for clear bits and specify a range with both start and end. If no clear bit is found in the specified range, the function returns -1 as the user specified a clear range and there are no 0 bits in that range.
