Method Detail

setbit

public int setbit(K key,
                  long offset,
                  int value)

Description copied from interface: BitMapCommands

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)

Returns:

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

bitcount

public long bitcount(K key)

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

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.

bitpos

public long bitpos(K key,
                   int bit,
                   long start,
                   long end)

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 - true to look for 1, false to look for 0

start - the start position

end - the end 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.
