R.BITOP

Category	Description
Syntax	`R.BITOP <AND, OR, XOR, NOT, ANDOR, ONE> destkey key [key1 key2 ... keyN]`
Time complexity	O(C)
Supports structures	Bitmap32
Command description	Performs set operations on Roaring Bitmaps and stores the result in destkey.

Parameter

operation: The type of set operation.
destkey: The destination key that stores the result (Roaring data structure).
key: The key of the Roaring data structure. You can specify multiple keys.

If the operation is successful, the integer number of bits in the result that are set to 1 is returned.
Otherwise, an error message is returned.

The valid forms to call the command are:

R.BITOP AND destkey srckey1 srckey2 srckey3 ... srckeyN
A bit in destkey is set only if it is set in all source bitmaps.
R.BITOP OR destkey srckey1 srckey2 srckey3 ... srckeyN
A bit in destkey is set if it is set in at least one source bitmap.
R.BITOP XOR destkey srckey1 srckey2 srckey3 ... srckeyN
Mostly used with two source bitmaps. A bit in destkey is set only if its value differs between the two source bitmaps.
R.BITOP NOT destkey srckey
NOT is a unary operator and only supports a single source bitmap. Sets each bit to the inverse of its value in the source bitmap.
R.BITOP DIFF destkey X [Y1 Y2 ...]
A bit in destkey is set if it is set in X, but not in any of Y1, Y2, ... ( X - (Y1 ∪ Y2 ∪ ...)).
R.BITOP DIFF1 destkey X [Y1 Y2 ...]
A bit in destkey is set if it is set in one or more of Y1, Y2, ..., but not in X ... ((Y1 ∪ Y2 ∪ ...) - X).
R.BITOP ANDOR destkey X [Y1 Y2 ...]
A bit in destkey is set if it is set in X and also in one or more of Y1, Y2, ... (X ∩ (Y1 ∪ Y2 ∪ ...)).
R.BITOP ONE destkey X1 [X2 X3 ...]
A bit in destkey is set if it is set in exactly one of X1, X2, ... (symmetric difference for multiple sets).
