Reducing the data packet size reduces the latency. Also ,bitwise, operators are very fast for the cpu to process. For ,Java, Script, I'd probably not bother with bitmasks and ,bitwise, operators, but if you are using c or c++ and trying to minimize the amount of memory you're using, bit ,masks, will always beat bool.

The ,bitwise, operation can be used just like any other operator in ,Java,. The only difference between it and other operations is that it evaluates in a bit-by-bit value. On occasion, one may combine the ,bitwise, operation with other binary operators. However, note that ,bitwise, operators only work with integral types: byte, char, short, int, and long.

6/2/2018, · Java defines several bitwise operators, which can be applied to the integer types, long, int, short, char, and byte. Bitwise operator works on bits and performs the bit-by-bit operation. Assume if a = 60 and b = 13; now in binary format they will be as follows −. a = 0011 1100 b = 0000 1101 ----------------- a&b = 0000 1100 a|b = 0011 1101 a^b = ...

5/6/2020, · Two notes here: First, std::bitset doesn’t have a nice function that allows you to query bits using a bit ,mask,. So if you want to use bit ,masks, rather than positional indexes, you’ll have to use ,Bitwise, AND to query bits. Second, we make use of the any() function, which returns true if any bits are set, and false otherwise to see if the bit we queried remains on or off.

The same logic follows when we want to toggle bits. We still use bitmasks to select the bits we're interested in, but we use the XOR bitwise operator (^) instead of the AND bitwise operator (&) for our query. Let's say we wanted to toggle the canSendTelemetry property. We know that it is located in the first bit from the right.
