Bitset operations
WebMay 18, 2015 · However, bitset also has other operators, such as operator &=, operator <<=, etc., which operates on the full width of the bitset. Because the underlying machinery can often operate on 32-bit, 64-bit and sometimes 128-bit (with SIMD) at a time (in the same number of CPU cycles), code that is designed to take advantage of such multi-bit ... WebThe bits of a BitSet are indexed by nonnegative integers. Individual indexed bits can be examined, set, or cleared. One BitSet may be used to modify the contents of another BitSet through logical AND, logical inclusive OR, and logical exclusive OR operations. By default, all bits in the set initially have the value false.
