Web(1) all bits Flips all bits in the bitset. (2) single bit Flips the bit at position pos. Parameters pos Order position of the bit whose value is flipped. Order positions are counted from the rightmost bit, which is order position 0. If pos is equal or greater than the bitset size, an out_of_range exception is thrown. http://duoduokou.com/scala/33778779458029942208.html

WebFor example, if you take a BitSet and set the bit at position 1,000,000 to true and you have just over 100kB. That’s over 100kB to store the position of one bit. This is wasteful even if you do not care about memory: suppose that you need to compute the intersection between this BitSet and another one that has a bit at position 1,000,001 to ... WebReturns an unsigned long with the integer value that has the same bits set as the bitset. If the bitset size is too big to be represented in a value of type unsigned long, the function throws an exception of type overflow_error.
