Detailed Description

Iterate over the positive positions one at a time.

A positive position is the position where a bit is 1.

This class iterates over all the positive positions. Immediately after initialization, the "current" bit is the first bit that is 1.

Member Function Documentation

ibis::bitvector::word_t ibis::bitvector::pit::operator* ( ) const

inline

Operator to retrieve the position of the current bit.

It returns the current position or 0xFFFFFFFFU when there is no bit to report or the object is not initialized.

void ibis::bitvector::pit::skip ( unsigned  k )

inline

Skip over next k positive positions.

It is equivalent to call the function next k times.
