BLBitSetWordIterator Class Referencefinal
BitSet word iterator [C++ API].
Low-level iterator that sees a BitSet as an array of bit words. It only iterates non-zero words and returns zero at the end of iteration.
A simple way of printing all non-zero words of a BitWord:
BLBitSet set;
set.addRange(100, 200);
BLBitSetWordIterator it(set);
while (uint32_t bits = it.nextWord()) {
printf("{WordIndex: %u, WordData: %08X }\n", it.wordIndex(), bits);
}

Iterator Interface
BLBitSetWordIterator::BLBitSetWordIterator()noexcept[1/3][¶]
Creates a default constructed iterator, not initialized to iterate any BitSet.
BLBitSetWordIterator::BLBitSetWordIterator(const BLBitSetCore& bitSet)noexcept[2/3][¶]
Creates an iterator, that will iterate the given bitSet.
- Note
- The
bitSetcannot change or be destroyed during iteration.
BLBitSetWordIterator::BLBitSetWordIterator(const BLBitSetWordIterator& other)defaultnoexcept[3/3][¶]
Creates a copy of other iterator.
void BLBitSetWordIterator::reset()noexcept[1/2][¶]
Resets the iterator (puts it into a default constructed state).
void BLBitSetWordIterator::reset(const BLBitSetCore& bitSet)noexcept[2/2][¶]
Reinitializes the iterator to iterate the given bitSet, from the beginning.
uint32_t BLBitSetWordIterator::nextWord()noexcept[¶]
Returns the next (or the first, if called the first time) non-zero word of the BitSet or zero if the iteration ended.
Use wordIndex() to get the index (in word units) of the word returned.
uint32_t BLBitSetWordIterator::bitIndex() constnoexcept[¶]
Returns the current bit index of a word returned by nextWord().
uint32_t BLBitSetWordIterator::wordIndex() constnoexcept[¶]
Returns the current word index of a word returned by nextWord().
