Class mata::utils::SynchronizedExistentialIterator

template<typename Iterator>
class SynchronizedExistentialIterator : public mata::utils::SynchronizedIterator<Iterator>

Public Functions

inline virtual bool advance() override

Advances all positions just above current_minimum, that is, to or above next_minimum.

Those at next_minimum are added to currently_synchronized. Since next_minimum becomes the current minimum, new next_minimum must be updated too.

inline virtual const std::vector<Iterator> &get_current() const override

Returns the vector of current still active positions.

Beware, they will be ordered differently from how there were input into the iterator. This is due to swapping of the emptied positions with positions at the end.

inline virtual void push_back(const Iterator &begin, const Iterator &end) override

This is supposed to be called only before an iteration, after constructor of reset.

Calling after advance breaks the iterator. Specifies begin and end of one vector, to initialise before the iteration starts.

inline virtual void reset(const size_t size = 0) override

Empties positions and ends.

Though they should keep the allocated space.

Parameters:

size – Number of elements to reserve up-front for positions and ends.
