Function Documentation

make_filtered_iterator()

template<typename BaseIterator , typename Predicate >

FilteredIterator< BaseIterator > make_filtered_iterator	(	const BaseIterator &	i,
		const Predicate &	p
	)

Create an object of type FilteredIterator given the base iterator and predicate. This function makes the creation of temporary objects (for example as function arguments) a lot simpler because one does not have to explicitly specify the type of the base iterator by hand – it is deduced automatically here.

Note

This class, function, or variable is a template, and it can only be instantiated if the following condition is true:

(std::predicate<Predicate, BaseIterator>) 

If your compiler supports the C++20 standard, then this constraint will be enforced by a C++20 requires clause.
