Detailed Description
template<typename WrappedIteratorT, typename PredicateT>
class llvm::filter_iterator< WrappedIteratorT, PredicateT >
An iterator adaptor that filters the elements of given inner iterators.
The predicate parameter should be a callable object that accepts the wrapped iterator's reference type and returns a bool. When incrementing or decrementing the iterator, it will call the predicate on each element and skip any where it returns false.
int A[] = { 1, 2, 3, 4 };
// R contains { 1, 3 }.
