Class: MappedIterator - X-Ref
Convenience class for generating iterators from iterators.| __construct( $iter, $vCallback, array $options = array() X-Ref |
| Build an new iterator from a base iterator by having the former wrap the later, returning the result of "value" callback for each current() invocation. The callback takes the result of current() on the base iterator as an argument. The keys of the base iterator are reused verbatim. An "accept" callback can also be provided which will be called for each value in the base iterator (post-callback) and will return true if that value should be included in iteration of the MappedIterator (otherwise it will be filtered out). param: Iterator|Array $iter param: callable $vCallback Value transformation callback param: array $options Options map (includes "accept") (since 1.22) |
