GStreamer::Iterator(3)User Contributed Perl DocumentatioGStreamer::Iterator(3) NAME GStreamer::Iterator SYNOPSIS foreach ($bin -> iterate_elements()) { do_something($_); } my $iter = $bin -> iterate_elements(); while ($_ = $iter -> next()) { do_something($_); } DESCRIPTION There are two ways to use a GStreamer::Iterator. The first is to use normal Perl looping stuff: foreach ($bin -> iterate_elements()) { do_something($_); } This is very elegant and Perl-ish, but may also be a bit slower. The alternative is to use the next method: my $iter = $bin -> iterate_elements(); while ($_ = $iter -> next()) { do_something($_); } This is hardly beautiful but avoids looping over the elements unnecessarily and is thus faster.
