GStreamer::Iterator
foreach ($bin -> iterate_elements()) { do_something($_); } my $iter = $bin -> iterate_elements(); while ($_ = $iter -> next()) { do_something($_); }
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.
