GStreamer::Iterator - Object to retrieve multiple elements in a threadsafe way.
=cut
=for position SYNOPSIS
=head1 SYNOPSIS
foreach ($bin -> iterate_elements()) {
do_something($_);
}
my $iter = $bin -> iterate_elements();
while ($_ = $iter -> next()) {
do_something($_);
}
=cut
=for position DESCRIPTION
=head1 DESCRIPTION
There are two ways to use a I<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 I<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.
