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.
METHODS
scalar = $iter->next
