GStreamer::Iterator(3pm)
NAME
GStreamer::Iterator - Object to retrieve multiple elements in a
threadsafe way.
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
