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¶
