14           while(1) {
15
16               # This inner loop will only iterate until there are no more
17               # changes available.
18               while (my $change = $stream->next) {

DESCRIPTION

24       This class models change stream results as returned by the "watch" in
25       MongoDB::Collection method.
26

STREAM METHODS

28   next
29           $change_stream = $collection->watch(...);
30           $change = $change_stream->next;
31
32       Waits for the next change in the collection and returns it.
33
34       Note: This method will wait for the amount of milliseconds passed as
35       "maxAwaitTimeMS" to "watch" in MongoDB::Collection or the server's
36       default wait-time. It will not wait indefinitely.
