Event::generic

📦 max

A generic watcher: an event whenever Perl code says so. Events come from an event source, an Event::generic::Source object, whose event method gives every active watcher of the source an event; data passed to event reaches the callbacks as the event’s data. The events are Event::Event::Dataful objects.

use Event does not load this watcher type; use Event::generic does, and with it Event::generic::Source.

Event->generic(%attributes) (or Event::generic->new(...), or the source’s watch method) takes the shared attributes of Event::Watcher and source. A generic watcher repeats. It refuses to start without a callback or without a source (“without source”).

Synopsis

use Event;
use Event::generic;

my $source = Event::generic::Source->new;
my $w = $source->watch(cb => sub { print "got ", $_[0]->data, "\n" });
$source->event("hello");
Event::sweep();

Modules

• Event::generic::Source - An event source for generic watchers (see Event::generic): calling its event method gives an event to each of its active watchers.

Functions

Attributes

source

The event source watched: an Event::generic::Source, or undef for none. Anything else dies. Changing it moves an active watcher to the new source.
