Event::RPC::Loop::Event - Event mainloop for Event::RPC
SYNOPSIS
use Event::RPC::Server;
use Event::RPC::Loop::Event;
my $server = Event::RPC::Server->new (
...
loop => Event::RPC::Loop::Event->new(),
...
);
$server->start;
DESCRIPTION
This modules implements a mainloop using the Event module for the Event::RPC::Server module. It implements the interface of
Event::RPC::Loop. Please refer to the manpage of Event::RPC::Loop for details.

Event::RPC::Loop - Mainloop Abstraction layer for Event::RPC
SYNOPSIS
use Event::RPC::Server;
use Event::RPC::Loop::Glib;
my $server = Event::RPC::Server->new (
...
loop => Event::RPC::Loop::Glib->new(),
...
);
$server->start;
DESCRIPTION
This modules defines the interface of Event::RPC's mainloop abstraction layer. It's a virtual class all mainloop modules should inherit
from.
INTERFACE
The following methods need to be implemented:
$loop->enter ()
Enter resp. start a mainloop.
$loop->leave ()
Leave the mainloop, which was started with the enter() method.
$watcher = $loop->add_io_watcher ( %options )
Add an I/O watcher. Options are passed as a hash of key/value pairs. The following options are known:
fh The filehandle to be watched.
cb This callback is called, without any parameters, if an event occured on the filehandle above.
desc
A description of the watcher. Not necessarily implemented by all modules, so it may be ignored.
poll
Either 'r', if your program reads from the filehandle, or 'w' if it writes to it.
A watcher object is returned. What this exactly is depends on the implementation, so you can't do anything useful with it besides
passing it back to del_io_watcher().
$loop->del_io_watcher ( $watcher )
Deletes an I/O watcher which was added with $loop->add_io_watcher().
$timer = $loop->add_timer ( %options )
This sets a timer, a subroutine called after a specific timeout or on a regularly basis with a fixed time interval.
Options are passed as a hash of key/value pairs. The following options are known:
interval
A time interval in seconds, may be fractional.
after
Callback is called once after this amount of seconds, may be fractional.
cb The callback.
desc
A description of the timer. Not necessarily implemented by all modules, so it may be ignored.
A timer object is returned. What this exactly is depends on the implementation, so you can't do anything useful with it besides passing
it back to del_io_timer().
$loop->del_timer ( $timer )
Deletes a timer which was added with $loop->add_timer().
DIRECT USAGE IN YOUR SERVER
You may use the methods of Event::RPC::Loop by yourself if you like. This way your program keeps independent of the actual mainloop module
in use, if the simplified interface of Event::RPC::Loop is sufficient for you.
In your server program you access the actual mainloop object this way:
my $loop = Event::RPC::Server->instance->get_loop;
Naturally nothing speaks against making your program to work only with a specific mainloop implementation, if you need its features. In
that case you may use the corresponding API directly (e.g. of Event or Glib), no need to access it through Event::RPC::Loop.
