Name
SPVM::Go::UV::Loop - libuv Event Loop
Description
Go::UV::Loop class in SPVM represents an event loop in libuv.
Usage
use Go::UV::Loop;
use Go::UV::Constant as UV_C;
my $uv_loop = Go::UV::Loop->new;
$uv_loop->run(UV_C->UV_RUN_DEFAULT);Fields
uv_handles_h
has uv_handles_h : Hash of Go::UV::Handle;
A hash that holds active handles associated with this event loop.
Class Methods
new
static method new : Go::UV::Loop ();
Creates a new libuv loop.
Exceptions:
If uv_loop_init fails, an exception is thrown.=head1 Instance Methods
run
method run : int ($uv_run_mode : int);
Runs the event loop with the specified mode, and returns the return value of uv_run.
See Go::UV::Constant for constants such as UV_RUN_XXX specified at $uv_run_mode.
idle_init
method idle_init : void ($uv_idle : Go::UV::Handle::Idle);
Initializes an idle handle $uv_idle associated with the event loop. See uv_idle_init.
Exceptions:
$uv_idle must be defined. Otherwise an exception is thrown.
timer_init
method timer_init : void ($uv_timer : Go::UV::Handle::Timer);
Initializes a timer handle $uv_timer associated with the event loop. See uv_timer_init.
Exceptions:
$uv_timer must be defined. Otherwise an exception is thrown.
If uv_timer_init fails, an exception is thrown.
poll_init
method poll_init : void ($uv_poll : Go::UV::Handle::Poll, $fd : int);
Initializes a poll handle $uv_poll for the given file descriptor $fd associated with the event loop. See uv_poll_init.
Exceptions:
$uv_poll must be defined. Otherwise an exception is thrown.
If uv_poll_init fails, an exception is thrown.
Exceptions:
$uv_async must be defined. Otherwise an exception is thrown.
$cb must be defined. Otherwise an exception is thrown.
If uv_async_init fails, an exception is thrown.
async_init
method async_init : void ($uv_async : Go::UV::Handle::Async, $cb : Go::UV::Callback::Async);
Initializes an async handle $uv_async associated with the event loop with a callback $cb. Go::UV::Handle::Async#async_cb field is set to $cb. See uv_async_init.
Exceptions:
$uv_pipe must be defined. Otherwise an exception is thrown.
If uv_pipe_init fails, an exception is thrown.
pipe_init
method pipe_init : void ($uv_pipe : Go::UV::Handle::Pipe, $ipc : int);
Initializes a pipe handle $uv_pipe associated with the event loop with $ipc. See uv_pipe_init.
DESTROY
method DESTROY : void ();
Destroys the event loop and releases its resources. See uv_loop_close.
Exceptions:
If uv_loop_close fails, an exception is thrown.
