NAME
Mojo::IOLoop::Stream - Non-blocking I/O stream
SYNOPSIS
use Mojo::IOLoop::Stream;
# Create stream
my $stream = Mojo::IOLoop::Stream->new($handle);
$stream->on(read => sub {
my ($stream, $chunk) = @_;
...
});
$stream->on(close => sub {
my $stream = shift;
...
});
$stream->on(error => sub {
my ($stream, $err) = @_;
...
});
# Start and stop watching for new data
$stream->start;
$stream->stop;DESCRIPTION
Mojo::IOLoop::Stream is a container for I/O streams used by Mojo::IOLoop.
EVENTS
Mojo::IOLoop::Stream can emit the following events.
close
$stream->on(close => sub {
my $stream = shift;
...
});Emitted safely if the stream gets closed.
drain
$stream->on(drain => sub {
my $stream = shift;
...
});Emitted safely once all data has been written.
error
$stream->on(error => sub {
my ($stream, $err) = @_;
...
});Emitted safely if an error happens on the stream.
read
$stream->on(read => sub {
my ($stream, $chunk) = @_;
...
});Emitted safely if new data arrives on the stream.
timeout
$stream->on(timeout => sub {
my $stream = shift;
...
});Emitted safely if the stream has been inactive for too long and will get closed automatically.
write
$stream->on(write => sub {
my ($stream, $chunk) = @_;
...
});Emitted safely if new data has been written to the stream.
ATTRIBUTES
Mojo::IOLoop::Stream implements the following attributes.
reactor
my $reactor = $stream->reactor;
$stream = $stream->reactor(Mojo::Reactor::Poll->new);Low level event reactor, defaults to the reactor attribute value of the global Mojo::IOLoop singleton.
timeout
my $timeout = $stream->timeout;
$stream = $stream->timeout(45);Maximum amount of time in seconds stream can be inactive before getting closed automatically, defaults to 15. Setting the value to 0 will allow this stream to be inactive indefinitely.
METHODS
Mojo::IOLoop::Stream inherits all methods from Mojo::EventEmitter and implements the following new ones.
new
my $stream = Mojo::IOLoop::Stream->new($handle);Construct a new Mojo::IOLoop::Stream object.
close
$stream->close;Close stream immediately.
handle
my $handle = $stream->handle;Get handle for stream.
is_readable
my $success = $stream->is_readable;Quick non-blocking check if stream is readable, useful for identifying tainted sockets.
is_writing
my $success = $stream->is_writing;Check if stream is writing.
start
$stream->start;Start watching for new data on the stream.
stop
$stream->stop;Stop watching for new data on the stream.
steal_handle
my $handle = $stream->steal_handle;Steal handle from stream and prevent it from getting closed automatically.
write
$stream = $stream->write('Hello!');
$stream = $stream->write('Hello!', sub {...});Write data to stream, the optional drain callback will be invoked once all data has been written.
