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->write('Hello!');
  $stream->write('Hello!', sub {...});

Write data to stream, the optional drain callback will be invoked once all data has been written.
