Mojo::IOLoop::Stream(3)

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, $bytes) = @_;
    ...
  });
  $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;

  # Start reactor if necessary
  $stream->reactor->start unless $stream->reactor->is_running;

DESCRIPTION
Mojo::IOLoop::Stream is a container for I/O streams used by Mojo::IOLoop.

EVENTS
Mojo::IOLoop::Stream inherits all events from Mojo::EventEmitter and can emit the following new ones.

  close
  $stream->on(close => sub {
    my $stream = shift;
    ...
  });

Emitted if the stream gets closed.

  drain
  $stream->on(drain => sub {
    my $stream = shift;
    ...
  });

Emitted once all data has been written.

  error
  $stream->on(error => sub {
    my ($stream, $err) = @_;
    ...
  });

Emitted if an error occurs on the stream, fatal if unhandled.

  read
  $stream->on(read => sub {
    my ($stream, $bytes) = @_;
    ...
  });

Emitted if new data arrives on the stream.

  timeout
  $stream->on(timeout => sub {
    my $stream = shift;
    ...
  });

Emitted if the stream has been inactive for too long and will get closed automatically.

  write
  $stream->on(write => sub {
    my ($stream, $bytes) = @_;
    ...
  });

Emitted 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.

METHODS
Mojo::IOLoop::Stream inherits all methods from Mojo::EventEmitter and implements the following new ones.

  close
  $stream->close;

Close stream immediately.

  close_gracefully
  $stream->close_gracefully;

Close stream gracefully.

  handle
  my $handle = $stream->handle;

Get handle for stream, usually an IO::Socket::IP or IO::Socket::SSL object.

  is_readable
  my $bool = $stream->is_readable;

Quick non-blocking check if stream is readable, useful for identifying tainted sockets.

  is_writing
  my $bool = $stream->is_writing;

Check if stream is writing.

  new
  my $stream = Mojo::IOLoop::Stream->new($handle);

Construct a new Mojo::IOLoop::Stream object.

  start
  $stream->start;

Start or resume watching for new data on the stream.

  steal_handle
  my $handle = $stream->steal_handle;

Steal "handle" and prevent it from getting closed automatically.

  stop
  $stream->stop;

Stop watching for new data on the stream.

  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.

  write
  $stream = $stream->write($bytes);
  $stream = $stream->write($bytes => sub {...});

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