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.
