Mojo::Transaction - Transaction Base Class

  use Mojo::Base 'Mojo::Transaction';

Mojo::Transaction is an abstract base class for transactions.

Mojo::Transaction implements the following attributes.

  my $connection = $tx->connection;
  $tx            = $tx->connection($connection);

Connection identifier or socket.

  my $keep_alive = $tx->keep_alive;
  $tx            = $tx->keep_alive(1);

Connection can be kept alive.

  my $kept_alive = $tx->kept_alive;
  $tx            = $tx->kept_alive(1);

Connection has been kept alive.

  my $local_address = $tx->local_address;
  $tx               = $tx->local_address($address);

Local interface address.

  my $local_port = $tx->local_port;
  $tx            = $tx->local_port($port);

Local interface port.

  my $cb = $tx->on_finish;
  $tx    = $tx->on_finish(sub {...});

Callback to be invoked when the transaction has been finished.

  $tx->on_finish(sub {
    my $self = shift;
  });

  my $cb = $tx->on_resume;
  $tx    = $tx->on_resume(sub {...});

Callback to be invoked whenever the transaction is resumed.

  my $previous = $tx->previous;
  $tx          = $tx->previous(Mojo::Transaction->new);

Previous transaction that triggered this followup transaction.

  my $remote_address = $tx->remote_address;
  $tx                = $tx->remote_address($address);

Remote interface address.

  my $remote_port = $tx->remote_port;
  $tx             = $tx->remote_port($port);

Remote interface port.

Mojo::Transaction inherits all methods from Mojo::Base and implements the following new ones.

  $tx = $tx->client_read($chunk);

Read and process client data.

  my $chunk = $tx->client_write;

Write client data.

  my $message          = $message->error;
  my ($message, $code) = $message->error;

Parser errors and codes.

  my $done = $tx->is_done;

Check if transaction is done.

  my $is_websocket = $tx->is_websocket;

Check if transaction is a WebSocket.

  my $writing = $tx->is_writing;

Check if transaction is writing.

  my $req = $tx->req;

Transaction request, usually a Mojo::Message::Request object.

  my $res = $tx->res;

Transaction response, usually a Mojo::Message::Response object.

  $tx = $tx->resume;

Resume transaction.

  $tx = $tx->server_close;

Transaction closed.

  $tx = $tx->server_read($chunk);

Read and process server data.

  my $chunk = $tx->server_write;

Write server data.

  my $res = $tx->success;

Returns the Mojo::Message::Response object (res) if transaction was successful or undef otherwise. Connection and parser errors have only a message in error, 400 and 500 responses also a code.

  if (my $res = $tx->success) {
    print $res->body;
  }
  else {
    my ($message, $code) = $tx->error;
    if ($code) {
      print "$code $message response.\n";
    }
    else {
      print "Connection error: $message\n";
    }
  }

Error messages can be accessed with the error method of the transaction object.
