AnyEvent::FTP::Client::Transfer - Transfer class for asynchronous ftp client
version 0.19
use AnyEvent::FTP::Client;
my $client = AnyEvent::FTP::Client;
$client->connect('ftp://ftp.cpan.org')->cb(sub {
# $upload_transfer and $download_transfer are instances of
# AnyEvent::FTP::Client::Transfer
my $upload_transfer = $client->stor('remote_filename.txt', 'content');
my $buffer;
my $download_transfer = $client->retr('remote_filename.txt', \$buffer);
});
This class represents a file transfer with a remote server. Transfers may be initiated between a remote file name and a local object. The local object may be a regular scalar, reference to a scalar or a file handle, for details, see the stor, stou, appe and retr methods in AnyEvent::FTP::Client.
This documentation covers what you can do with the transfer object once it has been initiated.
This class consumes these roles:
This class provides these events:
Emitted when the data connection is opened, and passes in as its first argument the AnyEvent::Handle instance used to transfer the file.
$xfer->on_open(sub {
my($handle) = @_;
# $handle isa AnyEvent::Handle
});
Emitted when the transfer is complete, either due to a successful transfer or the server returned a failure status. Passes in the final AnyEvent::FTP::Client::Response message associated with the transfer.
$xfer->on_close(sub {
my($res) = @_;
# $res isa AnyEvent::FTP::Client::Response
});
Emitted when the data connection closes.
$xfer->on_eof(sub {
# no args passed in
});
Register a callback with the transfer to be executed when the transfer successfully completes, or fails. Works exactly like the AnyEvent condition variable cb method.
Returns true if the transfer has completed (either successfully or not). If true, then it is safe to call recv to retrieve the response (Some event loops do not support calling recv before there is a message waiting).
Retrieve the AnyEvent::FTP::Client::Response object.
For STOU transfers ONLY, this returns the remote file name.
