Inherits Tp::StreamTubeChannel.
The IncomingStreamTubeChannel class represents an incoming Telepathy channel of type StreamTube.
In particular, this class is meant to be used as a comfortable way for accepting incoming stream tubes. Tubes can be accepted as TCP and/or Unix sockets with various access control methods depending on what the service supports using the various overloads of acceptTubeAsTcpSocket() and acceptTubeAsUnixSocket().
Once a tube is successfully accepted and open (the PendingStreamTubeConnection returned from the accepting methods has finished), the application can connect to the socket the address of which can be retrieved from PendingStreamTubeConnection::ipAddress() and/or PendingStreamTubeConnection::localAddress() depending on which accepting method was used. Connecting to this socket will open a tunneled connection to the service listening at the offering end of the tube.
For more details, please refer to Telepathy specification.

| Tp::IncomingStreamTubeChannel::~IncomingStreamTubeChannel | ( | ) | [virtual] |
Class destructor.

Construct a new IncomingStreamTubeChannel object.
| connection | Connection owning this channel, and specifying the service. | |
| objectPath | The channel object path. | |
| immutableProperties | The channel immutable properties. | |
| coreFeature | The core feature of the channel type, if any. The corresponding introspectable should depend on IncomingStreamTubeChannel::FeatureCore. |

Create a new IncomingStreamTubeChannel object.

Reimplemented from Tp::StreamTubeChannel.
| PendingStreamTubeConnection * Tp::IncomingStreamTubeChannel::acceptTubeAsTcpSocket | ( | ) |
Accept an incoming stream tube as a TCP socket.
This method accepts an incoming connection request for a stream tube. It can be called only if the tube is in the TubeStateLocalPending state.
The connection manager will open a TCP socket for the application to connect to. The address of the socket will be returned in PendingStreamTubeConnection::ipAddress() once the operation has finished successfully.
Using this overload, the connection manager will accept every incoming connection from localhost.
This accept method must be supported by all connection managers adhering to the Telepathy specification.
This method requires IncomingStreamTubeChannel::FeatureCore to be ready.
| PendingStreamTubeConnection * Tp::IncomingStreamTubeChannel::acceptTubeAsTcpSocket | ( | const QHostAddress & | allowedAddress, | |
| quint16 | allowedPort | |||
| ) |
Accept an incoming stream tube as a TCP socket.
This method accepts an incoming connection request for a stream tube. It can be called only if the tube is in the TubeStateLocalPending state.
The connection manager will open a TCP socket for the application to connect to. The address of the socket will be returned in PendingStreamTubeConnection::ipAddress() once the operation has finished successfully.
This overload lets you specify an allowed address/port combination for connecting to the CM socket. Connections with other source addresses won't be accepted. The accessors supportsIPv4SocketsWithSpecifiedAddress() and supportsIPv6SocketsWithSpecifiedAddress() can be used to verify that the connection manager supports this kind of access control; otherwise, this method will always fail unless QHostAddress::Any or QHostAddress::AnyIPv6 is passed, in which case the behavior is identical to the always supported acceptTubeAsTcpSocket() overload.
Note that when using QHostAddress::Any or QHostAddress::AnyIPv6, allowedPort is ignored.
This method requires IncomingStreamTubeChannel::FeatureCore to be ready.
| allowedAddress | An allowed address for connecting to the socket. | |
| allowedPort | An allowed port for connecting to the socket. |
| PendingStreamTubeConnection * Tp::IncomingStreamTubeChannel::acceptTubeAsUnixSocket | ( | bool | requireCredentials = false |
) |
Accept an incoming stream tube as a Unix socket.
This method accepts an incoming connection request for a stream tube. It can be called only if the tube is in the TubeStateLocalPending state.
An Unix socket (can be used with QLocalSocket or alike) will be opened by the connection manager as the local tube endpoint. This is only supported if supportsUnixSocketsOnLocalhost() is true.
You can also specify whether the CM should require an SCM_CREDS or SCM_CREDENTIALS message upon connection instead of accepting every incoming connection from localhost. This provides additional security, but requires sending the byte retrieved from PendingStreamTubeConnection::credentialByte() in-line in the socket byte stream (in a credentials message if available on the platform), which might not be compatible with all protocols or libraries. Also, only connection managers for which supportsUnixSocketsWithCredentials() is true support this type of access control.
This method requires IncomingStreamTubeChannel::FeatureCore to be ready.
| requireCredentials | Whether the CM should require an SCM_CREDS or SCM_CREDENTIALS message upon connection. |
| QPair< QHostAddress, quint16 > Tp::IncomingStreamTubeChannel::ipAddress | ( | ) | const |
Return the IP address/port combination of the opened stream tube.
Calling this method when the tube has not been opened will cause it to return an undefined value. The same will happen if the tube has been accepted as an Unix socket. Use localAddress() if that is the case.
Reimplemented from Tp::StreamTubeChannel.
| QString Tp::IncomingStreamTubeChannel::localAddress | ( | ) | const |
Return the local address of the opened stream tube.
Calling this method when the tube has not been opened will cause it to return an undefined value. The same will happen if the tube has been accepted as a TCP socket. Use ipAddress() if that is the case.
Reimplemented from Tp::StreamTubeChannel.
const Feature Tp::IncomingStreamTubeChannel::FeatureCore [static] |
Feature representing the core that needs to become ready to make the IncomingStreamTubeChannel object usable.
This is currently the same as StreamTubeChannel::FeatureCore, but may change to include more.
When calling isReady(), becomeReady(), this feature is implicitly added to the requested features.
Reimplemented from Tp::StreamTubeChannel.
