## Member Function Documentation

static const char* staticInterfaceName | ( |  | ) | `[inline, static]`

Returns the name of the interface "org.freedesktop.Telepathy.Channel.Type.StreamTube", which this class represents.

Returns:
  The D-Bus interface name.

QString Service | ( |  | ) | const`[inline]`

Getter for the remote object property "Service".

Don't use this: it blocks the main loop.

Returns:
  The value of the property, or a default-constructed value if the property is not readable.

Tp::SupportedSocketMap SupportedSocketTypes | ( |  | ) | const`[inline]`

Getter for the remote object property "SupportedSocketTypes".

Don't use this: it blocks the main loop.

Returns:
  The value of the property, or a default-constructed value if the property is not readable.

QDBusPendingReply Offer | ( | uint | addresstype,
|  | const QDBusVariant & | address,
|  | uint | accesscontrol,
|  | const QVariantMap & | parameters |
| ) |  |  | `[inline, slot]`

Begins a call to the D-Bus method "Offer" on the remote object.

Offer a stream tube exporting the local socket specified.

Parameters:

  | addresstype | The type of the listening address of the local service, as a member of Socket_Address_Type.
  | address | The listening address of the local service, as indicated by the address_type.
  | accesscontrol | The access control the local service applies to the local socket, specified so the connection manager can behave appropriately when it connects.
  | parameters | The dictionary of arbitrary Parameters to send with the tube offer.

QDBusPendingReply<QDBusVariant> Accept | ( | uint | addresstype,
|  | uint | accesscontrol,
|  | const QDBusVariant & | accesscontrolparam |
| ) |  |  | `[inline, slot]`

Begins a call to the D-Bus method "Accept" on the remote object.

Accept a stream tube that's in the "local pending" state. The connection manager will attempt to open the tube. The tube remains in the "local pending" state until the TubeChannelStateChanged signal is emitted.

Parameters:

  | addresstype | The type of address the connection manager should listen on.
  | accesscontrol |

The type of access control the connection manager should apply to the socket.

Note that if you plan to establish more than one connection through the tube, the Socket_Access_Control_Port access control can't be used as you can't connect more than once from the same port.

Parameters:

  | accesscontrolparam | A parameter for the access control type, to be interpreted as specified in the documentation for the Socket_Access_Control enum.

Returns:

The address on which the connection manager will listen for connections to this tube. The client should not attempt to connect to the address until the tube is open.

void NewRemoteConnection | ( | uint | handle,
|  | const QDBusVariant & | connectionParam,
|  | uint | connectionID |
| ) |  |  | `[signal]`

Represents the signal "NewRemoteConnection" on the remote object.

Emitted each time a participant opens a new connection to its socket.

This signal is only fired on the offering side.

Parameters:

  | handle | The handle of the participant who opened the new connection
  | connectionParam |

A parameter which can be used by the listening process to identify the connection. Note that this parameter has a meaningful value only in the Socket_Access_Control_Port and Socket_Access_Control_Credentials cases. If a different Socket_Access_Control has been chosen when offering the tube, this parameter should be ignored.

In the Socket_Access_Control_Port case, the variant contains a struct Socket_Address_IPv4 (or Socket_Address_IPv6) containing the address from which the CM is connected to the client application.

In the Socket_Access_Control_Credentials case, the variant contains the byte (D-Bus signature 'y') that has been sent with the credentials.

Parameters:

  | connectionID | The unique ID associated with this connection. This ID will be used to identifiy the connection when reporting errors with ConnectionClosed.

void NewLocalConnection | ( | uint | connectionID | ) | `[signal]`

Represents the signal "NewLocalConnection" on the remote object.

Emitted when the tube application connects to the CM's socket.

This signal is only fired on the accepting side.

Parameters:

  | connectionID | The unique ID associated with this connection. This ID will be used to identifiy the connection when reporting errors with ConnectionClosed.

void ConnectionClosed | ( | uint | connectionID,
|  | const QString & | error,
|  | const QString & | message |
| ) |  |  | `[signal]`

Represents the signal "ConnectionClosed" on the remote object.

Emitted when a connection has been closed.

Parameters:

  | connectionID | The ID of the connection.
  | error |

The name of a D-Bus error describing the error that occurred.

The following errors can be used:

- `org.freedesktop.Telepathy.Error.Cancelled`: user closed the socket or the tube.
- `org.freedesktop.Telepathy.Error.ConnectionLost`: the bytestream relaying connection's data has been broken.
- `org.freedesktop.Telepathy.Error.ConnectionRefused`: the tube offer refused the connection.

Parameters:

  | message | A debug message.

virtual void invalidate | ( | Tp::DBusProxy * | ,
|  | const QString & | ,
|  | const QString & |  |
| ) |  |  | `[protected, virtual]`

## Property Documentation

QString Service`[read]`

Represents property "Service" on the remote object.

A string representing the service name that will be used over the tube. It should be a well-known TCP service name as defined by http://www.iana.org/assignments/port-numbers or http://www.dns-sd.org/ServiceTypes.html, for instance "rsync" or "daap".

When the tube is offered, the service name is transmitted to the other end.

When requesting a channel with <tp:dbus-ref namespace="org.freedesktop.Telepathy">Connection.Interface.Requests.CreateChannel</tp:dbus-ref>, this property MUST be included in the request.

Tp::SupportedSocketMap SupportedSocketTypes`[read]`

Represents property "SupportedSocketTypes" on the remote object.

A mapping from address types (members of Socket_Address_Type) to arrays of access-control type (members of Socket_Access_Control) that the connection manager supports for stream tubes with that address type. For simplicity, if a CM supports offering a particular type of tube, it is assumed to support accepting it.

A typical value for a host without IPv6 support:

       {
         Socket_Address_Type_IPv4:
           [Socket_Access_Control_Localhost, Socket_Access_Control_Port,
            Socket_Access_Control_Netmask],
         Socket_Address_Type_Unix:
           [Socket_Access_Control_Localhost, Socket_Access_Control_Credentials]
       }

Connection Managers MUST support at least IPv4 with the localhost access control.

When requesting a channel with <tp:dbus-ref namespace="org.freedesktop.Telepathy">Connection.Interface.Requests.CreateChannel</tp:dbus-ref>, this property MUST NOT be included in the request.
