Member Function Documentation

◆ staticInterfaceName()

static QLatin1String Tp::Client::ConnectionInterfaceRequestsInterface::staticInterfaceName ( )
inlinestatic

Returns the name of the interface "org.freedesktop.Telepathy.Connection.Interface.Requests", which this class represents.

Returns
The D-Bus interface name.

◆ requestPropertyChannels()

Tp::PendingVariant* Tp::Client::ConnectionInterfaceRequestsInterface::requestPropertyChannels ( ) const
inline

Asynchronous getter for the remote object property Channels of type Tp::ChannelDetailsList.

A list of all the channels which currently exist on this connection. Change notification is via the NewChannels and ChannelClosed signals.

Returns
A pending variant which will emit finished when the property has been retrieved.

◆ requestPropertyRequestableChannelClasses()

Tp::PendingVariant* Tp::Client::ConnectionInterfaceRequestsInterface::requestPropertyRequestableChannelClasses ( ) const
inline

Asynchronous getter for the remote object property RequestableChannelClasses of type Tp::RequestableChannelClassList.

The classes of channel that are expected to be available on this connection, i.e. those for which CreateChannel() can reasonably be expected to succeed. User interfaces can use this information to show or hide UI components.

This property cannot change after the connection has gone to state Connection_Status_Connected, so there is no change notification (if the connection has context-dependent capabilities, it SHOULD advertise support for all classes of channel that it might support during its lifetime). Before this state has been reached, the value of this property is undefined.

This is not on an optional interface, because connection managers can always offer some sort of clue about the channel classes they expect to support (at worst, they can announce support for everything for which they have code).

Returns
A pending variant which will emit finished when the property has been retrieved.

◆ requestAllProperties()

Tp::PendingVariantMap* Tp::Client::ConnectionInterfaceRequestsInterface::requestAllProperties ( ) const
inline

Request all of the DBus properties on the interface.

Returns
A pending variant map which will emit finished when the properties have been retrieved.

◆ CreateChannel

QDBusPendingReply<QDBusObjectPath, QVariantMap> Tp::Client::ConnectionInterfaceRequestsInterface::CreateChannel ( const QVariantMap &  request,
int  timeout = -1 
)
inlineslot

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

Request that an entirely new channel is created.

There is deliberately no flag corresponding to the suppress_handler argument to ConnectionInterface::RequestChannel() , because passing a FALSE value for that argument is deprecated. Requests made using this interface always behave as though suppress_handler was TRUE.

Note that timeout is ignored as of now. It will be used once http://bugreports.qt.nokia.com/browse/QTBUG-11775 is fixed.

Parameters
request
\htmlonly
<p>A dictionary containing desirable properties, which MUST include
   \endhtmlonly \link ChannelInterface::requestPropertyChannelType() ChannelInterface::ChannelType \endlink \htmlonly .
  Some properties
  are defined such that only an exact match makes sense, and
  connection managers MUST NOT satisfy a request with a channel
  where that property does not match; some properties are defined
  such that the connection manager MAY treat the request as merely
  a hint, and make a best-effort attempt to satisfy it. This is
  documented separately for each property.</p>

<p>If this dictionary contains a property whose semantics
  are not known to the connection manager, this method MUST fail
  without side-effects (in particular it must not create a new
  channel).</p>

<div class="rationale">
  <p>This is necessary if we want to be able to invent properties
    in future that, when used in a request, are hard requirements
    rather than just hints. A connection manager that did not know
    the semantics of those properties could incorrectly return a
    new channel that did not satisfy the requirements.</p>
</div>

<p>The connection manager MUST NOT respond successfully,
  and SHOULD NOT create a new channel or cause any other
  side-effects, unless it can create a new channel that satisfies
  the client's requirements.</p>

<p>Properties that will be set by this argument need not have write
  access after the channel has been created - indeed, it is
  expected that most will be read-only.</p>
\endhtmlonly
timeoutThe timeout in milliseconds.
Returns
\htmlonly
<p>The Channel object, which MUST NOT be signalled with
   \endhtmlonly NewChannels() \htmlonly  until after this method
  returns.</p>

<div class="rationale">
  <p>This allows the requester to alter its handling of
    NewChannels by knowing whether one of the channels satisfied
    a request it made.</p>
</div>
\endhtmlonly
\htmlonly
<p>Properties of the channel that was produced, equivalent to
  the properties in <tp:type>Channel_Details</tp:type>.
  Connection managers MUST NOT include properties here whose
  values can change, for the same reasons as in
  <tp:type>Channel_Details</tp:type>.</p>
\endhtmlonly

◆ EnsureChannel

QDBusPendingReply<bool, QDBusObjectPath, QVariantMap> Tp::Client::ConnectionInterfaceRequestsInterface::EnsureChannel ( const QVariantMap &  request,
int  timeout = -1 
)
inlineslot

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

Request that channels are ensured to exist.

The connection manager is in the best position to determine which existing channels could satisfy which requests.

Note that timeout is ignored as of now. It will be used once http://bugreports.qt.nokia.com/browse/QTBUG-11775 is fixed.

Parameters
request
\htmlonly
<p>A dictionary containing desirable properties, with the same
  semantics as the corresponding parameter to
   \endhtmlonly CreateChannel() \htmlonly .</p>
\endhtmlonly
timeoutThe timeout in milliseconds.
Returns
\htmlonly
<p>If false, the caller of EnsureChannel MUST assume that some
  other process is handling this channel; if true, the caller of
  EnsureChannel SHOULD handle it themselves or delegate it to another
  client.</p>

<p>If the creation of a channel makes several calls to EnsureChannel
  (and no other requests) successful, exactly one of those calls MUST
  return a true value for this argument.</p>

<p>If the creation of a channel makes other requests successful,
  the value returned for this argument MUST be such that exactly
  one of the clients making requests ends up responsible for the
  channel. In particular, if
   \endhtmlonly CreateChannel() \htmlonly  returns a channel
  <em>C</em>, any EnsureChannel calls that also return <em>C</em>
  MUST return a false value for this argument.</p>
\endhtmlonly
The Channel object. If it was created as a result of this method 
call, it MUST NOT be signalled by NewChannels until after this 
method returns. This allows the requester to alter its handling of 
NewChannels by knowing whether one of the channels satisfied a 
request it made.
\htmlonly
<p>Properties of the channel that was produced, equivalent to
  the properties in <tp:type>Channel_Details</tp:type>.
  Connection managers MUST NOT include properties here whose
  values can change, for the same reasons as in
  <tp:type>Channel_Details</tp:type>.</p>
\endhtmlonly

◆ NewChannels

void Tp::Client::ConnectionInterfaceRequestsInterface::NewChannels ( const Tp::ChannelDetailsList channels)
signal

Represents the signal NewChannels on the remote object.

New channels have been created. The connection manager SHOULD emit a single signal for any group of closely related channels that are created at the same time, so that the channel dispatcher can try to dispatch them to a handler as a unit.

In particular, if additional channels are created as a side-effect of a call to CreateChannel() , these channels SHOULD appear in the same NewChannels signal as the channel that satisfies the request.

Joining a MUC Tube in XMPP requires joining the corresponding MUC (chatroom), so a ChannelTypeTextInterface channel can be created as a side-effect.

Every time NewChannels is emitted, it MUST be followed by a ConnectionInterface::NewChannel() signal for each channel.

The double signal emission is for the benefit of older Telepathy clients, which won't be listening for NewChannels.

The more informative NewChannels signal comes first so that clients that did not examine the connection to find out whether Requests is supported will see the more informative signal for each channel first, and then ignore the less informative signal because it announces a new channel of which they are already aware.

Parameters
channels
The channels and their details. All channels that are signalled 
together like this MUST have the same Bundle property, which may 
either refer to an existing bundle, or establish a new bundle.

◆ ChannelClosed

void Tp::Client::ConnectionInterfaceRequestsInterface::ChannelClosed ( const QDBusObjectPath &  removed)
signal

Represents the signal ChannelClosed on the remote object.

Emitted when a channel is closed and hence disappears from the Channels property. This is redundant with the Closed signal on the channel itself, but it does provide full change notification for the Channels property.

Parameters
removed
The channel which has been removed from the Channels property

◆ invalidate()

void Tp::Client::ConnectionInterfaceRequestsInterface::invalidate ( Tp::DBusProxy proxy,
const QString &  error,
const QString &  message 
)
protectedvirtual

Reimplemented from Tp::AbstractInterface.
