QString Telepathy::Client::ChannelInterface::ChannelType | ( | ) | const [inline] |
Getter for the remote object property "ChannelType".
Don't use this: it blocks the main loop.
QDBusPendingReply Telepathy::Client::ChannelInterface::Close | ( | ) | [inline, slot] |
Begins a call to the D-Bus method "Close" on the remote object.
Request that the channel be closed. This is not the case until the Closed signal has been emitted, and depending on the connection manager this may simply remove you from the channel on the server, rather than causing it to stop existing entirely. Some channels such as contact list channels may not be closed.
References Telepathy::Client::AbstractInterface::invalidationMessage(), and Telepathy::Client::AbstractInterface::invalidationReason().
void Telepathy::Client::ChannelInterface::Closed | ( | ) | [signal] |
Represents the signal "Closed" on the remote object.
Emitted when the channel has been closed. Method calls on the channel are no longer valid after this signal has been emitted, and the connection manager may then remove the object from the bus at any point.
QDBusPendingReply<QString> Telepathy::Client::ChannelInterface::GetChannelType | ( | ) | [inline, slot] |
Begins a call to the D-Bus method "GetChannelType" on the remote object.
Returns the interface name for the type of this channel. Clients SHOULD use the ChannelType property instead, falling back to this method only if necessary. The GetAll method lets clients retrieve all properties in one round-trip.
References Telepathy::Client::AbstractInterface::invalidationMessage(), and Telepathy::Client::AbstractInterface::invalidationReason().
QDBusPendingReply<uint, uint> Telepathy::Client::ChannelInterface::GetHandle | ( | ) | [inline, slot] |
Begins a call to the D-Bus method "GetHandle" on the remote object.
Returns the handle type and number if this channel represents a communication with a particular contact, room or server-stored list, or zero if it is transient and defined only by its contents. Clients SHOULD use the TargetHandle and TargetHandleType properties instead, falling back to this method only if necessary. The GetAll method lets clients retrieve all properties in one round-trip.
References Telepathy::Client::AbstractInterface::invalidationMessage(), and Telepathy::Client::AbstractInterface::invalidationReason().
QDBusPendingReply<QStringList> Telepathy::Client::ChannelInterface::GetInterfaces | ( | ) | [inline, slot] |
Begins a call to the D-Bus method "GetInterfaces" on the remote object.
Get the optional interfaces implemented by the channel. Clients SHOULD use the Interfaces property instead, falling back to this method only if necessary. The GetAll method lets clients retrieve all properties in one round-trip.

Getter for the remote object property "TargetID".
Don't use this: it blocks the main loop.
QString Telepathy::Client::ChannelInterface::ChannelType [read] |
Represents property "ChannelType" on the remote object.
The channel's type. This cannot change once the channel has been created.
For compatibility between older connection managers and newer clients, if this is unavailable or is an empty string, clients MUST use the result of calling <tp:member-ref>GetChannelType</tp:member-ref>.
<tp:rationale> The GetAll method lets clients retrieve all properties in one round-trip, which is desirable. </tp:rationale>
When requesting a channel, the request MUST specify a channel type, and the request MUST fail if the specified channel type cannot be supplied.
<tp:rationale> Common sense. </tp:rationale>
uint Telepathy::Client::ChannelInterface::InitiatorHandle [read] |
Represents property "InitiatorHandle" on the remote object.
The contact who initiated the channel. For channels requested by the local user, this MUST be the value of <tp:dbus-ref namespace="org.freedesktop.Telepathy">Connection.SelfHandle</tp:dbus-ref> at the time the channel was created (i.e. not a channel-specific handle).
<tp:rationale>
The careful wording about the self-handle is because the Renaming interface can cause the return from Connection.GetSelfHandle to change. It's something of a specification bug that we don't signal this in the Connection interface yet. </tp:rationale>
For channels requested by a remote user, this MUST be their handle. If unavailable or not applicable, this MUST be 0 (for instance, contact lists are not really initiated by anyone in particular, and it's easy to imagine a protocol where chatroom invitations can be anonymous).
For channels with the <tp:dbus-ref namespace="org.freedesktop.Telepathy.Channel.Interface">Group</tp:dbus-ref> interface, this SHOULD be the same contact who is signalled as the "Actor" causing the self-handle to be placed in the local-pending set.
This SHOULD NOT be a channel-specific handle, if possible.
It does not make sense for this property to be in channel requests - the initiator will always be the local user - so it MUST NOT be accepted.
QString Telepathy::Client::ChannelInterface::InitiatorID [read] |
Represents property "InitiatorID" on the remote object.
The string that would result from inspecting the <tp:member-ref>InitiatorHandle</tp:member-ref> property (i.e. the initiator's identifier in the IM protocol).
<tp:rationale>
The presence of this property avoids the following race condition:
It does not make sense for this property to be in channel requests - the initiator will always be the local user - so it MUST NOT be accepted.
QStringList Telepathy::Client::ChannelInterface::Interfaces [read] |
Represents property "Interfaces" on the remote object.
Extra interfaces provided by this channel. This SHOULD NOT include the channel type and the Channel interface itself, and cannot change once the channel has been created.
For compatibility between older connection managers and newer clients, if this is unavailable, or if this is an empty list and <tp:member-ref>ChannelType</tp:member-ref> is an empty string, clients MUST use the result of calling <tp:member-ref>GetInterfaces</tp:member-ref> instead. If this is an empty list but ChannelType is non-empty, clients SHOULD NOT call GetInterfaces; this implies that connection managers that implement the ChannelType property MUST also implement the Interfaces property correctly.
<tp:rationale> The GetAll method lets clients retrieve all properties in one round-trip, which is desirable. </tp:rationale>
When requesting a channel with a particular value for this property, the request must fail without side-effects unless the connection manager expects to be able to provide a channel whose interfaces include at least the interfaces requested.
bool Telepathy::Client::ChannelInterface::Requested [read] |
Represents property "Requested" on the remote object.
True if this channel was created in response to a local request, such as a call to <tp:dbus-ref namespace="org.freedesktop.Telepathy">Connection.RequestChannel</tp:dbus-ref> or <tp:dbus-ref namespace="org.freedesktop.Telepathy">Connection.Interface.Requests.CreateChannel</tp:dbus-ref>.
<tp:rationale>
The idea of this property is to distinguish between "incoming" and "outgoing" channels, in a way that doesn't break down when considering special cases like contact lists that are automatically created on connection to the server, or chatrooms that an IRC proxy/bouncer like irssi-proxy or bip was already in.
The reason we want to make that distinction is that UIs for things that the user explicitly requested should start up automatically, whereas for incoming messages and VoIP calls we should first ask the user whether they want to open the messaging UI or accept the call. </tp:rationale>
If the channel was not explicitly requested (even if it was created as a side-effect of a call to one of those functions, e.g. because joining a Tube in a MUC context on XMPP implies joining that MUC), then this property is false.
For compatibility with older connection managers, clients SHOULD assume that this property is true if they see a channel announced by the <tp:dbus-ref namespace="org.freedesktop.Telepathy">Connection.NewChannel</tp:dbus-ref> signal with the suppress_handler parameter set to true.
<tp:rationale>
In a correct connection manager, the only way to get such a channel is to request it. </tp:rationale>
Clients MAY additionally assume that this property is false if they see a channel announced by the NewChannel signal with the suppress_handler parameter set to false.
<tp:rationale>
This is more controversial, since it's possible to get that parameter set to false by requesting a channel. However, there's no good reason to do so, and we've deprecated this practice.
In the particular case of the channel dispatcher, the only side-effect of wrongly thinking a channel is unrequested is likely to be that the user has to confirm that they want to use it, so it seems fairly harmless to assume in the channel dispatcher that channels with suppress_handler false are indeed unrequested. </tp:rationale>
It does not make sense for this property to be in channel requests—it will always be true for channels returned by CreateChannel, and callers of EnsureChannel cannot control whether an existing channel was originally requested locally—so it MUST NOT be accepted.
uint Telepathy::Client::ChannelInterface::TargetHandle [read] |
Represents property "TargetHandle" on the remote object.
The handle (a representation for the identifier) of the contact, chatroom, etc. with which this handle communicates. Its type is given by the <tp:member-ref>TargetHandleType</tp:member-ref> property.
This is fixed for the lifetime of the channel, so channels which could potentially be used to communicate with multiple contacts (such as streamed media calls defined by their members, or ad-hoc chatrooms like MSN switchboards) must have TargetHandleType set to Handle_Type_None and TargetHandle set to 0.
Unlike in the telepathy-spec 0.16 API, there is no particular uniqueness guarantee - there can be many channels with the same (channel type, handle type, handle) tuple. This is necessary to support conversation threads in XMPP and SIP, for example.
If this is present in a channel request, it must be nonzero, <tp:member-ref>TargetHandleType</tp:member-ref> MUST be present and not Handle_Type_None, and <tp:member-ref>TargetID</tp:member-ref> MUST NOT be present.
The channel that satisfies the request MUST either:
uint Telepathy::Client::ChannelInterface::TargetHandleType [read] |
Represents property "TargetHandleType" on the remote object.
The type of <tp:member-ref>TargetHandle</tp:member-ref>.
If this is omitted from a channel request, connection managers SHOULD treat this as equivalent to Handle_Type_None.
If this is omitted or is Handle_Type_None, <tp:member-ref>TargetHandle</tp:member-ref> and <tp:member-ref>TargetID</tp:member-ref> MUST be omitted from the request.
QString Telepathy::Client::ChannelInterface::TargetID [read] |
Represents property "TargetID" on the remote object.
The string that would result from inspecting the <tp:member-ref>TargetHandle</tp:member-ref> property (i.e. the identifier in the IM protocol of the contact, room, etc. with which this channel communicates), or the empty string if the TargetHandle is 0.
<tp:rationale>
The presence of this property avoids the following race condition:
If this is present in a channel request, <tp:member-ref>TargetHandleType</tp:member-ref> MUST be present and not Handle_Type_None, and <tp:member-ref>TargetHandle</tp:member-ref> MUST NOT be present. The request MUST fail with error InvalidHandle, without side-effects, if the requested TargetID would not be accepted by <tp:dbus-ref namespace="org.freedesktop.Telepathy.Connection">RequestHandles</tp:dbus-ref>.
The returned channel must be related to the handle corresponding to the given identifier, in the same way as if TargetHandle had been part of the request instead.
<tp:rationale>
Requesting channels with a string identifier saves a round-trip (the call to RequestHandles). It also allows the channel dispatcher to accept a channel request for an account that is not yet connected (and thus has no valid handles), bring the account online, and pass on the same parameters to the new connection's CreateChannel method. </tp:rationale>
