Constructor & Destructor Documentation

Tp::SimpleObserver::~SimpleObserver ( )
virtual

Class destructor.

Member Function Documentation

SimpleObserverPtr Tp::SimpleObserver::create ( const AccountPtr &  account,
const ChannelClassSpecList channelFilter,
const QList< ChannelClassFeatures > &  extraChannelFeatures = QList<ChannelClassFeatures>() 
)
static

Create a new SimpleObserver object.

Events will be signalled for all channels in account that match channelFilter for all contacts.

Parameters
channelFilterA specification of the channels in which this observer is interested.
accountThe account used to listen to events.
extraChannelFeaturesExtra channel features to be enabled. All channels emitted in newChannels() will have the extra features that match their immutable properties enabled.
Returns
An SimpleObserverPtr object pointing to the newly created SimpleObserver object.
SimpleObserverPtr Tp::SimpleObserver::create ( const AccountPtr &  account,
const ChannelClassSpecList channelFilter,
const ContactPtr &  contact,
const QList< ChannelClassFeatures > &  extraChannelFeatures = QList<ChannelClassFeatures>() 
)
static

Create a new SimpleObserver object.

Events will be signalled for all channels in account established with contact, if not null, and that match channelFilter.

Parameters
channelFilterA specification of the channels in which this observer is interested.
accountThe account used to listen to events.
contactThe contact used to filter events.
extraChannelFeaturesExtra channel features to be enabled. All channels emitted in newChannels() will have the extra features that match their immutable properties enabled.
Returns
An SimpleObserverPtr object pointing to the newly created SimpleObserver object.
SimpleObserverPtr Tp::SimpleObserver::create ( const AccountPtr &  account,
const ChannelClassSpecList channelFilter,
const QString &  contactIdentifier,
const QList< ChannelClassFeatures > &  extraChannelFeatures = QList<ChannelClassFeatures>() 
)
static

Create a new SimpleObserver object.

Events will be signalled for all channels in account established with a contact identified by contactIdentifier, if non-empty, and that match channelFilter.

Parameters
channelFilterA specification of the channels in which this observer is interested.
accountThe account used to listen to events.
contactIdentifierThe identifier of the contact used to filter events.
extraChannelFeaturesExtra channel features to be enabled. All channels emitted in newChannels() will have the extra features that match their immutable properties enabled.
Returns
An SimpleObserverPtr object pointing to the newly created SimpleObserver object.
AccountPtr Tp::SimpleObserver::account ( ) const

Return the account used to listen to events.

Returns
A pointer to the Account object.
ChannelClassSpecList Tp::SimpleObserver::channelFilter ( ) const

Return a specification of the channels that this observer is interested.

Returns
The specification of the channels as a list of ChannelClassSpec objects.
QString Tp::SimpleObserver::contactIdentifier ( ) const

Return the identifier of the contact used to filter events, or an empty string if none was provided at construction.

Returns
The identifier of the contact.
QList< ChannelClassFeatures > Tp::SimpleObserver::extraChannelFeatures ( ) const

Return the extra channel features to be enabled based on the channels immutable properties.

Returns
The features as a list of ChannelClassFeatures objects.
QList< ChannelPtr > Tp::SimpleObserver::channels ( ) const

Return the channels being observed.

Returns
A list of pointers to Channel objects.
void Tp::SimpleObserver::newChannels ( const QList< Tp::ChannelPtr > &  channels)
signal

Emitted whenever new channels that match this observer's criteria are created.

Parameters
channelsThe new channels.
void Tp::SimpleObserver::channelInvalidated ( const Tp::ChannelPtr &  channel,
const QString &  errorName,
const QString &  errorMessage 
)
signal

Emitted whenever a channel that is being observed is invalidated.

Parameters
channelThe channel that was invalidated.
errorNameA D-Bus error name (a string in a subset of ASCII, prefixed with a reversed domain name).
errorMessageA debugging message associated with the error.
