Constructs a conversation message from a map of arguments.

ConversationMessage::ConversationMessage(const qint32 &eventField,
                                         const QString &body,
                                         const QList &addresses,
                                         const qint64 &date,
                                         const qint32 &type,
                                         const qint32 &read,
                                         const qint64 &threadID,
                                         const qint32 &uID,
                                         const qint64 &subID,
                                         const QList &attachments)
    : m_eventField(eventField)
    , m_body(body)
    , m_addresses(addresses)
    , m_date(date)
    , m_type(type)
    , m_read(read)
    , m_threadID(threadID)
    , m_uID(uID)
    , m_subID(subID)
    , m_attachments(attachments)
{
}

Constructs a conversation message object.

ConversationMessage ConversationMessage::fromDBus(const QDBusVariant &var)
{
    QDBusArgument data = var.variant().value();
    ConversationMessage message;
    data >> message;
    return message;
}

This creates a conversation message from a dbus variant.

ConversationAddress::ConversationAddress(QString address)
    : m_address(address)
{
}

Constructs a conversation address object from an address string.

bool ConversationMessage::isOutgoing() const
{
    return type() == MessageTypeSent || type() == MessageTypeOutbox || type() == MessageTypeDraft || type() == MessageTypeFailed || type() == MessageTypeQueued;
}

This implements checking if the message type is outgoing.

Attachment::Attachment(qint64 partID, QString mimeType, QString base64EncodedFile, QString uniqueIdentifier)
    : m_partID(partID)
    , m_mimeType(mimeType)
    , m_base64EncodedFile(base64EncodedFile)
    , m_uniqueIdentifier(uniqueIdentifier)
{
}

Constructs an attachment object of the given part id, mimeType base64 encoded file and unique identifier.

void ConversationMessage::registerDbusType()
{
    qDBusRegisterMetaType();
    qRegisterMetaType();
    qDBusRegisterMetaType();
    qRegisterMetaType();
    qDBusRegisterMetaType>();
    qRegisterMetaType>();
    qDBusRegisterMetaType();
    qRegisterMetaType();
}

This registers the meta types for a conversation message. It allows to register multiple addresses for a conversation.
