Member Function Documentation

basicJson()

static QJsonObject Quotient::Event::basicJson ( const QString &  matrixType, const QJsonObject &  content  )

inlinestatic

Make a minimal correct Matrix event JSON.

Definition at line 245 of file event.h.

contentJson()

const QJsonObject Quotient::Event::contentJson

(

)

const

contentPart()

template<typename T , typename KeyT >

const T Quotient::Event::contentPart ( KeyT &&  key ) const

inline

Get a part of the content object, assuming a given type.

This retrieves the value under content.<key> from the event JSON and then converts it to T using fromJson().

switchOnType()

template<typename... VisitorTs>

auto Quotient::Event::switchOnType ( VisitorTs &&...  visitors ) const

inline

Apply one of the visitors based on the actual event type.

This function uses function_traits template and is() to find the first of the passed visitor invocables that can be called with this event object, downcasting *this in a type-safe way to the most specific type accepted by the visitor. Without this function, you can still write a stack of, for example, (else) if (const auto* evtPtr = eventCast<...>(baseEvtPtr)) blocks but switchType() provides a more concise and isolating syntax: there's no else or trailing return/break to forget, for one. The visitors have to all return the same type (possibly void). Here's how you might use this function:

RoomEventPtr eptr = /* get the event pointer from somewhere */;
const auto result = eptr->switchOnType(
    [](const RoomMemberEvent& memberEvent) {
        // Do what's needed if eptr points to a RoomMemberEvent
        return 1;
    },
    [](const CallEvent& callEvent) {
        // Do what's needed if eptr points to a CallEvent or any
        // class derived from it
        return 2;
    },
    3); /* the default value to return if nothing above matched */

As the example shows, the last parameter can optionally be a plain returned value instead of a visitor.

unsignedJson()

unsignedPart()

template<typename T , typename KeyT >

const T Quotient::Event::unsignedPart ( KeyT &&  key ) const

inline

Get a part of the unsigned object, assuming a given type.

This retrieves the value under unsigned.<key> from the event JSON and then converts it to T using fromJson().
