Detailed Description

Deletes a feed on the News App server.

To delete a feed on the server, set DeleteFeed::feedId to a valid ID and set an AbstractConfiguration to Component::configuration.

If a valid AbstractStorage object is set to the Component::storage property, AbstractStorage::feedDeleted() will be called in the successCallback() to delete the feed in the local storage. If the request succeeded, the succeed() signal will be emitted in the successCallback() and it will contain the id of the deleted feed. If the request failed, Component::faild() will be emitted and Component::error contains a valid pointer to an Error object.

Mandatory properties

DeleteFeed::feedId, Component::configuration

API route

/feeds/{feedId}

Method

DELETE

Property Documentation

feedId

qint64 Fuoten::DeleteFeed::feedId

readwrite

ID of the feed to delete.

This property can not be changed while Component::inOperation() returns true.

Access functions:

qint64	feedId() const
void	setFeedId(qint64 nFeedId)

Notifier signal:

void	feedIdChanged(qint64 feedId)

Constructor & Destructor Documentation

DeleteFeed()

DeleteFeed::DeleteFeed ( QObject * parent = nullptr )

explicit

Constructs an API request object with the given parent to delete a feed on the remote server.

~DeleteFeed()

DeleteFeed::~DeleteFeed ( )

override

Destroys the DeleteFeed object.

Member Function Documentation

checkInput()

bool DeleteFeed::checkInput ( )

overrideprotectedvirtual

Checks for a valid feed ID.

This will at first perform the checks of Component::checkInput() and will than simply check if the feed id is greater than zero.

Reimplemented from Fuoten::Component.

execute()

void DeleteFeed::execute ( )

overridevirtual

Executes the API request.

To perform a successful API request to delete a feed, DeleteFeed::feedId has to be a valid feed ID and there has to be an AbstractConfiguration object set to Component::configuration.

Execution will not run while Component::inOperation returns true and will itself set that property to true when the request starts.

Implements Fuoten::Component.

extractError()

void DeleteFeed::extractError ( QNetworkReply * reply )

overrideprotectedvirtual

Extracts possible errors replied by the News App API.

Reimplemented from Fuoten::Component.

feedId()

qint64 DeleteFeed::feedId

(

)

const

Returns the ID of the feed to delete.

See also

feedId

feedIdChanged

void Fuoten::DeleteFeed::feedIdChanged ( qint64 feedId )

signal

This is emitted if the ID of the feed to delete changes.

See also

feedId

setFeedId()

void DeleteFeed::setFeedId

(

qint64

nFeedId

)

Sets the ID of the feed to delete.

See also

feedId

succeeded

void Fuoten::DeleteFeed::succeeded ( qint64 id )

signal

Will be emitted in the success callback function and contains the ID of the deleted folder.

See also

Component::failed()

successCallback()

void DeleteFeed::successCallback ( )

overrideprotectedvirtual

Finishes the feed deletion if the request was successful.

Implements Fuoten::Component.
