Member Enumeration Documentation

enum QgsAuthMethod::Expansion

Flags that represent the update points (where authentication configurations are expanded) supported by an authentication method.

These equate to the 'update*()' virtual functions below, and allow for update point code to skip calling an unused update by a method, because the base virtual function will always return true, giving a false impression an update occurred.

Note: When adding an 'update' member function, also add the corresponding Expansion flag.; These flags will be added to as new update points are added

Constructor & Destructor Documentation

QgsAuthMethod::QgsAuthMethod ( )

inlineexplicitprotected

Construct a default authentication method.

Note: Non-public since this is an abstract base class

Definition at line 175 of file qgsauthmethod.h.

Member Function Documentation

static QString QgsAuthMethod::authMethodTag ( )

inlinestaticprotected

Tag signifying that this is an authentcation method (e.g. for use as title in message log panel output)

Definition at line 183 of file qgsauthmethod.h.

virtual void QgsAuthMethod::clearCachedConfig ( const QString & authcfg )

pure virtual

Clear any cached configuration.

Called when the QgsAuthManager deletes an authentication configuration (authcfg).

Note: It is highly recommended that a cache of authentication components (per requested authcfg) be implemented, to avoid excessive queries on the auth database. Such a cache could be as simple as a QHash or QMap of authcfg -> QgsAuthMethodConfig. See 'Basic' auth method plugin for example.

virtual QString QgsAuthMethod::description ( ) const

pure virtual

A non-translated short description representing the auth method for use in debug output and About dialog.

virtual QString QgsAuthMethod::displayDescription ( ) const

pure virtual

Translatable display version of the 'description()'.

virtual QString QgsAuthMethod::key ( ) const

pure virtual

A non-translated short name representing the auth method.

void QgsAuthMethod::setDataProviders ( const QStringList & dataproviders )

inlineprotected

Sets list of data providers this auth method supports.

Definition at line 191 of file qgsauthmethod.h.

void QgsAuthMethod::setExpansions ( QgsAuthMethod::Expansions expansions )

inlineprotected

Sets the support expansions (points in providers where the authentication is injected) of the auth method.

Definition at line 189 of file qgsauthmethod.h.

void QgsAuthMethod::setVersion ( int version )

inlineprotected

Sets the version of the auth method (useful for future upgrading)

Definition at line 186 of file qgsauthmethod.h.

QStringList QgsAuthMethod::supportedDataProviders ( ) const

inline

The data providers that the method supports, allowing for filtering out authcfgs that are not applicable to a given provider, or where the updating code is not currently implemented.

Definition at line 85 of file qgsauthmethod.h.

QgsAuthMethod::Expansions QgsAuthMethod::supportedExpansions ( ) const

inline

Flags that represent the update points (where authentication configurations are expanded) supported by an authentication method.

Note: These should directly correlate to existing 'update*()' member functions

Definition at line 79 of file qgsauthmethod.h.

virtual bool QgsAuthMethod::updateDataSourceUriItems	(	QStringList &	connectionItems,
		const QString &	authcfg,
		const QString &	dataprovider = `QString()`
	)

inlinevirtual

Update data source connection items with authentication components.

Parameters

connectionItems	QStringlist of 'key=value' pairs, as utilized in QgsDataSourceUri::connectionInfo()
authcfg	Authentication configuration ID
dataprovider	Textual key for a data provider, e.g. 'postgres', that allows for custom updater code specific to the provider

Returns: Whether the update succeeded

Definition at line 129 of file qgsauthmethod.h.

virtual void QgsAuthMethod::updateMethodConfig ( QgsAuthMethodConfig & mconfig )

pure virtual

Update an authentication configuration in place.

Note: Useful for updating previously stored authcfgs, when an authentication method has been significantly updated

virtual bool QgsAuthMethod::updateNetworkProxy	(	QNetworkProxy &	proxy,
		const QString &	authcfg,
		const QString &	dataprovider = `QString()`
	)

inlinevirtual

Update proxy settings with authentication components.

Parameters

proxy
authcfg	Authentication configuration ID
dataprovider	Textual key for a data provider, e.g. 'proxy', that allows for custom updater code specific to the provider

Returns: Whether the update succeeded

Definition at line 146 of file qgsauthmethod.h.

virtual bool QgsAuthMethod::updateNetworkReply	(	QNetworkReply *	reply,
		const QString &	authcfg,
		const QString &	dataprovider = `QString()`
	)

inlinevirtual

Update a network reply with authentication components.

Parameters

reply	The network reply object to update
authcfg	Authentication configuration ID
dataprovider	Textual key for a data provider, e.g. 'postgres', that allows for custom updater code specific to the provider

Returns: Whether the update succeeded

Definition at line 112 of file qgsauthmethod.h.

virtual bool QgsAuthMethod::updateNetworkRequest	(	QNetworkRequest &	request,
		const QString &	authcfg,
		const QString &	dataprovider = `QString()`
	)

inlinevirtual

Update a network request with authentication components.

Parameters

request	The network request to update
authcfg	Authentication configuration ID
dataprovider	Textual key for a data provider, e.g. 'postgres', that allows for custom updater code specific to the provider

Returns: Whether the update succeeded

Definition at line 95 of file qgsauthmethod.h.

int QgsAuthMethod::version ( ) const

inline

Increment this if method is significantly updated, allow updater code to be written for previously stored authcfg.

Definition at line 72 of file qgsauthmethod.h.
