Constructor & Destructor Documentation

◆ QgsConfigCache() [1/2]

QgsConfigCache::QgsConfigCache ( QgsServerSettings settings)

Initialize from settings.

Definition at line 81 of file qgsconfigcache.cpp.

◆ QgsConfigCache() [2/2]

QgsConfigCache::QgsConfigCache ( QgsAbstractCacheStrategy strategy)

Initialize with a strategy implementation.

Definition at line 87 of file qgsconfigcache.cpp.

Member Function Documentation

◆ initialize()

void QgsConfigCache::initialize ( QgsServerSettings settings)
static

Initialize from settings.

This method must be called prior any call to QgsConfigCache::instance

Definition at line 58 of file qgsconfigcache.cpp.

◆ instance()

QgsConfigCache * QgsConfigCache::instance ( )
static

Returns the current instance.

Definition at line 71 of file qgsconfigcache.cpp.

◆ project()

const QgsProject * QgsConfigCache::project ( const QString &  path,
const QgsServerSettings settings = nullptr 
)

If the project is not cached yet, then the project is read from the path.

If the project is not available, then nullptr is returned. If the project contains any bad layer it is considered unavailable unless the server configuration variable QGIS_SERVER_IGNORE_BAD_LAYERS passed in the optional settings argument is set to true (the default value is false).

Parameters
paththe filename of the QGIS project
settingsQGIS server settings
Returns
the project or nullptr if an error happened

Definition at line 98 of file qgsconfigcache.cpp.

◆ projectRemovedFromCache

void QgsConfigCache::projectRemovedFromCache ( const QString &  path)
signal

Emitted whenever a project is removed from the cache.

Since
QGIS 3.38

◆ projects()

QList< QgsProject * > QgsConfigCache::projects ( ) const

Returns projects currently in cache.
