Member Function Documentation

◆ applyAccessControlLayerFilters() [1/2]

static void QgsOWSServerFilterRestorer::applyAccessControlLayerFilters	(	const QgsAccessControl *	accessControl,
		QgsMapLayer *	mapLayer,
		QHash< QgsMapLayer *, QString > &	originalLayerFilters
	)

static

Apply filter from AccessControl.

◆ applyAccessControlLayerFilters() [2/2]

static void QgsOWSServerFilterRestorer::applyAccessControlLayerFilters	(	const QgsAccessControl *	accessControl,
		QgsMapLayer *	mapLayer
	)

static

Applies filters from access control on layer.

Parameters

accessControl	The access control instance
mapLayer	The layer on which the filter has to be applied

Since: QGIS 3.0

◆ operator=()

QgsOWSServerFilterRestorer& QgsOWSServerFilterRestorer::operator= ( const QgsOWSServerFilterRestorer & rh )

delete

QgsOWSServerFilterRestorer cannot be copied.

◆ originalFilters()

QHash<QgsMapLayer *, QString>& QgsOWSServerFilterRestorer::originalFilters ( )

inline

Returns a reference to the object's hash of layers to original subsetString filters.

Original layer subsetString filters MUST be inserted into this hash before modifying them.

Definition at line 62 of file qgsfilterrestorer.h.

◆ restoreLayerFilters()

void QgsOWSServerFilterRestorer::restoreLayerFilters ( const QHash< QgsMapLayer *, QString > & filterMap )

Apply filter from AccessControal.

Restore layer filter as original
