Member Function Documentation

◆ appendMapParameter()

QString QgsServerApiUtils::appendMapParameter	(	const QString &	path,

	)

static

Appends MAP query string parameter from current requestUrl to the given path.

Definition at line 617 of file qgsserverapiutils.cpp.

◆ crsToOgcUri()

QString QgsServerApiUtils::crsToOgcUri ( const QgsCoordinateReferenceSystem & crs )

static

Returns a crs as OGC URI (format: http://www.opengis.net/def/crs/OGC/1.3/CRS84) Returns an empty string on failure.

Definition at line 594 of file qgsserverapiutils.cpp.

◆ layerExtent()

json QgsServerApiUtils::layerExtent ( const QgsVectorLayer * layer )

static

layerExtent returns json array with [xMin,yMin,xMax,yMax] CRS84 extent for the given layer

Definition at line 438 of file qgsserverapiutils.cpp.

◆ parseBbox()

QgsRectangle QgsServerApiUtils::parseBbox ( const QString & bbox )

static

Parses a comma separated bbox into a (possibly empty) QgsRectangle.

Note: Z values (i.e. a 6 elements bbox) are silently discarded

Definition at line 32 of file qgsserverapiutils.cpp.

◆ parseCrs()

QgsCoordinateReferenceSystem QgsServerApiUtils::parseCrs ( const QString & bboxCrs )

static

Parses the CRS URI bboxCrs (example: "http://www.opengis.net/def/crs/OGC/1.3/CRS84") into a QGIS CRS object.

Definition at line 546 of file qgsserverapiutils.cpp.

◆ parseTemporalDateInterval()

QgsDateRange QgsServerApiUtils::parseTemporalDateInterval ( const QString & interval )

static

Parses a date interval and returns a QgsDateRange.

Exceptions

QgsServerApiBadRequestException if interval cannot be parsed

Since: QGIS 3.12

Definition at line 130 of file qgsserverapiutils.cpp.

◆ parseTemporalDateTimeInterval()

QgsDateTimeRange QgsServerApiUtils::parseTemporalDateTimeInterval ( const QString & interval )

static

Parses a datetime interval and returns a QgsDateTimeRange.

Exceptions

QgsServerApiBadRequestException if interval cannot be parsed

Since: QGIS 3.12

Definition at line 135 of file qgsserverapiutils.cpp.

◆ publishedCrsList()

QStringList QgsServerApiUtils::publishedCrsList ( const QgsProject * project )

static

Returns the list of CRSs (format: http://www.opengis.net/def/crs/OGC/1.3/CRS84) available for this project.

Information is read from project WMS configuration.

Definition at line 575 of file qgsserverapiutils.cpp.

◆ publishedWfsLayers() [1/2]

const QVector< QgsVectorLayer * > QgsServerApiUtils::publishedWfsLayers ( const QgsServerApiContext & context )

static

Returns the list of layers accessible to the service for a given context.

This method takes into account the ACL restrictions provided by QGIS Server Access Control plugins.

Definition at line 564 of file qgsserverapiutils.cpp.

◆ publishedWfsLayers() [2/2]

template<typename T >

static const QVector<T> QgsServerApiUtils::publishedWfsLayers ( const QgsServerApiContext & context )

inlinestatic

Returns the list of layers of type T accessible to the WFS service for a given project.

Example:

QVector<const QgsVectorLayer*> vectorLayers = publishedLayers<QgsVectorLayer>();

Note: not available in Python bindings

Definition at line 173 of file qgsserverapiutils.h.

◆ sanitizedFieldValue()

QString QgsServerApiUtils::sanitizedFieldValue ( const QString & value )

static

Sanitizes the input value by removing URL encoding.

Note: the returned value is meant to become part of a QgsExpression filter

Definition at line 569 of file qgsserverapiutils.cpp.

◆ temporalDimensions()

QList< QgsVectorLayerServerProperties::WmsDimensionInfo > QgsServerApiUtils::temporalDimensions ( const QgsVectorLayer * layer )

static

Returns a list of temporal dimensions information for the given layer (either configured in wmsDimensions or the first date/datetime field)

Since: QGIS 3.12

Definition at line 65 of file qgsserverapiutils.cpp.

◆ temporalExtent()

json QgsServerApiUtils::temporalExtent ( const QgsVectorLayer * layer )

static

temporalExtent returns a json array with an array of [min, max] temporal extent for the given layer.

In case multiple temporal dimensions are available in the layer, a union of all dimensions is returned.

From specifications: http://schemas.opengis.net/ogcapi/features/part1/1.0/openapi/schemas/extent.yaml

One or more time intervals that describe the temporal extent of the dataset. The value null is supported and indicates an open time interval.

In the Core only a single time interval is supported. Extensions may support multiple intervals. If multiple intervals are provided, the union of the intervals describes the temporal extent.

Returns: An array of intervals

Note: not available in Python bindings

Since: QGIS 3.12

Definition at line 450 of file qgsserverapiutils.cpp.

◆ temporalExtentList()

QVariantList QgsServerApiUtils::temporalExtentList ( const QgsVectorLayer * layer )

static

temporalExtent returns a json array with an array of [min, max] temporal extent for the given layer.

In case multiple temporal dimensions are available in the layer, a union of all dimensions is returned.

From specifications: http://schemas.opengis.net/ogcapi/features/part1/1.0/openapi/schemas/extent.yaml

One or more time intervals that describe the temporal extent of the dataset. The value null is supported and indicates an open time interval.

In the Core only a single time interval is supported. Extensions may support multiple intervals. If multiple intervals are provided, the union of the intervals describes the temporal extent.

Returns: An array of intervals

Since: QGIS 3.12

Definition at line 539 of file qgsserverapiutils.cpp.

◆ temporalFilterExpression()

QgsExpression QgsServerApiUtils::temporalFilterExpression	(	const QgsVectorLayer *	layer,
		const QString &	interval
	)

static

Parses the interval and constructs a (possibly invalid) temporal filter expression for the given layer.

Interval syntax:

interval-closed = date-time "/" date-time interval-open-start = [".."] "/" date-time interval-open-end = date-time "/" [".."] interval = interval-closed / interval-open-start / interval-open-end datetime = date-time / interval
