Detailed Description

QgsMeshDatasetGroupMetadata is a collection of dataset group metadata such as whether the data is vector or scalar, name.

Note: The API is considered EXPERIMENTAL and can be changed without a notice

Since: QGIS 3.4

Member Enumeration Documentation

◆ DataType

enum QgsMeshDatasetGroupMetadata::DataType

Location of where data is specified for datasets in the dataset group.

Enumerator
DataOnFaces	Data is defined on faces.
DataOnVertices	Data is defined on vertices.

Definition at line 245 of file qgsmeshdataprovider.h.

Constructor & Destructor Documentation

◆ QgsMeshDatasetGroupMetadata() [1/2]

QgsMeshDatasetGroupMetadata::QgsMeshDatasetGroupMetadata ( )

default

Constructs an empty metadata object.

◆ QgsMeshDatasetGroupMetadata() [2/2]

QgsMeshDatasetGroupMetadata::QgsMeshDatasetGroupMetadata	(	const QString &	name,
		bool	isScalar,
		bool	isOnVertices,
		double	minimum,
		double	maximum,
		const QMap< QString, QString > &	extraOptions
	)

Constructs a valid metadata object.

Parameters

name	name of the dataset group
isScalar	dataset contains scalar data, specifically the y-value of QgsMeshDatasetValue is NaN
isOnVertices	dataset values are defined on mesh's vertices. If `false`, values are defined on faces.
minimum	minimum value (magnitude for vectors) present among all group's dataset values
maximum	maximum value (magnitude for vectors) present among all group's dataset values
extraOptions	dataset's extra options stored by the provider. Usually contains the name, time value, time units, data file vendor, ...
