Member Enumeration Documentation

◆ 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
namename of the dataset group
isScalardataset contains scalar data, specifically the y-value of QgsMeshDatasetValue is NaN
isOnVerticesdataset values are defined on mesh's vertices. If false, values are defined on faces.
minimumminimum value (magnitude for vectors) present among all group's dataset values
maximummaximum value (magnitude for vectors) present among all group's dataset values
extraOptionsdataset's extra options stored by the provider. Usually contains the name, time value, time units, data file vendor, ...
