Detailed Description

Interface for mesh datasets.

Dataset is a collection of vector or scalar values on vertices or faces of the mesh. Based on the underlying data provider/format, whole dataset is either stored in memory or read on demand

Note

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

Since

QGIS 3.2

Member Function Documentation

addDataset()

virtual bool QgsMeshDatasetSourceInterface::addDataset ( const QString &  uri )

pure virtual

Associate dataset with the mesh.

datasetCount()

virtual int QgsMeshDatasetSourceInterface::datasetCount ( ) const

pure virtual

Returns number of datasets loaded.

datasetMetadata()

virtual QgsMeshDatasetMetadata QgsMeshDatasetSourceInterface::datasetMetadata ( int  datasetIndex ) const

pure virtual

Returns dataset metadata.

datasetValue()

virtual QgsMeshDatasetValue QgsMeshDatasetSourceInterface::datasetValue ( int  datasetIndex, int  valueIndex  ) const

pure virtual

Returns vector/scalar value associated with the index from the dataset.

See QgsMeshDatasetMetadata::isVector() to check if the returned value is vector or scalar
