The vector layer constructor in turn instantiates a QgsMeshDataProvider subclass corresponding to the provider type, and passes it the url. The data provider connects to the data source. The QgsMeshLayer provides a common interface to the different data types. It does not yet support editing transactions. The main data providers supported by QGIS are listed below. \section mesh_providers Mesh data providers \subsection mesh_memory Memory data providerType (mesh_memory) The memory data provider is used to construct in memory data, for example scratch data. There is no inherent persistent storage of the data. The data source uri is constructed. Data can be populated by setMesh(const QString &vertices, const QString &faces), where vertices and faces is comma separated coordinates and connections for mesh. E.g. to create mesh with one quad and one triangle .. code-block:: QString uri( "1.0, 2.0 \n" \ "2.0, 2.0 \n" \ "3.0, 2.0 \n" \ "2.0, 3.0 \n" \ "1.0, 3.0 \n" \ "---" "0, 1, 3, 4 \n" \ "1, 2, 3 \n" ); QgsMeshLayer *scratchLayer = new QgsMeshLayer(uri, "My Scratch layer", "memory_mesh"); \subsection mdal MDAL data provider (mdal) Accesses data using the MDAL drivers (https://github.com/lutraconsulting/MDAL). The url is the MDAL connection string. QGIS must be built with MDAL support to allow this provider. .. code-block:: QString uri = "test/land.2dm"; QgsMeshLayer *scratchLayer = new QgsMeshLayer(uri, "My Scratch Layer", "mdal"); .. note:: The API is considered EXPERIMENTAL and can be changed without a notice .. versionadded:: 3.2 %End %TypeHeaderCode #include "qgsmeshlayer.h" %End public: struct LayerOptions { }; explicit QgsMeshLayer( const QString &path = QString(), const QString &baseName = QString(), const QString &providerLib = "mesh_memory", const QgsMeshLayer::LayerOptions &options = QgsMeshLayer::LayerOptions() ); %Docstring Constructor - creates a mesh layer The QgsMeshLayer is constructed by instantiating a data provider. The provider interprets the supplied path (url) of the data source to connect to and access the data. :param path: The path or url of the parameter.
