signal datasetGroupsAdded[source]

pyqtSignal(*types, name: str = …, revision: int = …, arguments: Sequence = …) -> PYQT_SIGNAL

types is normally a sequence of individual types. Each type is either a type object or a string that is the name of a C++ type. Alternatively each type could itself be a sequence of types each describing a different overloaded signal. name is the optional C++ name of the signal. If it is not specified then the name of the class attribute that is bound to the signal is used. revision is the optional revision of the signal that is exported to QML. If it is not specified then 0 is used. arguments is the optional sequence of the names of the signal’s arguments.

driverMetadata(self) → QgsMeshDriverMetadata[source]

Returns the mesh driver metadata of the provider

Return type:

QgsMeshDriverMetadata

Returns:

the mesh driver metadata of the provider

Added in version 3.22.

setTemporalUnit(self, unit: Qgis.TemporalUnit)[source]

Sets the temporal unit of the provider and reload data if it changes.

Parameters:

unit (Qgis.TemporalUnit) – the temporal unit

Added in version 3.14.
