Class: QgsProcessingParameterMeshDatasetTime

class qgis.core.QgsProcessingParameterMeshDatasetTime

Bases: QgsProcessingParameterDefinition

A parameter for processing algorithms that need a list of mesh dataset index from time parameter.

A valid value for this parameter is a map (QVariantMap) with in this form:

• “type” : the type of time settings “current-context-time”, “defined-date-time”, “dataset-time-step” or “none” if all the dataset groups are static

• “value” : nothing if type is “static” or “current-context-time”, QDateTime if “defined-date-time” or, for “dataset_time_step”, list of two int representing the dataset index that is the reference for the time step

Note

This parameter is dependent on a mesh layer parameter (QgsProcessingParameterMeshLayer) and on mesh datast group parameter (QgsProcessingParameterMeshDatasetGroups)

New in version 3.18.

• name – name of the parameter

• description – description of the parameter
