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.

Parameters

name – name of the parameter
description – description of the parameter

Parameters

value (Any) –
context (QgsProcessingContext) –

Return type

str

valueAsTimeType(value: Any) → str¶

Returns the dataset value time type as a string : current-context-time : the time is store in the processing context (e.g. current canvas time), in this case the value does not contain any time value defined-date-time : absolute time of type QDateTime dataset-time-step : a time step of existing dataset, in this case the time takes the form of a QMeshDatasetIndex with value to the corresponding dataset index static : dataset groups are all static, in this case the value does not contain any time value

Parameters: value (Any) –
Return type: str
