QGIS Algorithm provided by QGIS (native c++) Collect geometries (native:collect). This algorithm takes a vector layer and collects its geometries into new multipart geometries. One or more attributes can be specified to collect only geometries belonging to the same class (having the same value for the specified attributes), alternatively all geometries can be collected. All output geometries will be converted to multi geometries, even those with just a single part. This algorithm does not dissolve overlapping geometries - they will be collected together without modifying the shape of each geometry part. See the 'Promote to multipart' or 'Aggregate' algorithms for alternative options.

)source - Input layer. Path to a vector layer.
field - Unique ID fields. The name of an existing field. ; delimited list of existing field names.
sink - Collected. Path for new vector layer.
further parameters passed to qgisprocess::qgis_run_algorithm()
logical specifying if complete out of qgisprocess::qgis_run_algorithm() should be used (TRUE) or first output (most likely the main) should read (FALSE). Default value is TRUE.
logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.
logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
