QGIS algorithm - Build virtual vector — gdal

QGIS Algorithm provided by GDAL Build virtual vector (gdal:buildvirtualvector). This algorithm creates a virtual layer that contains a set of vector layers. The output virtual layer will not be opened in the current project.

gdal_buildvirtualvector(
  INPUT = qgisprocess:::qgis_default_value(),
  UNIONED = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT: multilayer - Input datasources. .
UNIONED: boolean - Create "unioned" VRT. 1 for true/yes. 0 for false/no. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
OUTPUT: vectorDestination - Virtual vector. Path for new vector layer.
...: further parameters passed to qgisprocess::qgis_run_algorithm()
.complete_output: 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.
.quiet: logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.
.messages: logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
