QGIS algorithm - Save vector features to file

Description

QGIS Algorithm provided by QGIS (native c++) Save vector features to file (native:savefeatures). This algorithm saves vector features to a specified file dataset. For dataset formats supporting layers, an optional layer name parameter can be used to specify a custom string. Optional GDAL-defined dataset and layer options can be specified. For more information on this, read the online GDAL documentation.

Usage

qgis_savefeatures(
  INPUT = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  LAYER_NAME = qgisprocess:::qgis_default_value(),
  DATASOURCE_OPTIONS = qgisprocess:::qgis_default_value(),
  LAYER_OPTIONS = qgisprocess:::qgis_default_value(),
  ACTION_ON_EXISTING_FILE = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT

source - Vector features. Path to a vector layer.

OUTPUT

fileDestination - Saved features. Path for new file.

LAYER_NAME

string - Layer name. String value. 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.

DATASOURCE_OPTIONS

string - GDAL dataset options (separate individual options with semicolons). String value. 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.

LAYER_OPTIONS

string - GDAL layer options (separate individual options with semicolons). String value. 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.

ACTION_ON_EXISTING_FILE

enum of ⁠("Create or overwrite file", "Create or overwrite layer", "Append features to existing layer, but do not create new fields", "Append features to existing layer, and create new fields if needed")⁠ - Action to take on pre-existing file. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

...

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.
