GDAL Vector Driver Open Options

Source: R/gdal_drivers.R
gdal_vector_driver_open_opts.Rd

Accessors for a driver's open options (the --oo / GDALOpenEx() channel), parsed from the driver's DMD_OPENOPTIONLIST metadata.

  • gdal_vector_driver_open_opts(): the open-option table for driver.

  • gdal_vector_driver_open_opts_defaults(): name to default (all, or one when opt_name given).

  • gdal_vector_driver_open_opts_values(): name to allowed values (only constrained options).

  • gdal_vector_driver_open_opts_types(): name to data_type.

Usage

gdal_vector_driver_open_opts(driver)

gdal_vector_driver_open_opts_defaults(driver, opt_name = NULL)

gdal_vector_driver_open_opts_values(driver, opt_name = NULL)

gdal_vector_driver_open_opts_types(driver)

Arguments

driver

Character scalar GDAL driver short name.

opt_name

Optional single option name. When supplied, returns the value for that option only; otherwise returns the full named result.

Value

A tibble::tibble(), named character vector, or named list (see gdal_vector_driver_opts()).
