qgis_explodehstorefield: QGIS algorithm - Explode HStore Field

In JanCaha/r_package_qgis: An extension of package "qgisprocess" providing direct R functions for QGIS functions

QGIS algorithm - Explode HStore Field

Description

QGIS Algorithm provided by QGIS (native c++) Explode HStore Field (native:explodehstorefield). This algorithm creates a copy of the input layer and adds a new field for every unique key in the HStore field. The expected field list is an optional comma separated list. By default, all unique keys are added. If this list is specified, only these fields are added and the HStore field is updated.

Usage

qgis_explodehstorefield(
  INPUT = qgisprocess:::qgis_default_value(),
  FIELD = qgisprocess:::qgis_default_value(),
  EXPECTED_FIELDS = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	source - Input layer. Path to a vector layer.
FIELD	field - HStore field. The name of an existing field. ; delimited list of existing field names.
EXPECTED_FIELDS	string - Expected list of fields separated by a comma. 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.
OUTPUT	sink - Exploded. 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.
