QGIS Algorithm provided by QGIS (native c++) Holes (native:checkgeometryhole). Detects holes inside polygons. This algorithm checks the holes of polygon geometries. Holes are errors.

  INPUT = qgisprocess:::qgis_default_value(),
  UNIQUE_ID = qgisprocess:::qgis_default_value(),
  ERRORS = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),

)

Arguments

INPUT

source - Input layer. Path to a vector layer.

UNIQUE_ID

field - Unique feature identifier. The name of an existing field. ; delimited list of existing field names.

ERRORS

sink - Holes errors. Path for new vector layer.

OUTPUT

sink - Polygons with holes. Path for new vector layer.

TOLERANCE

number - Tolerance. A numeric 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.

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.
