fr.mines_stetienne.ci.sparql_generate.iterator.IteratorFunction

public class ITER_GeoJSON
extends fr.mines_stetienne.ci.sparql_generate.iterator.IteratorFunctionBase1

Iterator function iter:GeoJSON iterates over the features collection of a GeoJSON document, and outputs (1) the Geometry as a wktLiteral, and (2) the Features as a JSON Literal

See Live example

• Param 1: (geojson): the URI of the GeoJSON document (a URI), or the GeoJSON object itself (a String);

The following variables may be bound:

• Output 1: (wktLiteral) geometry of the feature;
• Output 2: (json literal) properties of the feature
