Unable to overwrite isGeometryValid function. #50
Description
Running this in NodeJS, I seem to be unable to overwrite this function to provide a custom implementation (as suggested by the comment). Here is a snippet of what I'm trying to do:
function translate(json) {
GeoJSON.isGeometryValid = GJV.isGeometryObject;
return GeoJSON.parse(json, { Point: 'coords', doThrows: { invalidGeometry: true } } );
}This appears to be a scoping issue. You can set the function on the GeoJSON object, but that does not change the function used internally. I've tested this with a few console.log statements. For example:
function translate(json) {
GeoJSON.isGeometryValid = GJV.isGeometryObject;
console.log(GeoJSON.isGeometryValid); // displays the GJV.isGeometryObject function
return GeoJSON.parse(json, { Point: 'coords', doThrows: { invalidGeometry: true } } );
}In geojson.js:
...
GeoJSON.parse = function(objects, params, callback) {
...
console.log(GeoJSON.isGeometryValid); // displays the original GeoJSON.isGeometryValid function
geomAttrs.length = 0;
...
}Maybe the isGeometryValid function should be included in the GeoJSON.defaults object, allowing for it to be overwritten as part of the params parameter?
