Using 64 bit integers in custom data with HERE OLP Data Visulization Library

When using a protobuf schema that contains messages with fields of types like int64/sint64 and trying to visualize that with a custom renderer plugin, the decoded data that is passed to the renderer plugin contains fields with type number instead of Long from https://github.com/dcodeIO/Long.js/. I've been able to fix this in my local webapp by patching GeoJsonDataStoreHelper.js with

var Protobuf = require("protobufjs");
var Long = require("long");
Protobuf.util.Long = Long;
Protobuf.configure();

Is there anything I can do to fix this without changing the code of the visualization library? Otherwise rendering on OLP won't work.

Solution

  • at this moment you could fix that only temporarily like you did it by modification of geojson-datasource code directly. We are working on the proper support of int64 in our geojson package.
