[LSC] Add LOCAL_LICENSE_KINDS to external/geojson-jackson am: 6b8e3f0b0d Original change: https://googleplex-android-review.googlesource.com/c/platform/external/geojson-jackson/+/13741057 MUST ONLY BE SUBMITTED BY AUTOMERGER Change-Id: I6ae20c1863d0fc4ff2f0b27a47789867e7f4a1c9
A small package of all GeoJson POJOs (Plain Old Java Objects) for serializing and deserializing of objects via JSON Jackson Parser.
If you know what kind of object you expect from a GeoJson file you can directly read it like this:
FeatureCollection featureCollection = new ObjectMapper().readValue(inputStream, FeatureCollection.class);
If you want to read any GeoJson file read the value as GeoJsonObject and then test for the contents via instanceOf:
GeoJsonObject object = new ObjectMapper().readValue(inputStream, GeoJsonObject.class); if (object instanceof Polygon) { ... } else if (object instanceof Feature) { ... }
and so on.
Or you can use the GeoJsonObjectVisitor to visit the right method:
GeoJsonObject object = new ObjectMapper().readValue(inputStream, GeoJsonObject.class); object.accept(visitor);
Writing Json is even easier. You just have to create the GeoJson objects and pass them to the Jackson ObjectMapper.
FeatureCollection featureCollection = new FeatureCollection(); featureCollection.add(new Feature()); String json= new ObjectMapper().writeValueAsString(featureCollection);
You can find the library in the Maven Central Repository.
