NS API

An API for talking to the NS (Dutch railways) API interface written in Java. The NS is using a mix between Dutch and English terms in their API. This reflects back to the Java implementation. The preferred language is English but some Dutch terms show up. Javadoc is English. When Dutch terms are used a translation is provided

Usage

To use the NS api you need to register an account with the NS. You can apply for an account at NS API.

You will receive a username and password. To use the Java api, you initialize the NsApi object:

NsApi nsApi = new NsApi(username, password);

Next step is to create a request, eg a 'actuele vertrektijden' request to get the current departures:

ApiRequest<ActueleVertrekTijden> request = RequestBuilder.getActueleVertrektijden(stationName)

To do the actual request, you call getApiResponse with your request:

ActueleVertrekTijden vertrekTijden = nsApi.getApiResponse(request); 

A new immutable object ActueleVertrekTijden is created containing the result of the API call.

All classes are immutable and thread safe.
