  • Field Details

    • NO_SPEED_LIMIT

      public static final double NO_SPEED_LIMIT
      Sentinel speed (km/h) used when no speed limit is known. It is high enough not to constrain real railway traffic, while avoiding infinity in downstream maths.

    • getStreamFromResourceString

      public static InputStream getStreamFromResourceString(String resource) throws IOException
      Retrieves an InputStream from a resource string, which can either be a URI or a classpath resource. If the resource string represents a valid URI, the input stream is opened from the URI. Otherwise, the input stream is retrieved from the classpath using the resource string.
      Parameters:
      resource - the resource string, which can be a URI or a classpath resource
      Returns:
      the InputStream corresponding to the resource
      Throws:
      IOException - if the resource cannot be found or accessed
