Usage

From source file:com.amazonaws.apigatewaydemo.RequestRouter.java

/**
 * The main Lambda function handler. Receives the request as an input stream, parses the json and looks for the
 * "action" property to decide where to route the request. The "body" property of the incoming request is passed
 * to the DemoAction implementation as a request body.
 *
 * @param request  The InputStream for the incoming event. This should contain an "action" and "body" properties. The
 *                 action property should contain the namespaced name of the class that should handle the invocation.
 *                 The class should implement the DemoAction interface. The body property should contain the full
 *                 request body for the action class.
 * @param response An OutputStream where the response returned by the action class is written
 * @param context  The Lambda Context object
 * @throws BadRequestException    This Exception is thrown whenever parameters are missing from the request or the action
 *                                class can't be found
 * @throws InternalErrorException This Exception is thrown when an internal error occurs, for example when the database
 *                                is not accessible
