Method Detail

extractArguments

public static Map<String,Object> extractArguments(RouteContext routeContext,
                                  Map<String,Consumer> consumers)

Extracts the arguments from the current request for the target route.

Parameters:

routeContext - the RouteContext.

Returns:

Object[] an array of Object matching the route targets parameters.

extractBody

private static Object extractBody(RouteContext routeContext,
                 Parameter<?> parameter,
                 Map<String,Consumer> consumers)

extractPathParam

public static com.google.common.base.Optional<String> extractPathParam(RouteContext routeContext)

Extracts a path parameter from the passed in request path.

Parameters:

routeContext - the RouteContext to extract a path parameter from.

Returns:

Optional<String> containing the extracted path param if present in the request path.

extractIogiParam

public static com.google.common.base.Optional<?> extractIogiParam(RouteContext routeContext)

Returns an instance of the type used in the parameter names using Iogi.

For example, having form parameters named 'car.color', 'car.brand', this method would try to use those values to instantiate a new Car instance.

Returns:

Optional may contain the instantiated instance, else isPresent will return false.

addIfPresent

private static boolean addIfPresent(com.google.common.base.Optional<?> op,
                   String paramName,
                   Map<String,Object> args)

extractHeaderParam

private static com.google.common.base.Optional<?> extractHeaderParam(RouteContext routeContext,
                                                    RequestParameter<?> parameter)

extractCookieParam

private static com.google.common.base.Optional<?> extractCookieParam(RouteContext routeContext,
                                                    RequestParameter<?> parameter)

extractParam

private static com.google.common.base.Optional<?> extractParam(RouteContext routeContext,
                                              RequestParameter<?> parameter)
