Method Detail

• deserializeParameter

  public static <T> T deserializeParameter(Class<T> parameterType,
                                           String parameter,
                                           String targetClass)

  Deserializer method for known parameter types.

  Type Parameters:

  T - the type to deserialize into

  Parameters:

  parameterType - class to deserialize parameter as

  parameter - parameter to deserialize

  targetClass - name of handled class for exception usage

  Returns:

  converted parameter as class if parameterType of supported type

• deserializeRouteParameters

  public static Object deserializeRouteParameters(Class<?> navigationTarget,
                                                  List<String> parameters)

  Deserializes the list of url segments to an instance of the parameter type. Attempts to cast the first parameter segment to the parameter type and returns null if the parameter list is empty.

  Parameters:

  navigationTarget - navigation target for which to deserialize parameters

  parameters - the list of route parameters to deserialize

  Returns:

  the deserialized url parameter, can be null

• validateWildcardType

  public static void validateWildcardType(Class<?> navigationTarget,
                                          Class<?> parameterType)

  Validate that we can support the given wildcard parameter type.

  Parameters:

  navigationTarget - navigation target class

  parameterType - parameter type to check validity for usage with wildcard

• verifyParameters

  public static boolean verifyParameters(Class<?> navigationTarget,
                                         List<String> parameters)

  Verifies that the list of route parameters is valid for the given navigation target.

  Parameters:

  navigationTarget - the navigation target to verify against

  parameters - the list of route parameters to verify

  Returns:

  true if the parameters are valid, otherwise false

• getClassType

  public static Class<?> getClassType(Class<?> navigationTarget)

  Get the parameter type class.

  Parameters:

  navigationTarget - navigation target to get parameter type class for

  Returns:

  parameter type class

• isAnnotatedParameter

  public static boolean isAnnotatedParameter(Class<?> navigationTarget,
                                             Class<? extends Annotation> parameterAnnotation)

  Check if the parameter value is annotated as OptionalParameter.

  Parameters:

  navigationTarget - navigation target to check for optional

  parameterAnnotation - annotation to check parameter for

  Returns:

  parameter is optional
