  • Method Details

    • isAssignableFrom

      public static boolean isAssignableFrom(Class<?> assignableClass, Class<?> objectClass)
      Checks whether the given class parameter is assignable from the given object class parameter
      Parameters:
      assignableClass - class to use for assignable to
      objectClass - class to use for assignable from
      Returns:
      true if the object class is of type assignable class, false if not

    • empty

      public static boolean empty(Object value)
      Checks whether the given value is null or blank string
      Parameters:
      value - property value to check
      Returns:
      true if value is null or blank, false if not

    • emptyList

      public static boolean emptyList(List<?> list)
      Checks to see if the list is empty. Throws a RuntimeException if list is not a List.
      Parameters:
      list - the list
      Returns:
      true if the list is null or empty, false otherwise

    • getService

      public static <T> T getService(String serviceName)
      Returns the service indicated by serviceName.
      Type Parameters:
      T - the type of the service
      Parameters:
      serviceName - the name of the service to obtain
      Returns:
      the service indicated by serviceName.

    • listContains

      public static boolean listContains(List<?> list, Object[] values)
      Check to see if the list contains the values passed in.

      In the SpringEL call values can be single item or array due to the way the EL converts values. The values can be string or numeric and should match the content type being stored in the list. If the list is String and the values passed in are not string, toString() conversion will be used. Returns true if the values are in the list and both lists are non-empty, false otherwise.

      Parameters:
      list - the list to be evaluated
      values - the values to be to check for in the list
      Returns:
      true if all values exist in the list and both values and list are non-null/not-empty, false otherwise

    • getName

      public static String getName(Class<?> clazz)
