    • methodsDeclaredIn

      public static Method[] methodsDeclaredIn(Class<?> cls, Class<?>... additionalClasses)
      Get all methods in a class hierarchy of the supplied classes. Both declared an non-declared (no duplicates).
      Parameters:
      cls - The class whose methods to get.
      additionalClasses - Additional classes whose methods to get.
      Returns:
      All methods declared in this class hierarchy.
    • method

      public static Method method(Class<?> declaringClass, String methodName, Class<?>... parameterTypes)
      Get a method when it cannot be determined by methodName or parameter types only.

      The method will first try to look for a declared method in the same class. If the method is not declared in this class it will look for the method in the super class. This will continue throughout the whole class hierarchy. If the method is not found an IllegalArgumentException is thrown.

      Parameters:
      declaringClass - The declaringClass of the class where the method is located.
      methodName - The method names.
      parameterTypes - All parameter types of the method (may be null).
      Returns:
      A java.lang.reflect.Method.
      Throws:
      MethodNotFoundException - If a method cannot be found in the hierarchy.
    • method

      public static Method method(Class<?> declaringClass, Class<?>... parameterTypes)
      Get a method without having to specify the method name.

      The method will first try to look for a declared method in the same class. If the method is not declared in this class it will look for the method in the super class. This will continue throughout the whole class hierarchy. If the method is not found an IllegalArgumentException is thrown. Since the method name is not specified an IllegalArgumentException is thrown if two or more methods matches the same parameter types in the same class.

      Parameters:
      declaringClass - The declaringClass of the class where the method is located.
      parameterTypes - All parameter types of the method (may be null).
      Returns:
      A java.lang.reflect.Method.
      Throws:
      MethodNotFoundException - If a method cannot be found in the hierarchy.
      TooManyMethodsFoundException - If several methods were found.
    • methods

      public static Method[] methods(Class<?> clazz, String methodName, String... additionalMethodNames)

      additionalMethodNames - Additional names of the methods that will be returned.
      Returns:
      An array of Method's. May be of length 0 but not null.
      Throws:
      MethodNotFoundException - If no method was found.
    • methods

      MethodNotFoundException - If no method was found.
    • field

      public static Field field(Class<?> declaringClass, String fieldName)
      Get a field from a class.

      The method will first try to look for a declared field in the same class. If the method is not declared in this class it will look for the field in the super class. This will continue throughout the whole class hierarchy. If the field is not found an IllegalArgumentException is thrown.

      Parameters:
      declaringClass - The declaringClass of the class where the method is located.
      fieldName - The method names.
