	)			`[static]`

Finds method in class owner that contains given annotation. There must be at most one annotation of the given type in the class. If there are more methods that contain same annotation, RuntimeException is thrown. In this case, it would good to use getAnnotatedMethods(Class, Class) method

Parameters:

	owner
	annotation

Returns:

See also:: getAnnotatedMethods(Class, Class)

Gets field from class cls, either declared in cls or in one of its superclasses

Parameters:

	cls	- declaring class of the field
	fieldName	- name of the field

	)			throws NoSuchMethodException `[static]`

Gets method from class clz or any of its superclasses. If no method can be found NoSuchMethodException is raised.

Parameters:

	clz	- declaring class of the method
	methodName	- name of the method

Parameters:

	obj	- Object for which the method is going to be executed. Special if obj is of type java.lang.Class, method is executed as static method of class given as obj parameter
	method	- name of the object
	params	- actual parameters for the method

Returns:: - result of the method execution

If there is any problem with method invocation, a RuntimeException is thrown
