                                    java.lang.Class<?> annotationType)
        Tells whether the given node has an annotation of the given type.
        Parameters:
        node - an AST node
        annotationType - an annotation type
        Returns:
        true iff the given node has an annotation of the given type

        Parameters:
        method - a method (node)
        Returns:
        a list of statements of the given method
