All Implemented Interfaces:

TreeVisitor

public class MethodNestingLevelVisitor
extends BaseTreeVisitor

Used to determine the deepest nesting level of a method, calculated starting from 0 and increased by 1 for each if, while, for, foreach, lambda, switch, and try block found nested within each other. This was designed to be used as a metric collector for design-oriented rules.
