The methodsOf function returns the Methods Structure for a the specified class object {class}.

The Methods Structure exists for all class Structures and class Lambdas. It contains method bindings, which are the method name, and the Lambda that is associated with the method. The Methods Structure is updated any time a defmethod macro is invoked.

For instance below we define a class Lambda, create an object of the class, and then use the methodsOf function to return the class methods.

(defclass employee()
   svars:(String:Name (Number:Salary 0.0))
   (defun new(self name salary)
      (setq Name (string name))
      (setq Salary salary)
      self) ;; end of new method
   (defun talk(self)
      (writeln "I " Name " am an employee.")
      true) ;; end of talk method

   ;;.... other class methods here

   true) ;; end of employee class

(defclass employee:manager()
   (defun talk(self)
      (writeln "I " Name " am a manager.")
      true) ;; end of talk method

   ;;.... other class methods here

   true) ;; end of manager class

;; Finding the class name of an object created by a class Lambda
(setq emp (new employee "John Doe" 24000.0)) ;; Create an object of class employee
(setq mgr (new manager "Chuck Bigman" 36000.0)) ;; Create an object of class manager

;; Finding the class methods of an object.
(refAttributed (methodsOf emp)) ;; returns #(obj| new talk )
((methodsOf mgr)[talk:] mgr) ;; writes on the console, "I Chuck Bigman am a manager."


Since the methodsOf function returns the Methods Structure object, it is usually used in conjunction with other functions to retrieve the information about the class Methods. The length function will determine how many methods exist for the class. The isMember function will determine if the specified method is in the Methods Structure.
