# A class describes the capabilities of an object, ie what data it has
|
|
# and functions it responds to
|
|
#
|
|
# An Object carries the data for the instance variables it has
|
|
# The Layout lists the names of the instance variables
|
|
# The class keeps a list of instance methods, these have a name and code
|
|
# The class also keeps a list of class methods (with names+code)
|
|
# Class methods are instance methods on the class object
|
|
|
|
# So it is essential that the class (the object defining the class)
|
|
# can carry methods. It does so as instance variables.
|
|
# In fact this property is implemented in the Object, as methods
|
|
# may be added to any object at run-time
|
