Class Statement Control Property

When LW Python sees a "class" statement, it will set an entry in the "Control" map to note that LW Python is entering the "class" body. More formally,

if the following are true:

  • the line at time t = i
  • the tab at time t = j
  • statement at line i, tab j = a class named name with bases: bases

then Control Map at time (t + 1) = result of storing (pair ("class", name)) at key: j in map: (Control Map at time t)

For example,

if the following are true:

  • the line at time 0 = 1
  • the tab at time 0 = 0
  • statement at line 1, tab 0 = class Person:

then Control Map at time (0 + 1) = result of storing (pair ("class", "Person")) at key: 0 in map: (Control Map at time 0)

The new entry in the "Control" map stores the current tab as the key and the pair class:Person as the value. Try stepping through the simulator to see LW Python update the "Control" map.
