Detailed Description

Functions used to undo operations.

Description:

There are two lists which hold:

  • information about a command
  • data of removed objects

Both lists are organized as first-in-last-out which means that the undo list can always use the last entry of the remove list.

A serial number is incremented whenever an operation is completed.

An operation itself may consist of several basic instructions.

E.g.: removing all selected objects is one operation with exactly one serial number even if the remove function is called several times.

Note:
A lock flag ensures that no infinite loops occur.
