tex2html_wrap_inline7610 List<Signal> signals: This private member acts as a repository for all the signals which have been transmitted through the wire during the course of the simulation. It is simply a linked list of Signal objects.
tex2html_wrap_inline7610 void display_signals(): This helper method employed by show_signals() iterates over the signal list and displays all the signal values and times currently on the wire. Only the changes in signal values are actually displayed by this function.
tex2html_wrap_inline7610 void replace(Signal sig): This function is used to replace a signal in the list with the specified signal. It is intended for use during the simulation of zero-delay elements but is not used by the current implementation.
