MovableObject

A Timer object is an object which can be used to measure system resources, i.e. cpu time and memory usage. Currently for Unix systems only. COMPILE FLAG NEEDED.

Does nothing.

Sets the accounting variables to mark the start of accounting period using the unix functions times() and getrusage.

Sets the accounting variables to mark the end of accounting period using the unix functions times() and getrusage. Uses the difference between the starting and ending accounting variables to determine the elapsed real time between the last calls to start() and pause(). Returns this value in units of seconds.

Uses the difference between the starting and ending accounting variables to determine the CPU time allocated the process between the last calls to start() and pause(). Returns this value in units of seconds.

Uses the difference between the starting and ending accounting variables to determine the number of page faults that required reading of pages from disk between the last calls to start() and pause(). Returns this value.

Uses the difference between the starting and ending accounting variables to determine the real time, CPU time, operating system time allocate the process, total number of page faults, number of page faults that required reading of pages from memory, and number of page faults that required no reading from disk between the last calls to start() and pause(). Send these values to s.

Invokes Print(s) on the Timer object E.
