compare_time_function(Real base,Charstring msg,Charstring fn,Vector args,
                     Integer times)->Boolean

The relative time spent to call the OSQL function fn with arguments args n times compared to the corresponding base time per call base. The systen will print a message msg and the both the total time and the improvement factor compared to base

---

compare_time_query(Real base,Charstring text,Charstring query,Integer times)
                  ->Real

---

expanded_image(Function f)->Integer

---

pp(Object o)->Charstring

Pretty print object o into a string

---

print(Object o)->Boolean

Print object o on console

---

profile()->Vector of (Charstring,Number)

return statistical profile as Vector of pairs [fnname,percentage]

---

profiling(Charstring action)->Charstring

Control statistical profiling by action: on: turn on statistical profiling of OSQL functions all: turn on statistical prifiling of OSQL and Lisp off: turn off statistical profiling clear: clear collected samples print: print percentage time spent in functions

---

test_server_connection()->Bag of Charstring msg

---

time_function(Charstring msg,Charstring fn,Vector args,Integer times)->Real

The time spent to call the OSQL function fn with arguments args n times. The systen will print a message msg and the total time on the console. The result is the time spent per call

---

time_query(Charstring text,Charstring query,Integer times)->Real

---

trace(Charstring fn)->Function

Trace function named fn. Derived functions cannot be traced!

---

untrace(Charstring fn)->Function

Untrace function named fn
