Class SpeedTestComplex

java.lang.Object

com.singularsys.jepexamples.diagnostics.SpeedTestComplex

public class SpeedTestComplex
extends java.lang.Object

Compares the speed of evaluation between different evaluation schemes. The standard class compares BigDecimal, Jep (with default Fast evaluator), the old StandardEvaluator, and RealEvaluator.

If you have some nice complicated examples, I'd love to hear about them to see if we can tune things up. - rich

Parameters:

outputter -

Method Detail

init

public void init()

fini

public void fini()

doAll

public void doAll(java.lang.String eqn,
                  java.lang.String[] varNames)

Run speed comparison for a single equation.

Parameters:

eqn - The equation to test

varNames - an array of variable names which will be set to random values.

doAll

public void doAll(java.lang.String[] eqns,
                  java.lang.String[] varNames)

Run speed comparison for a set of equations.

Parameters:

eqns -

varNames -

addConfig

public void addConfig(SpeedTestComplex.EvaluationConfig config)

Adds a new EvaluationConfig to be be run for comparison.

Parameters:

config -

main

public static void main(java.lang.String[] args)

Main method, executes all speed tests. Arguments '-pause' causes the program to wait for keyboard input before running test, useful use in profilers. Or a number specifying number of iterations to run.

Parameters:

args - Can contain '-pause' or NUM

runTests

public void runTests()

A standard set of tests.
