Method Detail

getMeanValue

public double getMeanValue()

Returns the meanValue.

Returns:

double

doOneIteration

protected abstract void doOneIteration()
                                throws java.lang.Exception

Sub-classes should override this to perform the operation to be measured.

Throws:

java.lang.Exception

getCurrentConfidence

protected double getCurrentConfidence()

Returns the current confidence level.

Returns:

the current confidence level.

getMarginOfError

protected double getMarginOfError()

Returns the current margin of error.

Returns:

the current margin of error.

getStandardDeviationP

protected double getStandardDeviationP()

Returns the current STDDEV.

Returns:

the current STDDEV

addResult

protected void addResult(double value)

Adds one test result to the statistics.

Parameters:

value - a single result representing the value being measured in the test.

doIterations

protected void doIterations(int num_iterations)
                     throws java.lang.Exception

Calls doIteration() the numIterations times, displaying the mean, std, margin of error and confidence level.

Parameters:

num_iterations - the number of iterations to perform ( < 30)

Throws:

java.lang.Exception - if an error occurs.

reportResults

protected void reportResults(java.lang.String additionalMessage)

Reports the current results to STDOUT, preceeded by additionalMessage if not null.

Parameters:

additionalMessage - the additional message to print, or null if no message.

getConfidenceLookup
