getResponseTimeInterval

public int getResponseTimeInterval()

Gets the responseTimeInterval

Returns:

Returns a int

setResponseTimeInterval

public void setResponseTimeInterval(int responseTimeInterval)

Sets the responseTimeInterval

Parameters:

responseTimeInterval - The responseTimeInterval to set

execute

public void execute()
             throws org.apache.tools.ant.BuildException

Overrides:

execute in class org.apache.tools.ant.Task

createAttributeCollatedResponseTimeChart

protected void createAttributeCollatedResponseTimeChart()
                                                 throws org.apache.tools.ant.BuildException

createResponseTimeGraph

protected void createResponseTimeGraph()
                                throws org.apache.tools.ant.BuildException

createGraphFrameBottom

protected void createGraphFrameBottom(java.io.FileWriter writer)
                               throws java.io.IOException

createGraphFrameTop

protected void createGraphFrameTop(java.io.Writer writer,
                                   int graphWidth,
                                   int graphHeight,
                                   java.lang.String xAxis,
                                   java.lang.String yAxis)
                            throws java.io.IOException

gatherMetrics

protected void gatherMetrics()
                      throws org.apache.tools.ant.BuildException

bellcurve

protected double bellcurve(double x,
                           double sigma,
                           double mu)

Mathematical formula for height of a normal curve.

The height (ordinate) of a normal curve is defined as:

where mu (m) is the mean and sigma (s) is the standard deviation, pi (p) is the constant 3.14159, and e is the base of natural logarithms and is equal to 2.718282.

x can take on any value from -infinity to +infinity.

f(x) is very close to 0 if x is more than three standard deviations from the mean (less than -3 or greater than +3).

poissonCurve

protected double poissonCurve(double x,
                              double mu)

validate

protected void validate()

Returns:

Returns a String

setAttributeName

public void setAttributeName(java.lang.String attributeName)

Sets the attributeName

Parameters:

attributeName - The attributeName to set
