Method Summary

double	errorEstimate() Returns the error estimate for the integral value.
long	functionCalls() Returns the number of times the integrand function has been evaluated.
java.util.Set<IntegrationInfo>	supplementalInfo() Returns a set of integration information that provide supplementary or additional information on the integration process and result.
double	value() Returns the estimated integral value.

Method Detail
