Constructor Details

AdaptiveLineStopper

public AdaptiveLineStopper(double[] u0,
 double sf,
 Line targetLine,
 double accuracy,
 SwimTrajectory trajectory)

Line stopper (does check max path length)

Parameters:

u0 - initial state vector

sf - the maximum value of the path length in meters

targetLine - the target line

accuracy - the accuracy in meters

trajectory - optional swim trajectory (can be null)

Method Details

stopIntegration

public boolean stopIntegration(double snew,
 double[] unew)

Description copied from interface: IAdaptiveStopper

Given the current state of the integration, should we stop? This allows the integration to stop, for example, if some distance from the origin has been exceeded or if the independent variable passes some threshold. It won't be precise, because the check may not happen on every step, but it should be close.

Returns:

true if we should stop now.

accept

protected void accept(double snew,
 double[] unew)

Accept a new integration step

Overrides:

accept in class AAdaptiveStopper

Parameters:

snew - the new value of s in meters

unew - the new state vector
