getCloseEncounter

public boolean getCloseEncounter()

main

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

flatten

public static final double[] flatten(double[][] source)

printTable

public static void printTable(java.io.PrintStream out,
                              double[] table,
                              java.lang.String fmt)

advance

public final double advance(double timeInterval,
                            double tstep)

advance

public final double advance(double[][] xyzParam,
                            double timeInterval,
                            double tstep)

Description copied from interface: Integrator

Advances the system by the specified time, using xyzParam as initial (r, v). xyzParam is a pointer to the xyzParam field in StellarSystem, so before finishing xyzParam should be set to the new (r, v).

Specified by:

advance in interface Integrator

Parameters:

xyzParam - Input / output coordinates

timeInterval - Amount of time to evolve for.

tstep - Timestep hint.

Returns:

Last timestep used.

hasCloseEncounter

public boolean hasCloseEncounter()

Description copied from interface: Integrator

Specifies if a close encounter happened during the last advance().

Specified by:

hasCloseEncounter in interface Integrator

Returns:

True if a close encounter happened.
