Constructor Detail

MMF_SwitchMagnet2

public MMF_SwitchMagnet2(Generic pparent)

Parameters:

pparent - the parent, generally "this" for the parent, or zero

MMF_SwitchMagnet2

public MMF_SwitchMagnet2()

Method Detail

Iterate

public complex Iterate(complex pz)

Description copied from class: ConvergentDivergentFormula

Produce the next value in the sequence

As long as the sequence has not bailed out, this function will be continually called to produce sequence values.

Overrides:

Iterate in class ConvergentDivergentFormula

Parameters:

pz - previous value in the sequence; corresponds to #z in a fractal formula. Note that you should always use this value for computing the next iteration, rather than a saved value, as the calling code may modify the returned value before passing it back to the next Iterate() call.

Returns:

the next value in the sequence

IsBailedOut

public boolean IsBailedOut(complex pz)

Description copied from class: ConvergentDivergentFormula

Test whether the formula has bailed out (i.e. the sequence is complete)

Since this is a divergent fractal, the test is easy: if it's bigger than the bailout, the sequence is done.

Overrides:

IsBailedOut in class ConvergentDivergentFormula

Parameters:

pz - last sequence value to test; this should be the value returned from the previous Iterate() call. Note that it is acceptable to ignore pz and use m_BailedOut, but any code calling IsBailedOut() should pass in the correct pz for Formula classes which do not use m_BailedOut.

Returns:

true if the sequence has bailed out (i.e. should be terminated)

GetUpperBailout

public float GetUpperBailout()

Description copied from class: ConvergentDivergentFormula

Determine the upper bailout boundary.

Overrides:

GetUpperBailout in class ConvergentDivergentFormula

Returns:

the upper bailout parameter

GetLowerBailout

public float GetLowerBailout()

Description copied from class: ConvergentDivergentFormula

Determine the lower bailout boundary.

Overrides:

GetLowerBailout in class ConvergentDivergentFormula

Returns:

the lower bailout parameter
