constructor

public REB_SJManowar_Switch()
Method Detail

### Init

public complex Init(complex pz)
initialize the formula

Overrides:
Init in class Switch
Parameters:
pz - seed value for the sequence; for a normal fractal formula, this will be #pixel
Returns:
first value in the sequence; this corresponds to #z in a fractal formula

### Iterate

public complex Iterate(complex pz)
call for each iterated point

Overrides:
Iterate in class Switch
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)
Override the default function for bailout

Overrides:
IsBailedOut in class Switch
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)
