Method Detail

Iterate

public complex Iterate(complex pz)

Description copied from class: Transform

Transform a single point within a sequence

After a sequence has been set up with Init(), this function will be called once for each value in the sequence. Note that all values in the sequence must be processed in order (they cannot be processed out of order). If the sequence contains only one value, Init() will still be called and then Iterate() will be called just once.

Overrides:

Iterate in class Transform

Parameters:

pz - the complex value to be transformed

Returns:

the transformed value
