public RCBodyC

IntT n;

Size of the transform.

bool inv;

Is the transform backward ??

bool pwr2;

Is length a power of two ?

bool zeroPad;

Zero pad input to 'n' bytes ?

int primeFactors[];

int nf;

Number of factors. Sufficent for all 32-bit lengths.

FFT1dBodyC(int n,bool iinv,bool zeroPad = false)

Constructor.

~FFT1dBodyC()

Destructor

bool Init(int n,bool iinv)

Create a plan with the given setup.

Array1dC<ComplexC> Apply(const Array1dC<ComplexC> & dat)

Apply transform to array.
Note, only the first 'n' byte of dat are proccessed. if the array is shorter than the given length, an exception 'ErrorOutOfRangeC' will be thrown.

Array1dC<ComplexC> Apply(const Array1dC<RealT> & dat)

Apply transform to real array
Note, only the first 'n' byte of dat are proccessed. if the array is shorter than the given length, an exception 'ErrorOutOfRangeC' will be thrown.

IntT N() const

The size of the transform.

bool IsZeroPad() const

Test if we're doing zero padding.

UIntT References() const

Access count of handles open to this object.

RCBodyC & Copy() const

Make copy of body.
This should be provided in derived classes. this funtion will issue an assertion failure if called.

RCBodyC & DeepCopy(UIntT levels = ((UIntT))) const

Make a deep copy of body.
This should be provided in derived classes. this funtion will issue an assertion failure if called.

void IncRefCounter()

Increment reference counter.

bool DecRefCounter()

Decrement reference counter.
