DESIRED_LENGTH
Indicate that a length argument represents the desired length for the real and imaginary arrays used as inputs or outputs to a transform. Subject to other constraints,FFT.getServiceName(int,boolean,LMode)
will choose an FFT provider that can provide a transform with a length as large or larger than the desired length, but as close to the desired length as possible. -
EXACT_LENGTH
Indicate that the length argument represents a a length that the FFT provider must support. Subject to other constraints,FFT.getServiceName(int,boolean,LMode)
will choose an FFT provider that can provide a transform with a length with the specified value. -
MAX_LENGTH
Indicate that a length argument represents the maximum length for the real and imaginary arrays used as inputs or outputs to a transform. Subject to other constraints,FFT.getServiceName(int,boolean,LMode)
will choose an FFT provider that can provide a transform with a length as large or larger than the maximum length.
