java.lang.Object

```
public final class GenericGF
extends java.lang.Object
```
This class contains utility methods for performing mathematical operations over the Galois Fields. Operations use a given primitive polynomial in calculations.

Throughout this package, elements of the GF are represented as an int for convenience and speed (but at the cost of memory).

public GenericGF(int primitive,

                 int b)
```
    Create a representation of GF(size) using the given primitive polynomial.
    
    参数:
    
    primitive - irreducible polynomial whose coefficients are represented by the bits of an int, where the least-significant bit represents the constant coefficient
    
    size - the size of the field
    
    b - the factor b in the generator polynomial can be 0- or 1-based (g(x) = (x+a^b)(x+a^(b+1))...(x+a^(b+2t-1))). In most cases it should be 1, but for QR code it is 0.
