Value members

Concrete methods

def apply(poly: BitVector, initial: BitVector, reflectInput: Boolean, reflectOutput: Boolean, finalXor: BitVector): BitVector => BitVector

Constructs a table-based CRC function using the specified polynomial.

Constructs a table-based CRC function using the specified polynomial.

Each of the input vectors must be the same size.

Returns

function that calculates a n-bit CRC where n = poly.size

def bitwise(poly: BitVector, initial: BitVector, reflectInput: Boolean, reflectOutput: Boolean, finalXor: BitVector, value: BitVector): BitVector

Calculates a bitwise CRC of the specified value.

Calculates a bitwise CRC of the specified value.

If calculating a lot of CRCs, prefer the apply method, which precomputes a lookup table and uses it in each CRC calculation.

Returns

function that calculates a n-bit CRC where n = poly.size

def int32(poly: Int, initial: Int, reflectInput: Boolean, reflectOutput: Boolean, finalXor: Int): BitVector => Int

Constructs a 32-bit, table-based CRC function using the specified polynomial.

Constructs a 32-bit, table-based CRC function using the specified polynomial.

Returns

function that calculates a 32-bit CRC
