\Zxing\Common\ReedsolomonReedSolomonDecoder

<p>Implements Reed-Solomon decoding, as the name implies.</p>

The algorithm will not be explained here, but the following references were helpful in creating this implementation:

Much credit is due to William Rucklidge since portions of this code are an indirect port of his C++ Reed-Solomon implementation.

Methods

__construct()

__construct(mixed  $field) : mixed

Parameters

mixed $field

Returns

mixed —

decode()

decode(mixed  $received, mixed  $twoS) : mixed

<p>Decodes given set of received codewords, which include both data and error-correction codewords. Really, this means it uses Reed-Solomon to detect and correct errors, in-place, in the input.</p>

Parameters

mixed $received
mixed $twoS

Throws

\Zxing\Common\Reedsolomon\ReedSolomonException

if decoding fails for any reason

Returns

mixed —

runEuclideanAlgorithm()

runEuclideanAlgorithm(mixed  $a, mixed  $b, mixed  $R) : mixed

Parameters

mixed $a
mixed $b
mixed $R

Returns

mixed —

findErrorLocations()

findErrorLocations(mixed  $errorLocator) : mixed

Parameters

mixed $errorLocator

Returns

mixed —

findErrorMagnitudes()

findErrorMagnitudes(mixed  $errorEvaluator, mixed  $errorLocations) : mixed

Parameters

mixed $errorEvaluator
mixed $errorLocations

Returns

mixed —
