Detailed Description

Base32 encodes data using extended hex.

Converts data to base32 using extended hex alphabet. The alphabet is different than Base32Encoder.

Constructor & Destructor Documentation

◆ Base32HexEncoder()

Base32HexEncoder::Base32HexEncoder ( BufferedTransformation attachment = NULLPTR,
bool  uppercase = true,
int  groupSize = 0,
const std::string &  separator = ":",
const std::string &  terminator = "" 
)
inline

Construct a Base32HexEncoder.

Parameters
attachmenta BufferedTrasformation to attach to this object
uppercasea flag indicating uppercase output
groupSizethe size of the grouping
separatorthe separator to use between groups
terminatorthe terminator appeand after processing

Base32HexEncoder() constructs a default encoder. The constructor lacks fields for padding and line breaks. You must use IsolatedInitialize() to change the default padding character or suppress it.

Member Function Documentation

◆ IsolatedInitialize()

void Base32HexEncoder::IsolatedInitialize ( const NameValuePairs parameters)
virtual

Initialize or reinitialize this object, without signal propagation.

Parameters
parametersa set of NameValuePairs used to initialize this object

IsolatedInitialize() is used to initialize or reinitialize an object using a variable number of arbitrarily typed arguments. IsolatedInitialize() does not call Initialize() on attached transformations. If initialization should be propagated, then use the Initialize() function.

The following code modifies the padding and line break parameters for an encoder:

    Base32HexEncoder encoder;
    AlgorithmParameters params = MakeParameters(Pad(), false)(InsertLineBreaks(), false);
    encoder.IsolatedInitialize(params);

Reimplemented from BufferedTransformation.
