Detailed Description

Hexadecimal encoding / decoding.

Examples

hextest.cpp, and randomtest.cpp.

Constructor & Destructor Documentation

Hex()

QCA::Hex::Hex

(

Direction

dir = Encode

)

Standard constructor.

Parameters

dir	the Direction that should be used.

Note

The direction can be changed using the setup() call.

Member Function Documentation

clear()

void QCA::Hex::clear ( )

overridevirtual

Reset the internal state.

This is useful to reuse an existing Hex object

Implements QCA::Filter.

update()

MemoryRegion QCA::Hex::update ( const MemoryRegion & a )

overridevirtual

Process more data, returning the corresponding encoded or decoded (depending on the Direction set in the constructor or setup() call) representation.

If you find yourself with code that only calls this method once, you might be better off using encode() or decode(). Similarly, if the data is really a string, you might be better off using arrayToString(), encodeString(), stringToArray() or decodeString().

Parameters

a	the array containing data to process

Implements QCA::Filter.

final()

MemoryRegion QCA::Hex::final ( )

overridevirtual

Complete the algorithm.

Returns

any remaining output. Because of the way hexadecimal encoding works, this will return a zero length array - any output will have been returned from the update() call.

Implements QCA::Filter.

ok()

bool QCA::Hex::ok ( ) const

overridevirtual

Test if an update() or final() call succeeded.

Returns

true if the previous call succeeded

Implements QCA::Filter.
