Protected Attributes | |
Direction | _dir |
Superclass for text based filtering algorithms.
This differs from Filter in that it has the concept of an algorithm that works in two directions, and supports operations on QString arguments.
QCA::TextFilter::TextFilter | ( | Direction | dir | ) |
Standard constructor.
dir | the Direction that this TextFilter should use. |
void QCA::TextFilter::setup | ( | Direction | dir | ) |
Reset the TextFilter.
dir | the Direction that this TextFilter should use. |
Direction QCA::TextFilter::direction | ( | ) | const |
The direction the TextFilter is set up to use.
MemoryRegion QCA::TextFilter::encode | ( | const MemoryRegion & | a | ) |
Process an array in the "forward" direction, returning an array.
This method runs in the forward direction, so for something like a Base64 encoding, it takes the "native" array, and returns that array encoded in base64.
a | the array to encode |
MemoryRegion QCA::TextFilter::decode | ( | const MemoryRegion & | a | ) |
QString QCA::TextFilter::arrayToString | ( | const MemoryRegion & | a | ) |
Process an array in the "forward" direction, returning a QString.
This is equivalent to encode(), except that it returns a QString, rather than a byte array.
a | the array to encode |
MemoryRegion QCA::TextFilter::stringToArray | ( | const QString & | s | ) |
Process an string in the "reverse" direction, returning a byte array.
This is equivalent to decode(), except that it takes a QString, rather than a byte array.
s | the array to decode |
QString QCA::TextFilter::encodeString | ( | const QString & | s | ) |
Process a string in the "forward" direction, returning a string.
This is equivalent to encode(), except that it takes and returns a QString, rather than byte arrays.
s | the string to encode |
QString QCA::TextFilter::decodeString | ( | const QString & | s | ) |
Process a string in the "reverse" direction, returning a string.
This is equivalent to decode(), except that it takes and returns a QString, rather than byte arrays.
s | the string to decode |
|
protected |
Internal state variable for the Direction that the filter operates in.
