Member Function Documentation

size_t decode ( utility::inputStream &  in,
utility::outputStream &  out,
utility::progressListener *  progress = NULL 
)
virtual

Decode data.

Parameters
ininput data (encoded)
outoutput stream for decoded data
progressprogress listener, or NULL if you do not want to receive progress notifications
Returns
number of bytes written into output stream

Implements encoder.

References inputStream::eof(), encoder::getProperties(), propertySet::getProperty(), progressListener::progress(), inputStream::read(), inputStream::reset(), qpEncoder::sm_hexDecodeTable, and progressListener::stop().

size_t encode ( utility::inputStream &  in,
utility::outputStream &  out,
utility::progressListener *  progress = NULL 
)
virtual

Encode data.

Parameters
ininput data (decoded)
outoutput stream for encoded data
progressprogress listener, or NULL if you do not want to receive progress notifications
Returns
number of bytes written into output stream

Implements encoder.

References inputStream::eof(), encoder::getProperties(), propertySet::getProperty(), progressListener::progress(), inputStream::read(), inputStream::reset(), qpEncoder::sm_RFC2047EncodeTable, progressListener::start(), and progressListener::stop().

const std::vector< string > getAvailableProperties ( ) const
virtual

Return a list of property names that can be set for this encoder.

Returns
list of property names

Reimplemented from encoder.

References encoder::getAvailableProperties().

size_t getDecodedSize ( const size_t  n) const
virtual

Return the encoded size for the specified input (encoded) size.

If the size is not exact, it may be an estimate which should always be larger than the actual decoded size.

Parameters
ncount of input (encoded) bytes
Returns
count of output (decoded) bytes

Implements encoder.

size_t getEncodedSize ( const size_t  n) const
virtual

Return the encoded size for the specified input (decoded) size.

If the size is not exact, it may be an estimate which should always be larger than the actual encoded size.

Parameters
ncount of input (decoded) bytes
Returns
count of output (encoded) bytes

Implements encoder.
