Member Function Documentation

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

virtual

Decode data.

Parameters

in	input data (encoded)
out	output stream for decoded data
progress	progress listener, or NULL if you do not want to receive progress notifications

Returns

number of bytes written into output stream

Implements encoder.

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

virtual

Encode data.

Parameters

in	input data (decoded)
out	output stream for encoded data
progress	progress listener, or NULL if you do not want to receive progress notifications

Returns

number of bytes written into output stream

Implements encoder.

References vmime::count(), inputStream::eof(), encoder::getProperties(), propertySet::getProperty(), progressListener::progress(), inputStream::read(), inputStream::reset(), b64Encoder::sm_alphabet, progressListener::start(), progressListener::stop(), and outputStream::write().

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

n	count 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

n	count of input (decoded) bytes

Returns

count of output (encoded) bytes

Implements encoder.
