Constructor & Destructor Documentation

FileListConsumer()

libcdoc::FileListConsumer::FileListConsumer ( const std::string &  base_path )

inline

Member Function Documentation

close()

result_t libcdoc::FileListConsumer::close ( )

inlinefinaloverridevirtual

informs DataConsumer that the writing is finished

Returns

error code or OK

Implements libcdoc::DataConsumer.

References libcdoc::OK, and libcdoc::OUTPUT_STREAM_ERROR.

isError()

bool libcdoc::FileListConsumer::isError ( )

inlinefinaloverridevirtual

checks whether DataSource is in error state

Returns

true if error state

Implements libcdoc::DataConsumer.

open()

result_t libcdoc::FileListConsumer::open ( const std::string &  name, int64_t  size  )

inlinefinaloverridevirtual

create a new named sub-stream

Creates a new named sub-stream. It is up to implementation to handle the name and optional size.

Parameters

name	the name of sub-stream
size	the size of sub-stream or -1 if unknown at creation time

Returns

error code or OK

Implements libcdoc::MultiDataConsumer.

References libcdoc::OK, and libcdoc::OUTPUT_STREAM_ERROR.

write()

result_t libcdoc::FileListConsumer::write ( const uint8_t *  src, size_t  size  )

inlinefinaloverridevirtual

write write bytes to output object

The following invariant holds: If there was no error then result == size If there was an error then result < 0

Parameters

src	source block
size	the number of bytes to write

Returns

size or error code

Implements libcdoc::DataConsumer.

References libcdoc::OUTPUT_STREAM_ERROR.
