Detailed Description

Abstract base class for a multi reader. To use this class you need to override MultiFileReader::getFactories.

Member Function Documentation

◆ addFile()

std::shared_ptr<adtf_file::Reader> adtfdat_processing::MultiFileReader::addFile ( const std::string &  file_name,
std::shared_ptr< adtf_file::SampleFactory sample_factory,
std::shared_ptr< adtf_file::StreamTypeFactory stream_type_factory 
)
protected

Adds a file to the multi file reader and opens the file if supported.

Parameters
file_namethe file path of the file
sample_factorythe sample factory to use for open call
stream_type_factorythe stream type factory for open call
Returns
std::shared_ptr<adtf_file::Reader> a valid reader if file is supported.
Exceptions
std::runtime_errorif no capable reader found for the given file_name.

◆ getFactories()

virtual adtf_file::ReaderFactories adtfdat_processing::MultiFileReader::getFactories ( ) const
protectedvirtual

Get all supported reader factories of this multireader.

Returns
adtf_file::ReaderFactories

◆ getItemCount()

std::optional<uint64_t> adtfdat_processing::MultiFileReader::getItemCount ( ) const
overridevirtual

Get the Item Count. This gets the overall count of all items (samples, stream types and triggers) of all streams.

Remarks
if it is not possible to retrieve the item count, return std::nullopt instead.
Returns
std::optional<uint64_t>

Reimplemented from adtf_file::Reader.

◆ getNextItem()

adtf_file::FileItem adtfdat_processing::MultiFileReader::getNextItem ( )
overridevirtual

Returns the next item of the file and increase the item index to the next one. These can be samples, streamtypes or trigger.

Returns
The next item.
Remarks
Use the given factories from the open call to create sample and streamtypes.
The Reader class is an interface where implementation should at least throw following exceptions in case of error:
Exceptions
exceptions::EndOfFileif end of file was reached
std::exceptionbased exception for any other implementation dependent case to identify error on getNextItem call

Implements adtf_file::Reader.

◆ getProgress()

std::optional<double> adtfdat_processing::MultiFileReader::getProgress ( ) const
overridevirtual

Get the Progress, a relative file position between 0.0 and 1.0.

Returns
std::optional<double> The relative value between 0.0 and 1.0 where internal file position is.

Reimplemented from adtf_file::Reader.

◆ getReaderIdentifier()

std::string adtfdat_processing::MultiFileReader::getReaderIdentifier ( ) const
overridevirtual

Get the Reader Identifier of the Reader.

Returns
the reader identifier

Implements adtf_file::Reader.

Reimplemented in adtfdat_processing::ReferencedFilesReader.

◆ getStreams()

std::vector<adtf_file::Stream> adtfdat_processing::MultiFileReader::getStreams ( ) const
overridevirtual

Get the Streams.

Returns
std::vector<Stream> A vector of all available streams.

Reimplemented from adtf_file::Reader.

◆ open()

void adtfdat_processing::MultiFileReader::open ( const std::string &  filename,
std::shared_ptr< adtf_file::SampleFactory sample_factory,
std::shared_ptr< adtf_file::StreamTypeFactory stream_type_factory 
)
overridevirtual

opens a file by the given filename. The given factories must be used to create samples and streamtypes for the getNextItem call

Parameters
filenameThe file to open
sample_factoryThe sample factory to create samples for the getNextItem call.
stream_type_factoryThe stream type factory to create streamtype for the getNextItem call.
Remarks
The Reader class is an interface where implementation should at least throw following exceptions in case of error:
Exceptions
std::exceptionbased exception for any other implementation dependent case to identify error on open call

Implements adtf_file::Reader.

Reimplemented in adtfdat_processing::ReferencedFilesReader.
