graphnet_file_reader

Module containing different FileReader classes in GraphNeT.

These methods are used to open and apply Extractors to experiment-specific file formats.

class graphnet.data.readers.graphnet_file_reader.GraphNeTFileReader(name, class_name, level, log_folder, **kwargs)

Bases: Logger, ABC

A generic base class for FileReaders in GraphNeT.

Classes inheriting from GraphNeTFileReader must implement a __call__ method that opens a file, applies `Extractor`(s) and returns a list of ordered dictionaries.

In addition, Classes inheriting from GraphNeTFileReader must set class properties accepted_file_extensions and accepted_extractors.

Construct Logger.

Parameters:

• name (str | None)

• class_name (str | None)

• level (int)

• log_folder (str | None)

• kwargs (Any)

property accepted_file_extensions: List[str]

Return list of accepted file extensions.

property accepted_extractors: List[Extractor]

Return list of compatible `Extractor`(s).

property extracor_names: List[str]

Return list of table names produced by extractors.

find_files(path)

Search directory for input files recursively.

This method may be overwritten by custom implementations.

Parameters:

path (Union[str, List[str]]) – path to directory.

Return type:

Union[List[str], List[I3FileSet]]

Returns:

List of files matching accepted file extensions.

set_extractors(extractors)

Set `Extractor`(s) as member variable.

Parameters:

extractors (Union[List[Extractor], List[I3Extractor], List[ParquetExtractor], List[H5Extractor], List[PrometheusExtractor]]) – A list of `Extractor`(s) to set as member variable.

Return type:

None

validate_files(input_files)

Check that the input files are accepted by the reader.

Parameters:

input_files (Union[List[str], List[I3FileSet]]) – Path(s) to input file(s).

Return type:

None
