scan Method

Scans the compressed archive.

Syntax

def scan() -> None: ...

Remarks

This method will scan the gzip archive specified by archive_file. The archive will be read, the header will be checked, and the stored filename will be written to file_compressed_name.

Unlike in the Zip, Tar, and Jar classs, it is never necessary to invoke this method, and it will not be automatically invoked by extract. Suggested uses for this method would be to check that the file is a gzip file, or to determine an appropriate value for file_decompressed_name.
