- Description:
This module contains the JPLMWrapper class, which extends the CodecWrapper class to provide specific encoding and decoding functionality for the JPLM codec.
- get_data_from_preffix(file_lines, preffix)[source]
Extracts the value from a log line that starts with the given prefix.
- Parameters:
file_lines (List[str]) – List of lines from the log file
preffix (str) – Prefix string to search for at the start of lines
- Returns:
The value after the prefix, or empty string if not found
- Return type:
str
