| /** | ||
| * The EspIdfErrorParser class implements the IConsoleParser interface to parse console output for ESP-IDF errors and | ||
| * extract relevant hints. It processes each line of the console output and checks against a list of regular expression | ||
| * patterns to identify errors and their corresponding hints. | ||
| * | ||
| * This class maintains a list of regular expression hint pairs (ReHintPair) that are used to match and identify errors, | ||
| * and associate them with appropriate hints. It accumulates matched pairs in the 'allMatchesList' for further | ||
| * processing. | ||
| * | ||
| * The processLine method is responsible for processing each input line by iterating through the list of regular | ||
| * expression hint pairs. It uses regular expressions to determine if the line matches any error pattern. If a match is | ||
| * found, the corresponding hint is associated with the error message and added to the 'allMatchesList'. | ||
| * | ||
| * The shutdown method is used to trigger the completion of parsing. It notifies listeners registred in the UI plugin | ||
| * that the list of available hints has changed and providing the accumulated error hint pairs. The 'allMatchesList' is | ||
| * then cleared to prepare for the next parsing session. | ||

The constructor
EspIdfErrorParser(List<ReHintPair> reHintPairs)does not check if the passed listreHintPairsis null. This can lead to a NullPointerException in theprocessLinemethod when it tries to iterate overreHintsList. It's a good practice to validate constructor parameters to avoid potential runtime exceptions.
