/**
 * This class represents profiling event information for a syntax error
 * identified during prediction.
 *
 * Syntax errors occur when the prediction algorithm is unable to identify
 * an alternative which would lead to a successful parse.
 *
 * @param decision The decision number
 * @param configs The final configuration set reached during prediction
 *   prior to reaching the [ATNSimulator.ERROR] state
 * @param input The input token stream
 * @param startIndex The start index for the current prediction
 * @param stopIndex The index at which the syntax error was identified
 * @param fullCtx `true` if the syntax error was identified during LL
 *   prediction, otherwise `false` if the syntax error was identified
 *   during SLL prediction
 *
 * @see Parser.notifyErrorListeners
 * @see ANTLRErrorListener.syntaxError
