LibSBML associates severity levels with every SBMLError object to provide an indication of how serious the problem is. Severities range from informational diagnostics to fatal (irrecoverable) errors. Given an SBMLError object instance, a caller can interrogate it for its severity level using methods such as SBMLError::getSeverity(), SBMLError::isFatal(), and so on. The present method encapsulates iteration and interrogation of all objects in an SBMLErrorLog, making it easy to check for the presence of error objects with specific severity levels.
