	Determines whether a log entry should be filtered out.

Detailed Description

Filter that passes through error-level log messages only.

As the name implies, a filterable class that only allows error-level logs to pass through. When this filter is registered with logger, warning and info logs will not be output.

Not used directly; instead, create an instance and add it to logger.

Usage

Example of using errPassFilter:

const filters& prevFilters = logger::get().getFilters();
filters fs(new errPassFilter());
logger::get().setFilters(fs);
 
// Now only error-level logs will be output
 
logger::get().setFilters(prevFilters); // Restore previous filters
