@FunctionalInterface public interface Filter
A Filter can be used to provide fine grain control over what is logged, beyond the control provided by log levels.

Each Logger and each Handler can have a filter associated with it. The Logger or Handler will call the isLoggable method to check if a given LogRecord should be published. If isLoggable returns false, the LogRecord will be discarded.
