  • Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

    @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.
