@FunctionalInterface @InternalApi public interface Supplier<T> extends Supplier<T>
Consider this class private. Classes implementing this interface know how to supply a value.

This is a functional interface intended to support lambda expressions in log4j 2.

Implementors are free to cache values or return a new or distinct value each time the supplier is invoked.

DEPRECATED: this class will be removed in 3.0 to be replaced with the Java 8 interface.
