package jdk.internal.logger;

import java.util.ResourceBundle;
import java.util.function.Supplier;
import java.lang.System.Logger;
import java.lang.System.Logger.Level;

This implementation of Logger redirects all logging method calls to calls to log(Level, String, ResourceBundle, ...) methods, passing the Logger's ResourceBundle as parameter. So for instance a call to log(Level.INFO, msg) will be redirected to a call to this.log(Level.INFO, this.bundle, msg, (Object[]) null).

Note that methods that take a Supplier<String> or an Object are not redirected. It is assumed that a string returned by a Supplier<String> is already localized, or cannot be localized.

Type parameters:
  • <L> – Type of the wrapped Logger: Logger or an extension of the Logger interface.
