package jdk.internal.logger;

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.
