Class PreBootstrapLoggingEvent

java.lang.Object

org.apache.juli.logging.impl.PreBootstrapLoggingEvent

public class PreBootstrapLoggingEvent
extends Object

Helper class for PreBootstrapLogger that stores timestamped logging events, and later flushes them to Logback appenders.

At instance level, we implement here an immutable holder for a logging event that might occur at pre-bootstrap time, i.e. before the actual logging system is initialized.

At class level, all created instances are stored in a FIFO queue, so that they can be flushed to Logback appenders once the logging system is bootstrapped.

This class does not implement thread safety. It's the responsibility of client code to properly synchronize calls to these two methods, using a single lock:

• add(String, String, int, String, Throwable)
• flushEvents(ClassLoader)

Typically, facade loggers SLF4JDelegatingLog do (globally) synchronize access to PreBootstrapLogger, which implies synchronized access to this class. See the documentation of these classes for more details.

Diagnostics can be activated by lowering the SLF4JDelegatingLog.diagnostics level.

Since:

1.1.0
