This project has moved to javadelight/delight-log.

Async Log is a minimal implementation for asynchronous logging in Java.

Why: To provide a logging implementation works well in multi-threaded environments with minimal performance impact.

What Not: This library is very feature-poor by design to keep it maintainable and portable.

All logs are held in a log repository which can be created as follows.

PropertyNode logs = Logs.create();

Note: Before the application terminates the log repository should always be finalized as follows to ascertain that the thread used by the logging node is released.

logs.stop().get();

The following will log a number of simple Strings.

logs.record(Logs.string("log1", "entry 1"));
logs.record(Logs.string("log1", "entry 2"));

The entries written in the previous example can be retrieved as follows:

String log1 = logs.retrieve("log1", StringLog.class).get().toString();

System.out.println(log1);

This results in an output as follows:

[
    'entry1',
    'entry1'
]

By default individual logs are limited to 40 items. If this limit is reached, the oldest values will be purged.

A custom limit can be set by passing an integer to the logs constructor method:

PropertyNode limitedLog = Logs.create(20);
