<p>This class provides a logger for the Apple System Log facility.</p>
<p>As described in the “Getting Started” page,
the traditional NSLog() function directs its output to two places:</p>
<ul>
<li>Apple System Log</li>
<li>StdErr (if stderr is a TTY) so log statements show up in Xcode console</li>
</ul>
<p>To duplicate NSLog() functionality you can simply add this logger and a tty logger.
However, if you instead choose to use file logging (for faster performance),
you may choose to use a file logger and a tty logger.</p>

<p>This class provides a log formatter that filters log statements from a logging context not on the whitelist.</p>
<p>A log formatter can be added to any logger to format and/or filter its output.
You can learn more about log formatters here:
Documentation/CustomFormatters.md</p>
<p>You can learn more about logging context’s here:
Documentation/CustomContext.md</p>
<p>But here’s a quick overview / refresher:</p>
<p>Every log statement has a logging context.
These come from the underlying logging macros defined in DDLog.h.
The default logging context is zero.
You can define multiple logging context’s for use in your application.
For example, logically separate parts of your app each have a different logging context.
Also 3rd party frameworks that make use of Lumberjack generally use their own dedicated logging context.</p>

<p>This class provides a log formatter that prints the dispatch_queue label instead of the mach_thread_id.</p>
<p>A log formatter can be added to any logger to format and/or filter its output.
You can learn more about log formatters here:
Documentation/CustomFormatters.md</p>
<p>A typical <code>NSLog</code> (or <code><a href="Classes/DDTTYLogger.html">DDTTYLogger</a></code>) prints detailed info as <code>[<process_id>:<thread_id>]</code>.
For example:</p>
<p><code>2011-10-17 20:21:45.435 AppName[19928:5207] Your log message here</code></p>
<p>Where:
<code>- 19928 = process id</code>
<code>- 5207 = thread id (mach_thread_id printed in hex)</code></p>
<p>When using grand central dispatch (GCD), this information is less useful.
This is because a single serial dispatch queue may be run on any thread from an internally managed thread pool.
For example:</p>
<p><code>2011-10-17 20:32:31.111 AppName[19954:4d07] Message from my_serial_dispatch_queue</code>
<code>2011-10-17 20:32:31.112 AppName[19954:5207] Message from my_serial_dispatch_queue</code>
<code>2011-10-17 20:32:31.113 AppName[19954:2c55] Message from my_serial_dispatch_queue</code></p>
<p>This formatter allows you to replace the standard <code>[box:info]</code> with the dispatch_queue name.
For example:</p>
<p><code>2011-10-17 20:32:31.111 AppName[img-scaling] Message from my_serial_dispatch_queue</code>
<code>2011-10-17 20:32:31.112 AppName[img-scaling] Message from my_serial_dispatch_queue</code>
<code>2011-10-17 20:32:31.113 AppName[img-scaling] Message from my_serial_dispatch_queue</code></p>
<p>If the dispatch_queue doesn’t have a set name, then it falls back to the thread name.
If the current thread doesn’t have a set name, then it falls back to the mach_thread_id in hex (like normal).</p>
<p>Note: If manually creating your own background threads (via <code>NSThread/alloc/init</code> or <code>NSThread/detachNeThread</code>),
you can use <code>[[NSThread currentThread] setName:(NSString *)]</code>.</p>

<p>Most users will want file log messages to be prepended with the date and time.
Rather than forcing the majority of users to write their own formatter,
we will supply a logical default formatter.
Users can easily replace this formatter with their own by invoking the <code>setLogFormatter:</code> method.
It can also be removed by calling <code>setLogFormatter:</code>, and passing a nil parameter.</p>
<p>In addition to the convenience of having a logical default formatter,
it will also provide a template that makes it easy for developers to copy and change.</p>

<p><code>DDLogFileInfo</code> is a simple class that provides access to various file attributes.
It provides good performance as it only fetches the information if requested,
and it caches the information to prevent duplicate fetches.</p>
<p>It was designed to provide quick snapshots of the current state of log files,
and to help sort log files in an array.</p>
<p>This class does not monitor the files, or update it’s cached attribute values if the file changes on disk.
This is not what the class was designed for.</p>
<p>If you absolutely must get updated values,
you can invoke the reset method which will clear the cache.</p>

<p>The <code><a href="Protocols/DDLogger.html">DDLogger</a></code> protocol specifies that an optional formatter can be added to a logger.
Most (but not all) loggers will want to support formatters.</p>
<p>However, writing getters and setters in a thread safe manner,
while still maintaining maximum speed for the logging process, is a difficult task.</p>
<p>To do it right, the implementation of the getter/setter has strict requirements:</p>
<ul>
<li>Must NOT require the <code>logMessage:</code> method to acquire a lock.</li>
<li>Must NOT require the <code>logMessage:</code> method to access an atomic property (also a lock of sorts).</li>
</ul>
<p>To simplify things, an abstract logger is provided that implements the getter and setter.</p>
<p>Logger implementations may simply extend this class,
and they can ACCESS THE FORMATTER VARIABLE DIRECTLY from within their <code>logMessage:</code> method!</p>
