How to fix Duplicated Code Complexity

Duplicated Code

Duplicate code is one of the most pungent code smells. A rule that is often used is to re-structure code once it is duplicated in three or more places.

Common duplication problems, and corresponding solutions are:

If you have the same expression in different places: Extract expression to a method
If you have the same method in different sub-classes: Extract method, and pull up field to the parent class
If you have the same code in unrelated classes: Consider extracting the code to a new class, and injecting that class

Complex Class

Tip: Before tackling complexity, make sure that you eliminate any duplication first. This often can reduce the size of classes significantly.

Complex classes like Logger often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes. You can also have a look at the cohesion graph to spot any un-connected, or weakly-connected components.

Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.

While breaking up the class, it is a good idea to analyze how other classes use Logger, and based on these observations, apply Extract Interface, too.

/**
 * Xoops\Core\Logger - dispatch log requests to any registered loggers.
 *
 * No logging is done in this class, but any logger, implemented as a
 * module or extension, can register as a logger using the addLogger()
 * method. Multiple loggers can be registered, and each will be
 * invoked in turn for each log() call.
 *
 * Such loggers are expected to implement the PSR-3 LoggerInterface.
 * In addition, any logger that generates output as part of the XOOPS
 * delivered page should implement the quiet() method, to disable output.
 *
 * Loggers are managed this way so that any routine may easily add a
 * log entry without needing to know any details of the implementation.
 *
 * Not all events are published through this mechanism, only specific requests
 * to log() or related methods. Individual loggers may listen for events (i.e.
 * preloads) or other sources and gain access to detailed debugging information.

18			* Xoops\Core\Logger - dispatch log requests to any registered loggers.
19			*
20			* No logging is done in this class, but any logger, implemented as a
21			* module or extension, can register as a logger using the addLogger()
22			* method. Multiple loggers can be registered, and each will be
23			* invoked in turn for each log() call.
24			*
25			* Such loggers are expected to implement the PSR-3 LoggerInterface.
26			* In addition, any logger that generates output as part of the XOOPS
27			* delivered page should implement the quiet() method, to disable output.
28			*
29			* Loggers are managed this way so that any routine may easily add a
30			* log entry without needing to know any details of the implementation.
31			*
32			* Not all events are published through this mechanism, only specific requests
33			* to log() or related methods. Individual loggers may listen for events (i.e.
34			* preloads) or other sources and gain access to detailed debugging information.
