If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

CSHARP.CLASS.CLONE.SCNC : clone Subclass of Non-clonable (C#)

要旨

A subclass of a non-cloneable class may be cloned.

This checker identifies frequent problems in the definition of the method Clone(). That method is used to generate a clone of an object, that is, a distinct instance with the same behavior as the original one. The default implementation in System.Object checks that the object to clone implements the interface System.ICloneable or otherwise throws an exception. Hence, in order to clone an object it is in general enough to implement that interface and use the default implementation of Clone(). It is also possible to override that default implementation. Note that a class that inherits the default implementation allows its subclasses to implement System.ICloneable and clone its instances.

有効/無効設定

Checks for this warning class are disabled by default, and require strict C# analysis mode which is also disabled by default. To enable the checks, make the following changes to the project configuration file.

CSHARP_ANALYSIS_STRICT_MODE = Yes
WARNING_FILTER += allow class="clone Subclass of Non-clonable (C#)"

解決法

Check that Clone() is only redefined in classes that implement System.ICloneable. Check that the default implementation of Clone() is only used for classes that have explicitly declared to implement System.ICloneable.
