* This module makes its instances non-copyable, by explicitely disabling its initialize_copy method.
|
|

|
|
* To create a non-copyable class, simply include the SFML::NonCopyable module.
|
|
*
|

* Usage example:
|
|

|
|
* class MyNonCopyableClass

* Deciding whether the instances of a class can be copied or not is a very important design choice. You are strongly
|
|
* encouraged to think about it before writing a class, and to use SFML::NonCopyable when necessary to prevent many
|
|
* potential future errors when using it. This is also a very important indication to users of your class.
