* 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.

|
|

|
|

|
* 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.
