Attribute abstract
The OwnerThis is used on instance methods to declare ownership of disposable objects.
The following rules depict - based on the ownership status - when a disposable object must be disposed and when disposal must not be performed. Going by these rules will avoid situations where a resource is disposed although it is still being used and situations when a resource is never explicitly disposed, thus wasting system resources.
-
When used on an instance method / extension method:
... [OwnerThis] void MyObj(...) { ... } ... [OwnerThis] void MyObj(this IDisposable obj, ...) { ... } ...
The instance method takes ownership of the object that is (implicitly passed) to it as
this
, so the storage container from which the value ofthis
has originated is no longer responsible for disposal.
