## Methods

| Method | Description |
| --- | --- |
| [operator!=](./operator!=/)(std::nullptr_t) const | Checks if referenced object is not null. |
| [operator!=](./operator!=/)(const WeakReference\<T\>\&) const | Compares referenced object to another instance [WeakReference](../weakreference/) class. |
| [operator==](./operator==/)(std::nullptr_t) const | Checks if referenced object is null. |
| [operator==](./operator==/)(const WeakReference\<T\>\&) const | Compares referenced object to another instance [WeakReference](../weakreference/) class. |
| [reset](./reset/)() |  |
| [SetTarget](./settarget/)(const SmartPtr\<T\>\&) | Sets the object (the target) referenced by the current [WeakReference](../weakreference/) object. |
| [TryGetTarget](./trygettarget/)(const SmartPtr\<T\>\&) const | Gets the object (the target) referenced by the current [WeakReference](../weakreference/) object. |
| [WeakReference](./weakreference/)() | Default constructor. |
| [WeakReference](./weakreference/)(std::nullptr_t) | Constructor from nullptr. |
| [WeakReference](./weakreference/)(const SmartPtr\<T\>\&) | Initializes a new instance of the [WeakReference](../weakreference/) class, referencing the specified object. |
