Detailed Description
template<class T>
class Dali::WeakHandle< T >
Weak handle for the given type of DALi object.
- Since:
- 4.0, DALi version 1.2.60
- See also:
- WeakHandleBase
Constructor & Destructor Documentation
template<class T >
| Dali::WeakHandle< T >::WeakHandle | ( | ) |
Default constructor which provides an uninitialized Dali::WeakHandleBase.
- Since:
- 4.0, DALi version 1.2.60
template<class T >
| Dali::WeakHandle< T >::WeakHandle | ( | T & | handle | ) |
This constructor creates a weak handle of the DALi object.
- Since:
- 4.0, DALi version 1.2.60
- Parameters:
-
[in] handle A reference to the handle of the DALi object
template<class T >
| Dali::WeakHandle< T >::~WeakHandle | ( | ) |
Destructor to free resources.
- Since:
- 4.0, DALi version 1.2.60
template<class T >
| Dali::WeakHandle< T >::WeakHandle | ( | const WeakHandle< T > & | handle | ) |
Copy constructor.
- Since:
- 4.0, DALi version 1.2.60
- Parameters:
-
[in] handle A reference to the copied WeakHandleBase
Member Function Documentation
template<class T >
| T Dali::WeakHandle< T >::GetHandle | ( | ) | const |
Gets the handle to the DALi object.
- Since:
- 4.0, DALi version 1.2.60
- Returns:
- The handle of the DALi object pointed by this WeakHandleBase or an empty handle if the DALi object doesn't exist
template<class T >
| bool Dali::WeakHandle< T >::operator!= | ( | const WeakHandle< T > & | rhs | ) | const |
Inequality operator overload.
- Since:
- 4.0, DALi version 1.2.60
- Parameters:
-
[in] rhs A reference to the compared WeakHandleBase
- Returns:
- true if the handle points to the different DALi resources
template<class T >
| WeakHandle& Dali::WeakHandle< T >::operator= | ( | const WeakHandle< T > & | rhs | ) |
Assignment operator.
It makes this WeakHandleBase point to the same internal DALi object as the copied WeakHandleBase
- Since:
- 4.0, DALi version 1.2.60
- Parameters:
-
[in] rhs A reference to the copied WeakHandleBase
- Returns:
- A reference to this WeakHandleBase
template<class T >
| bool Dali::WeakHandle< T >::operator== | ( | const WeakHandle< T > & | rhs | ) | const |
Equality operator overload.
- Since:
- 4.0, DALi version 1.2.60
- Parameters:
-
[in] rhs A reference to the compared WeakHandleBase
- Returns:
- true if the handle points to the same DALi resource, or if both are uninitialized
