Detailed Description

Base class to store a weak pointer to an internal DALi object.

The handle to the object can be accessed if the object exists, and such access is not reference counted. When the object is deleted, the weak pointer will be set to NULL, and any further attempt to access to a deleted object will return an empty handle.

Since:
4.0, DALi version 1.2.60

Constructor & Destructor Documentation

Dali::WeakHandleBase::WeakHandleBase ( )

Default constructor which provides an uninitialized Dali::WeakHandleBase.

Since:
4.0, DALi version 1.2.60
Dali::WeakHandleBase::WeakHandleBase ( Handle &  handle)

This constructor creates a weak handle of the DALi object.

Since:
4.0, DALi version 1.2.60
Parameters:
[in]handleA reference to the handle of the DALi object
Dali::WeakHandleBase::~WeakHandleBase ( )

Destructor to free resources.

Since:
4.0, DALi version 1.2.60
Dali::WeakHandleBase::WeakHandleBase ( const WeakHandleBase &  handle)

Copy constructor.

Since:
4.0, DALi version 1.2.60
Parameters:
[in]handleA reference to the copied WeakHandleBase

Member Function Documentation

Handle Dali::WeakHandleBase::GetBaseHandle ( ) 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
bool Dali::WeakHandleBase::operator!= ( const WeakHandleBase &  rhs) const

Inequality operator overload.

Since:
4.0, DALi version 1.2.60
Parameters:
[in]rhsA reference to the compared WeakHandleBase
Returns:
true if the handle points to the different DALi resources
WeakHandleBase& Dali::WeakHandleBase::operator= ( const WeakHandleBase &  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]rhsA reference to the copied WeakHandleBase
Returns:
A reference to this WeakHandleBase
bool Dali::WeakHandleBase::operator== ( const WeakHandleBase &  rhs) const

Equality operator overload.

Since:
4.0, DALi version 1.2.60
Parameters:
[in]rhsA reference to the compared WeakHandleBase
Returns:
true if the handle points to the same DALi resource, or if both are uninitialized
void Dali::WeakHandleBase::Reset ( )

Resets this weak handle to not point to any DALi object.

Since:
4.0, DALi version 1.2.60
