Detailed Description
template<class T>
class WeakConstPointerTo< T >
A WeakConstPointerTo is similar to a WeakPointerTo, except it keeps a const pointer to the thing, that will be cleared to NULL when the thing deleted.
Definition at line 86 of file weakPointerTo.h.
Member Function Documentation
◆ get_orig()
template<class T >
|
inline |
Returns the original pointer value, even if the object has since been deleted.
Definition at line 430 of file weakPointerTo.I.
◆ lock()
template<class T >
|
inline |
A thread-safe way to access the underlying pointer; will silently return null if the underlying pointer was deleted or null.
- Since
- 1.10.0
Definition at line 407 of file weakPointerTo.I.
◆ operator const T *()
template<class T >
|
inlineexplicit |
We also have the typecast operator to automatically convert WeakConstPointerTo's to the required kind of actual pointer.
This introduces ambiguities which the compiler will resolve one way or the other, but we don't care which way it goes because either will be correct.
Definition at line 394 of file weakPointerTo.I.
◆ p()
template<class T >
|
inline |
Returns an ordinary pointer instead of a WeakConstPointerTo.
Useful to work around compiler problems, particularly for implicit upcasts.
