Member Function Documentation

◆ AssignReferenceController()

template<ESPMode Mode>
void SharedPointerInternals::FWeakReferencer< Mode >::AssignReferenceController ( TReferenceControllerBase< Mode > * NewReferenceController)
inlineprivate

Assigns a new reference controller to this counter object, first adding a reference to it, then releasing the previous object.

Definition at line 759 of file SharedPointerInternals.h.

◆ IsValid()

template<ESPMode Mode>
FORCEINLINE const bool SharedPointerInternals::FWeakReferencer< Mode >::IsValid ( ) const
inline

Tests to see whether or not this weak counter contains a valid reference

Returns
True if reference is valid

Definition at line 750 of file SharedPointerInternals.h.

◆ operator=() [1/3]

template<ESPMode Mode>
FORCEINLINE FWeakReferencer & SharedPointerInternals::FWeakReferencer< Mode >::operator= ( FSharedReferencer< Mode > const & InSharedReference)
inline

Assignment operator from a shared reference counter. If this counter was previously referencing an object, that reference will be released.

Definition at line 738 of file SharedPointerInternals.h.

◆ operator=() [2/3]

template<ESPMode Mode>
FORCEINLINE FWeakReferencer & SharedPointerInternals::FWeakReferencer< Mode >::operator= ( FWeakReferencer< Mode > && InWeakReference)
inline

Assignment operator from an rvalue weak referencer object. If this counter was previously referencing an object, that reference will be released.

Definition at line 723 of file SharedPointerInternals.h.

◆ operator=() [3/3]

template<ESPMode Mode>
FORCEINLINE FWeakReferencer & SharedPointerInternals::FWeakReferencer< Mode >::operator= ( FWeakReferencer< Mode > const & InWeakReference)
inline

Assignment operator from a weak referencer object. If this counter was previously referencing an object, that reference will be released.
