juce::WeakReference< ObjectType, ReferenceCountingType >::Master Class Reference

Detailed Description

template<class ObjectType, class ReferenceCountingType = ReferenceCountedObject>
class juce::WeakReference< ObjectType, ReferenceCountingType >::Master

This class is embedded inside an object to which you want to attach WeakReference pointers.

See the WeakReference class notes for an example of how to use this class.

Public Member Functions
	Master ()=default
	~Master () noexcept
SharedRef	getSharedPointer (ObjectType *object)
	The first call to this method will create an internal object that is shared by all weak references to the object.
void	clear () noexcept
	The object that owns this master pointer should call this before it gets destroyed, to zero all the references to this object that may be out there.
int	getNumActiveWeakReferences () const noexcept
	Returns the number of WeakReferences that are out there pointing to this object.

)

The first call to this method will create an internal object that is shared by all weak references to the object.

clear()

template<class ObjectType, class ReferenceCountingType = ReferenceCountedObject>

void juce::WeakReference< ObjectType, ReferenceCountingType >::Master::clear ( )

noexcept

The object that owns this master pointer should call this before it gets destroyed, to zero all the references to this object that may be out there.

See the WeakReference class notes for an example of how to do this.

getNumActiveWeakReferences()

template<class ObjectType, class ReferenceCountingType = ReferenceCountedObject>

int juce::WeakReference< ObjectType, ReferenceCountingType >::Master::getNumActiveWeakReferences ( ) const

noexcept

Returns the number of WeakReferences that are out there pointing to this object.
