## Detailed Description

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

## Constructor & Destructor Documentation

## ◆ Master()

template<class ObjectType , class ReferenceCountingType = ReferenceCountedObject>

WeakReference< ObjectType, ReferenceCountingType >::Master::Master | ( |  | ) |
| default

## ◆ ~Master()

template<class ObjectType , class ReferenceCountingType = ReferenceCountedObject>

WeakReference< ObjectType, ReferenceCountingType >::Master::~Master | ( |  | ) |
| noexcept

References ReferenceCountedObjectPtr< ObjectType >::get(), and jassert.

## Member Function Documentation

## ◆ getSharedPointer()

template<class ObjectType , class ReferenceCountingType = ReferenceCountedObject>

SharedRef WeakReference< ObjectType, ReferenceCountingType >::Master::getSharedPointer | ( | ObjectType * | object | ) |

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

References ReferenceCountedObjectPtr< ObjectType >::get(), and jassert.

## ◆ clear()

template<class ObjectType , class ReferenceCountingType = ReferenceCountedObject>

void 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 WeakReference< ObjectType, ReferenceCountingType >::Master::getNumActiveWeakReferences | ( |  | ) | const
| noexcept

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