Classes
class	juce::WeakReference< ObjectType, ReferenceCountingType >
	This class acts as a pointer which will automatically become null if the object to which it points is deleted. More...
class	juce::WeakReference< ObjectType, ReferenceCountingType >::Master
	This class is embedded inside an object to which you want to attach WeakReference pointers. More...
class	juce::WeakReference< ObjectType, ReferenceCountingType >::SharedPointer
	This class is used internally by the WeakReference class - don't use it directly in your code! More...

Class

)

Value:

struct WeakRefMaster  : public juce::WeakReference<Class>::Master { ~WeakRefMaster() { this->clear(); } }; \
    WeakRefMaster masterReference; \
    friend class juce::WeakReference<Class>; \

Macro to easily allow a class to be made weak-referenceable.

This can be inserted in a class definition to add the requisite weak-ref boilerplate to that class. e.g.

class MyObject
{
public:
    MyObject();
    ~MyObject();

private:
    JUCE_DECLARE_WEAK_REFERENCEABLE (MyObject)
};
