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)
};
