Detailed Description

template<typename T>
class dds::core::WeakReference< T >

The WeakReference class enables you to maintain a weak reference to a DDS reference type.

The existence of a weak link will not prevent the garbage collection of the reference type.

Constructor & Destructor Documentation

WeakReference() [1/2]

template<typename T >

dds::core::WeakReference< T >::WeakReference

(

)

Creates a weak reference without an referenced dds object.

WeakReference() [2/2]

template<typename T >

dds::core::WeakReference< T >::WeakReference

(

const T &

t

)

Creates a weak reference for the reference type passed as argument.

Template Parameters

t	dds object the new weak reference will refer to

Member Function Documentation

expired()

template<typename T >

bool dds::core::WeakReference< T >::expired

(

)

Checks whether the underlying reference has been deleted.

Returns

true if the underlying reference has expired, false otherwise

lock()

template<typename T >

T dds::core::WeakReference< T >::lock

(

)

Gives access to the underlying shared reference.

If the reference has expired the returned object will be referencing 'dds::core::null'.

Returns

referenced dds object
