• T_type The type of the reference.

Member Typedef Documentation

reference_type

template <typename T_type >

using sigc::limit_reference< T_type, true >::reference_type = typename std::remove_volatile_t<T_type>

Constructor & Destructor Documentation

limit_reference()

template <typename T_type >

sigc::limit_reference< T_type, true >::limit_reference ( reference_type &  target )

inline

Constructor.

Parameters

target

The reference to limit.

Member Function Documentation

invoke()

template <typename T_type >

T_type & sigc::limit_reference< T_type, true >::invoke ( ) const

inline

Retrieve the reference.

This is always a reference to the derived instance.

Returns

The reference.

visit()

template <typename T_type >

const trackable & sigc::limit_reference< T_type, true >::visit ( ) const

inline

Retrieve the entity to visit for visit_each().

Depending on the template specialization, this is either a derived reference, or sigc::trackable& if T_type derives from sigc::trackable.

Returns

The reference.
