Detailed Description

template<typename T>
class boost::attributes::attribute_value_impl< T >

Basic attribute value implementation class.

This class can be used as a boilerplate for simple attribute values. The class implements all needed interfaces of attribute values and allows to store a single value of the type specified as a template parameter. The stored value can be dispatched with type dispatching mechanism.

Member Typedef Documentation

template<typename T>

typedef T boost::attributes::attribute_value_impl< T >::value_type

Value type.

Constructor & Destructor Documentation

template<typename T>

boost::attributes::attribute_value_impl< T >::attribute_value_impl ( value_type const &  v )

inlineexplicit

Constructor with initialization of the stored value.

template<typename T>

boost::attributes::attribute_value_impl< T >::attribute_value_impl ( BOOST_RV_REF(value_type)  v )

inlineexplicit

Constructor with initialization of the stored value.

Member Function Documentation

virtual intrusive_ptr< impl > boost::attribute_value::impl::detach_from_thread ( )

inlinevirtualinherited

The method is called when the attribute value is passed to another thread (e.g.

in case of asynchronous logging). The value should ensure it properly owns all thread-specific data.

Returns

An actual pointer to the attribute value. It may either point to this object or another. In the latter case the returned pointer replaces the pointer used by caller to invoke this method and is considered to be a functional equivalent to the previous pointer.

Reimplemented in boost::sources::aux::severity_level< LevelT >::impl, and boost::attributes::current_thread_id::impl.

Referenced by boost::attribute_value::detach_from_thread().

template<typename T>

virtual bool boost::attributes::attribute_value_impl< T >::dispatch ( type_dispatcher &  dispatcher )

inlinevirtual

Attribute value dispatching method.

Parameters

dispatcher

The dispatcher that receives the stored value

Returns

true if the value has been dispatched, false otherwise

Implements boost::attribute_value::impl.

template<typename T>

value_type const& boost::attributes::attribute_value_impl< T >::get ( ) const

inline

Returns

Reference to the contained value.

template<typename T>

type_info_wrapper boost::attributes::attribute_value_impl< T >::get_type ( ) const

inlinevirtual

Returns

The attribute value type

Reimplemented from boost::attribute_value::impl.

virtual attribute_value boost::attribute_value::impl::get_value ( )

inlinevirtualinherited

Returns

The attribute value that refers to self implementation.

Implements boost::attribute::impl.
