Detailed Description

A base class for an attribute value implementation.

All attribute value holders should derive from this interface.

Member Function Documentation

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

inlinevirtual

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().

virtual bool boost::attribute_value::impl::dispatch ( type_dispatcher &  dispatcher )

pure virtual

The method dispatches the value to the given object.

Parameters

dispatcher

The object that attempts to dispatch the stored value.

Returns

true if dispatcher was capable to consume the real attribute value type and false otherwise.

Implemented in boost::attributes::attribute_value_impl< T >, boost::attributes::attribute_value_impl< value_type >, boost::sources::aux::severity_level< LevelT >::impl, and boost::attributes::current_thread_id::impl.

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

virtual type_info_wrapper boost::attribute_value::impl::get_type ( ) const

inlinevirtual

Returns

The attribute value type

Reimplemented in boost::attributes::attribute_value_impl< T >, boost::attributes::attribute_value_impl< value_type >, and boost::attributes::current_thread_id::impl.

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

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

inlinevirtual

Returns

The attribute value that refers to self implementation.

Implements boost::attribute::impl.
