Detailed Description

A dynamic type dispatcher.

The type dispatcher can be used to pass objects of arbitrary types from one component to another. With regard to the library, the type dispatcher can be used to extract attribute values.

The dynamic type dispatcher can be initialized in run time and, therefore, can support different types, depending on runtime conditions. Each supported type is associated with a functional object that will be called when an object of the type is dispatched.

boost::dynamic_type_dispatcher::dynamic_type_dispatcher ( dynamic_type_dispatcher const &  that )

inline

Copy constructor.

Member Function Documentation

boost::type_dispatcher::BOOST_DEFAULTED_FUNCTION ( type_dispatcher(type_dispatcher const &that)  , :m_get_callback_impl(that.m_get_callback_impl){}    )

inlineprotectedinherited

The method requests a callback for the value of type T.

Returns

The type-specific callback or an empty value, if the type is not supported

inline

Copy assignment.

template<typename T , typename VisitorT >

void boost::dynamic_type_dispatcher::register_type ( VisitorT const &  visitor )

inline

The method registers a new type.

Parameters

visitor

Function object that will be associated with the type T
