Detailed Description

template<typename Storage, typename ObjectArgStorage = Storage>
class cpp::typeerasure::Field< Storage, ObjectArgStorage >

Stores a type erased member object pointer.

Field class can store pointers to member objects of any class and type, suitable to be stored in an homogeneous context (Such as a vector). It also provides methods to access the type-erased pointer and access the member object of a given object

Template Parameters

Storage	Storage for the member function pointer
ObjectArgStorage	Storage for the object argument of a get() call

template<typename Storage , typename ObjectArgStorage = Storage>

template<typename Object >

decltype(auto) cpp::typeerasure::Field< Storage, ObjectArgStorage >::get ( const Object & object ) const

inline

Returns the value of the member object of a given object.

This function accesses to the member object referenced by the Field object on a given object. The behavior is undefined if the given object is not of the same class the stored member object pointer belongs to. Also, the behavior is undefined if the Field object is empty.

Returns: A type-erased reference to the member object in the given object

template<typename Storage , typename ObjectArgStorage = Storage>

template<typename Object >

decltype(auto) cpp::typeerasure::Field< Storage, ObjectArgStorage >::get ( Object & object ) const

inline

Returns the value of the member object of a given object.

This function accesses to the member object referenced by the Field object on a given object. The behavior is undefined if the given object is not of the same class the stored member object pointer belongs to. Also, the behavior is undefined if the Field object is empty.

Returns: A type-erased reference to the member object in the given object Returns a reference to the member object pointer stored by the Field object

The behavior is undefined if the Field object is empty

Template Parameters
