Detailed Description

Struct that stores the size of a polymorphic object, as well as pointers to functions to copy, move or destroy the object.

Inherit from this struct to add useful functions.

Public Types
template<class F >
using	required_function_t = typename required_function< F >::type
	A required function includes a void pointer to self, in addition to the arguments of `F`.

template<class F >
using	required_const_function_t = typename required_const_function< F >::type
	A required function includes a void pointer to self, in addition to the arguments of `F`.

template<class F , class VTable = BasicVTable>
using	optional_function_t = typename optional_function< F, VTable >::type
	An optional function includes a void pointer to self, the arguments of `F`, and an additional reference to the VTable, so that it can be implemented in terms of other functions.

template<class F , class VTable = BasicVTable>
using	optional_const_function_t = typename optional_const_function< F, VTable >::type
	An optional function includes a void pointer to self, the arguments of `F`, and an additional reference to the VTable, so that it can be implemented in terms of other functions.

Member Typedef Documentation

◆ required_function_t

using required_function_t = typename required_function<F>::type

A required function includes a void pointer to self, in addition to the arguments of F.

Definition at line 78 of file type-erasure.hpp.

◆ required_const_function_t

using required_const_function_t = typename required_const_function<F>::type

A required function includes a void pointer to self, in addition to the arguments of F.

For const-qualified member functions.

Definition at line 82 of file type-erasure.hpp.

◆ optional_function_t

using optional_function_t = typename optional_function<F, VTable>::type

An optional function includes a void pointer to self, the arguments of F, and an additional reference to the VTable, so that it can be implemented in terms of other functions.

Definition at line 87 of file type-erasure.hpp.

◆ optional_const_function_t

using optional_const_function_t = typename optional_const_function<F, VTable>::type

An optional function includes a void pointer to self, the arguments of F, and an additional reference to the VTable, so that it can be implemented in terms of other functions.

For const-qualified member functions.
