struct ConstForwardingType
    : ForwardingType<t_TYPE>

Base Classes

Name Description

ForwardingType<t_TYPE> This template metafunction has a member Type computed such that, for a specified t_TYPE parameter, a function with argument of t_TYPE can be called efficiently from another function (e.g., a wrapper) by declaring the corresponding parameter of the other wrapper as 'typename ForwardingType<t_TYPE>::Type'. The Type member is computed to minimize the number of expensive copies while forwarding the arguments as faithfully as possible.

Name	Description
`ForwardingType<t_TYPE>`	This template metafunction has a member `Type` computed such that, for a specified `t_TYPE` parameter, a function with argument of `t_TYPE` can be called efficiently from another function (e.g., a wrapper) by declaring the corresponding parameter of the other wrapper as 'typename ForwardingType<t_TYPE>::Type'. The `Type` member is computed to minimize the number of expensive copies while forwarding the arguments as faithfully as possible.

Type Aliases

Name	Description
`TargetType`	The closest type used to "reconstitute" `t_TYPE` from `ForwardingType<t_TYPE>::Type`. This type may differ from `t_TYPE` through the addition of a reference.
`Type`	The type that should be used to forward `t_TYPE` through a chain of function calls.
