Detailed Description

template<typename T>
class adobe::promote< T >

Details:

Type promotion is the operation of converting a value into another type without any loss of resolution as to the original value (lossless conversion). For example, type promotion is implicit in the language when one sets a double from a long. Further explicit type promotions are possible for user-defined types through template specializations of this struct. See adobe::value_t for a type that utilizes adobe::promote.

Note:

char is not specified to promote to wchar_t as standard behavior. Without knowing the source or destination character encodings there is not enough information to do this type promotion correctly.
