State: final Type: Specification
The Binary Uno runtime currently returns no mapping, in case of a identity request "A" -> "A". The Uno runtime should return an indentity-mapping in case of an identity request.
Rationale
Generic functions, e.g. as in cppuhelper/bootstrap.cxx, currently need to care about the identity of environments, this is cumbersome and leads to duplicate code.
API
The Uno runtime function
void SAL_CALL uno_getMapping(uno_Mapping ** ppMapping, uno_Environment * pFrom, uno_Environment * pTo, rtl_uString * pAddPurpose) SAL_THROW_EXTERN_C();
returns an identity-mapping, in case pFrom == pTo, instead of NULL.
