Communicating between Flex Project and Customed Library

Can we access the variabl开发者_如何学Ces of main project in the customized library or vice-versa ?

The Main project can access the Library project (add it via the Main project's Properties>Flex Build Path>Add SWC), but the library does not access the Main project files directly.

An alternative is to have a third Common library project that contains classes that will be common to both the Main project and the Library project in question.
