Evolution

Previously, only files consisting of relevant MongoDB imports were processed further for analysing.
Support has been evolved to process a file when it does not contain MongoDB import but makes use of its methods (APIs). Assumption here is file makes use of same namespace as used in the file containing MongoDB imports.

Limitations

Connection, database and collection names are resolved as known objects only in the following situations:
- Name is hardcoded
- Name is defined in the variable in the local method
- Name is defined in the config files
Only files consisting of relevant MongoDB imports are processed further for analysing. In a case, where a file uses reference of another file / namespace which in turn uses relevant import, then file will not be analysed.
