Request for a Many-to-Many BidiMap
----------------------------------
Key: COLLECTIONS-356
URL: https://issues.apache.org/jira/browse/COLLECTIONS-356
Project: Commons Collections
Issue Type: New Feature
Components: Collection
Reporter: Franz Wong
Priority: Minor
Currently, BidiMap supports one to one relationship. However, in real life,
there are many many-to-many relationships. Take an example of student and
course. One student can take many courses while one course contain many
students. It would be useful to have a class to manipulate such situation.
The work around currently is using 2 hash maps.
