Jeff Eastman updated MAHOUT-65:
-------------------------------
Assignee: Jeff Eastman
Affects Version/s: 0.1
Status: Patch Available (was: Open)
Here's a patch that re-implements the previous simple scheme for supporting
Vector accessing via a user-settable Map of index bindings. In this patch, the
map itself is not serialized with the vector. In preparation for changing the
serialization to use Json I moved the JsonVectorAdapter from Dirichlet (where
it was not actually used).
This implementation could be generalized by making the map hold a richer record
containing other properties of the index.
