Hi guys,

After discussing with Manik, seems like a memory based eviction policy might be helpful in certain scenarios.
I'm thinking to implement it in two steps:
1) define a more general points based eviction policy. The basic idea is that for each object in the cache the user can 'plugglablly' define a number of points(the memory is just a particularization, i.e. the number of points for an object is represented by its size). When the sum of points for all objects present in the cache is reached, the policy will trigger the eviction: it will start removing nodes based on a defined strategy (LRU, MRU, MFU etc) until the  number of points goes bellow the threshold. I think this points approach will add a bit of flexibility in the way the eviction might be used.
2) The second step is to supply an implementation in which the points represent memory units

Any thoughts?

Cheers,
Mircea
