Interface AssignmentStrategy

All Known Implementing Classes:

SelectorAssignmentStrategy

public interface AssignmentStrategy

Given the query result and the filelist, the AssignmentStrategy assign the copies of the files to the different targets (single nodes, or groups).

This is no easy problem, and is in the end a good part of the Policy. That is why we decided to create directly an interface for this part of the policy: to be able to play with different alternatives.

Also, in different cases it might be easier to find an optimal solution. In that case, different implementation might be used.
