Interface IInconsistencyResolver<T>

All Known Implementing Classes:

ChainedResolver, TimeBasedInconsistencyResolver, VectorClockInconsistencyResolver

public interface IInconsistencyResolver<T>

A method for resolving inconsistent object values into a single value. Applications can implement this to provide a method for reconciling conflicts that cannot be resolved simply by the version information.

Method Summary

java.util.List<T>

resolveConflicts(java.util.List<T> items) Take two different versions of an object and combine them into a single version of the object Implementations must maintain the contract that resolveConflict([null, null]) == null if t != null, then resolveConflict([null, t]) == resolveConflict([t, null]) == t

Method Detail

resolveConflicts

java.util.List<T> resolveConflicts(java.util.List<T> items)

Take two different versions of an object and combine them into a single version of the object Implementations must maintain the contract that

1. resolveConflict([null, null]) == null
2. if t != null, then resolveConflict([null, t]) == resolveConflict([t, null]) == t

Parameters:

items - The items to be resolved

The united object
