The Conflicts class represents a list of conflicts. When conflicts are detected between changes made by a client and those made on the server, a Conflict object is created for each item which contains both the client and server versions of the data involved in that item at any given time.

You cannot commit any changes until all conflicts are resolved. At that point, the DataService.commit() method will call remove all of these conflicts. If you attempt to resolve a Conflict which was already resolved, an error is thrown.

An instance of this class can be accessed from the DataService.conflicts property.

Because this class implements IList it can be used with an ArrayCollection.list property, allowing it to participate as a data source for user interface controls and data binding.

This is a convenience method that iterates all of the conflicts within this list and invokes the Conflict.acceptClient() method. Once completed this method will clear all of the conflicts in the list. Calling this method will requeue each local change and update all property values such that a subsequent call to DataService.commit() should succeed, allowing these changes to override the current ones.
