CompareWithAIP (DSpace Replication Task Suite 7.1 API)

java.lang.Object
- org.dspace.curate.AbstractCurationTask
- - org.dspace.ctask.replicate.CompareWithAIP

All Implemented Interfaces:

org.dspace.curate.CurationTask
```
@Suspendable(invoked=INTERACTIVE)
public class CompareWithAIP
extends org.dspace.curate.AbstractCurationTask
```
CompareWithAIP task compares local repository values with the replica store values. It can perform 2 types of comparison: first, an 'integrity' audit which compares the checksums of the local and remote zipped AIPs; second, a 'count' or enumerative audit that verifies that all child objects of a local container have corresponding replicas in the remote store.
The reason it performs two checks is for performance purposes. We'd rather this task "fail quickly" by finding that a child object is missing from the remote store, than have it require stepping through each child object one-by-one and regenerate each AIP (for checksum verification) before the missing child is located.
This task is "suspendable" when invoked from the UI. This means that if you run an Audit from the UI, this task will return an immediate failure once a single object fails the audit. However, when run from the Command-Line this task will run to completion (i.e. even if an object fails it will continue processing to completion).
