AbstractIndexableObject (DSpace Kernel :: API and Implementation 7.6.1 API)

java.lang.Object
- org.dspace.discovery.indexobject.AbstractIndexableObject<T,PK>

Type Parameters:

T - Refers to the underlying entity that is linked to this object

PK - The type of ID that this entity uses

All Implemented Interfaces:

IndexableObject<T,PK>

Direct Known Subclasses:

IndexableClaimedTask, IndexableDSpaceObject, IndexableInProgressSubmission, IndexableMetadataField, IndexablePoolTask
```
public abstract class AbstractIndexableObject<T extends ReloadableEntity<PK>,PK extends Serializable>
extends Object
implements IndexableObject<T,PK>
```
This class exists in order to provide a default implementation for the equals and hashCode methods. Since IndexableObjects can be made multiple times for the same underlying object, we needed more finely-tuned equals(java.lang.Object) and hashCode() methods. We're simply checking that the underlying objects are equal and returning the hash-code for the underlying object. This way, we'll always get a proper result when calling equals(java.lang.Object) or hashCode() on an IndexableObject because it'll depend on the underlying object.
