All Implemented Interfaces:

SchemaElement
```
public final class ObjectClass
extends Object
```
This class defines a data structure for storing and interacting with an objectclass, which contains a collection of attributes that must and/or may be present in an entry with that objectclass.
Where ordered sets of names, attribute types, or extra properties are provided, the ordering will be preserved when the associated fields are accessed via their getters or via the Object.toString() methods.
