ObjectClassOps Interface

public interface ObjectClassOps

    extends Serializable

This interface represents a service for ObjectClass CRUD operations. It is used to manage ObjectClasses as well as their PropertyDefinitions and PropertyChoices. Each ObjectClass may contain 0 to many PropertyDefinitions and each PropertyDefinition may contain 0 to many PropertyChoices.

Each repository has specific validation rules that the manager will delegate to. If a repository considers an attempted operation invalid, it will throw a RepositoryException. The rules for the manager are defined below.

All ObjectClasses, PropertyDefinitions and PropertyChoices are uniquely identified through their ID. The ID must contain both the repositoryName and the uid, unless the operation is a create then the uid should be null.

This interface does not support inheritance, or nested ObjectClasses. If the underlying repository does, then all super PropertyDefinitions will be retrieved with the specified ObjectClass.

Each operation may only occur against one repository at a time. Therefore, all IDs in a single operation must all have the same repository name.

For additional rules see com.bea.content.PropertyDefinition.
