org.imixs.workflow.engine.jpa.Document

All Implemented Interfaces:

Serializable

@Entity
public class Document
extends Object
implements Serializable

This Document entity bean is a wrapper class for the org.imixs.workflow.ItemCollection which is used in all Imixs-Workflow Interfaces. The Document is used by the DocumentService to store ItemCollections into a database, using the Java Persistence API. Each Document is added into the Lucene index. A Document contains a universal unique ID to identify the Entity. Also the Document contains the following additional properties

• type
• created
• modified

The creation time represents the point of time where the Document was first saved by the DocumentService to the Database. The modify property represents the point of time where the Document was last saved by the DocumentService. The type property is used to categorize documents in a database. If an ItemCollection contains the attribute 'type' the value will be automatically mapped to the type property.

The data attribute is used to hold the ItemCollection data. It is mapped by a OR-Mapper to a large object (Lob). A Client should not work directly with an instance of the Document entity. It's recommended to use the DocumentService which acts as a session facade to manage instances of ItemCollection persisted in a database system.
