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 object was created. The modify property represents the point of time when the Document was last modified 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.

    • getData

      public Map<String,List<Object>> getData()
      returns the data object part of the Entity represented by a java.util.Map

      Data is loaded eager because it is read in any case by the DocumentService.

      Returns:
      Map

    • setData

      public void setData(Map<String,List<Object>> itemCol)
      sets a data object for this Entity.

      Note: the modified timestamp will be updated automatically to the current point of time (see setModified) independent from the value of the item $modified. The item $modified will be updated by the DocumentService on read.

      Parameters:
      data -
      Throws:
      InvalidAccessException - if $modified is missing
