  Microsoft.Office.RecordsManagement.RecordsRepository.EcmDocumentRouter

Namespace:  Microsoft.Office.RecordsManagement.RecordsRepository
Assembly:  Microsoft.Office.Policy (in Microsoft.Office.Policy.dll)

Syntax

'Declaration
Public Class EcmDocumentRouter
'Usage
Dim instance As EcmDocumentRouter
public class EcmDocumentRouter

Remarks

The content organizer feature enables content stewards to configure their sites so that there is a single point of content creation and submission and so that content is automatically saved to the appropriate location based on the metadata of the document. Use the EcmDocumentRouterRule to specify the final location for documents based on their content type and conditions. The content organizer for a specified site uses the RoutingRuleCollection property to store all of the rules defined for a EcmDocumentRoutingWeb object.

Initialize a new instance of the EcmDocumentRouter class by using the Router property of an EcmDocumentRoutingWeb. The EcmDocumentRouter class also provides an API (SaveFileToFinalLocation(EcmDocumentRoutingWeb, SPFolder, Stream, String, String, Hashtable, SPUser, Boolean, String)) to override the pre-configured location and save the document to a different location.

The following code includes a sample custom router that inspects the content of a text file that is being saved for sensitive information, and a class that you can use to reorganize documents on a site based on new content organizer rules.
