Update Documents in a Repository

The following table lists fetch actions that update documents in a repository.

Action	Description	Method to override
/action=fetch&fetchaction=Delete	Delete specified documents from the repository.	Remove
/action=fetch&fetchaction=Insert	Insert a document or documents into a repository.	Insert
/action=fetch&fetchaction=Update	Update the metadata for specified documents in the repository.	Update
/action=fetch&fetchaction=Hold	Apply a legal hold to the specified documents in the repository.	Hold
/action=fetch&fetchaction=ReleaseHold	Remove a legal hold from the specified documents in the repository.

Like the Collect fetch action (see Retrieve Documents from a Repository), these actions are passed a collection of DocInfo objects, each of which contains an identifier. Like the Collect fetch action, success or failed must be called on each object to indicate whether the document was processed successfully.

The DocInfo objects passed to Delete, Hold, ReleaseHold and Update contain identifiers of documents that exist in the repository. The DocInfo objects passed to Update also contain the metadata to set in the repository.

The DocInfo objects passed to Insert contain document content and metadata, including information about where in the repository the new file should be inserted. This information could be part of the reference, identifier, or metadata. It is up to you to specify what information is required.

If you want to use the Insert action to insert documents that contain only metadata, you must override the features method on ConnectorBase to enable insertion of metadata-only documents (this is the only case that this is necessary):

       public int features()
       {
	   int features = super.features();
	   features |= Features.InsertAllowMetadataOnly;
	   return features;
       }
