writeRecord

protected void writeRecord(String recId,

                           XMLDocReader docReader,
                           DcsDataRecord dcsDataRecord)
                    throws RecordUpdateException,
                           Exception

Convenience method for RepositoryServices calls that have the docReader handy, calls writeRecord after computing required params.

Parameters:

recId - metadata record id

recordXml - metadata record as xml string

docReader - docReader for metadata

dcsDataRecord - dcsDataRecord for metadata

Throws:

RecordUpdateException - if record cannot be written to index

Exception - NOT YET DOCUMENTED

writeRecord

protected void writeRecord(String recordXml,
                           String xmlFormat,
                           String collection,
                           String id,
                           DcsDataRecord dcsDataRecord)
                    throws RecordUpdateException,
                           Exception

Writes provided metadata to the index and to other registered repositories, such as the NDR.

First try to write to the external repository. This attempt may fail before the record has been indexed the first time, if a RepositoryWriterPlugin required the index (as the NDR plugin does). In this case, a syncError is registered in the index.

Parameters:

recordXml - metadata record as xml string

xmlFormat - format of metadata

collection - collection key of metadata record (e.g., "dcc")

id - metadata record id

dcsDataRecord - dcsDataRecord for metadata

Throws:

RecordUpdateException - if record cannot be written to index

Exception - NOT YET DOCUMENTED

deleteRecord

protected boolean deleteRecord(String recId,
                               DcsDataRecord dcsDataRecord)
                        throws Exception

Delete a record from the repository.

Current plugin exception policy: If there is a pluginError, the record is NOT deleted, but instead it is re-indexed as a sync-error.

Parameters:

recId - NOT YET DOCUMENTED

dcsDataRecord - NOT YET DOCUMENTED

Returns:

NOT YET DOCUMENTED

Throws:

Exception - NOT YET DOCUMENTED

deleteCollection

protected boolean deleteCollection(CollectionConfig config)
