Method Detail

• getFeature

  EStructuralFeature getFeature()

  Return the mapped feature.

  Returns:

  the mapped feature.

• getDBTables

  java.util.Collection<org.eclipse.net4j.db.ddl.IDBTable> getDBTables()

  Returns all DB tables which are used by this feature.

  Returns:

  a collection of all tables of this feature.

• writeValues

  void writeValues​(IDBStoreAccessor accessor,
                   InternalCDORevision revision)

  Write a complete list of values to the database.

  Parameters:

  accessor - the accessor to use.

  revision - the revision containing the list to be written.

• readValues

  void readValues​(IDBStoreAccessor accessor,
                  InternalCDORevision revision,
                  int listChunk)

  Read the list size and the complete list or the first part of it.

  Parameters:

  accessor - the accessor to use.

  revision - the revision into which the list values should be read.

  listChunk - indicating the lazy loading behavior: CDORevision.UNCHUNKED means that the whole list should be read. Else, if listChunk >= 0, the list is filled with InternalCDOList.UNINITIALIZED and only the first listChunk values are read.

• readChunks

  void readChunks​(IDBStoreChunkReader dbStoreChunkReader,
                  java.util.List<IStoreChunkReader.Chunk> chunks,
                  java.lang.String where)

  Used to load-on-demand chunks of a list.

  Parameters:

  dbStoreChunkReader - the chunkReader to use

  chunks - the chunks to read

  where - the where-clause to use in order to read the chunks.

• objectDetached

  void objectDetached​(IDBStoreAccessor accessor,
                      CDOID id,
                      long revised)

  Hook with which a list mapping is notified that a containing object has been revised. Can be implemented in order to clean up lists of revised objects.

  Parameters:

  accessor - the accessor to use.

  id - the ID of the object which has been revised.

  revised - the timestamp at which the object was revised.

                     java.lang.String mainTableName,
                     java.lang.String mainTableWhere,
                     IStoreAccessor.QueryXRefsContext context,
                     java.lang.String idString)

  Retrieve cross-references from DB.
