  • Method Details

    • getFeature

      EStructuralFeature getFeature()
      Return the mapped feature.
      Specified by:
      getFeature in interface IFeatureMapping
      Returns:
      the mapped feature.
    • getTypeMapping

      default ITypeMapping getTypeMapping()
      Specified by:
      getTypeMapping in interface IFeatureMapping
      Returns:
      The type mapping which is used for this feature mapping.
    • getField

      default org.eclipse.net4j.db.ddl.IDBField getField()
      Specified by:
      getField in interface IFeatureMapping
      Returns:
      The value field which is associated with this feature mapping.
    • getDBType

      default org.eclipse.net4j.db.DBType getDBType()
      Specified by:
      getDBType in interface IFeatureMapping
      Returns:
      The value type which is associated with this feature mapping.
    • getDBTables

      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, List<IStoreChunkReader.Chunk> chunks, 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.

    • queryXRefs

      boolean queryXRefs(IDBStoreAccessor accessor, String mainTableName, String mainTableWhere, IStoreAccessor.QueryXRefsContext context, String idString)
      Retrieve cross-references from DB.
