    • isGeneratedPackageEmulationEnabled

      boolean isGeneratedPackageEmulationEnabled()

    • setGeneratedPackageEmulationEnabled

      void setGeneratedPackageEmulationEnabled(boolean generatedPackageEmulationEnabled)

    • getCollectionLoadingPolicy

      CDOCollectionLoadingPolicy getCollectionLoadingPolicy()
      The collection loading policy of this session controls how a list gets populated. By default, when an object is fetched, all its elements are filled with the proper values.

      This could be time-consuming, especially if the reference list does not need to be accessed. In CDO it is possible to partially load collections. The default list implementation that is shipped with CDO makes a distinction between the two following situations:

      1. How many CDOIDs to fill when an object is loaded for the first time;
      2. Which elements to fill with CDOIDs when the accessed element is not yet filled.
      Example:

      CDOUtil.createCollectionLoadingPolicy(initialElements, subsequentElements);

      The user can also provide its own implementation of the CDOCollectionLoadingPolicy interface.

    • setCollectionLoadingPolicy

      void setCollectionLoadingPolicy(CDOCollectionLoadingPolicy policy)
      Sets the collection loading to be used by this session.

    • getLobCache

      CDOLobStore getLobCache()
      Returns the large object cache currently being used by this session.
      Since:
      4.0

    • setLobCache

      void setLobCache(CDOLobStore lobCache)
      Sets the large object cache to be used by this session.

      4.0

    • getPermissionUpdater

      CDOPermissionUpdater getPermissionUpdater()
      Returns the permission updater currently being used by this session.
      Since:
      4.3

    • setPermissionUpdater

      void setPermissionUpdater(CDOPermissionUpdater permissionUpdater)
      Sets the permission updater to be used by this session.
      Since:
      4.3

    • isDelegableViewLockEnabled

      boolean isDelegableViewLockEnabled()
      Since:
      4.5

    • setDelegableViewLockEnabled

      void setDelegableViewLockEnabled(boolean delegableViewLockEnabled)
      This method is useful, for example, if EMF adapters call Display.syncExec() in response to CDO notifications. In these cases a DelegableReentrantLock can be injected into the new view, which does not deadlock when both CDO's invalidation thread and the display thread acquire the view lock.
