Interface IObjectDerivedDataContext

All Known Implementing Classes:
AbstractExportContext, BasicObjectContext, CleanResourcesContext, CmiDerivedDataContext, ExportBlobContext, ExportObjectContext, ExtObjectUpdateContext, FormExtContext, ImportDataContext, LanguageCheckObjectContext, MarkerCleanerContext, MarkerReindexContext, ModelCheckObjectContext, ModelUpdaterContext, NavigatorOrderContext, OperationContext, PartBasedObjectContext, TextSearchIndexingContext
public interface IObjectDerivedDataContext
Derived data context for the object of the BM model stores the (transient) context being accumulated while processing DD-enabling business scenarios.
The context object is stored in memory only and it shouldn't be restored from some external persistent store explicitly. In case of emergency restart the new context with "rebuild all" strategy enabled should be created by the DD calculation mechanics.
The context and corresponding object are bound with internal BM id, as there are no scenarios when we have id changes in model and need to add DD incrementally. Full object DD rebuild is required in this case.

  • Method Details

    • getObjectId

      Object getObjectId()
      Gets the the object the context belongs to.
      Returns:
      The object, never null

    • getBmObjectId

      long getBmObjectId()
      Gets the identifier of the object the context belongs to.
      Returns:
      The identifier of the object.

    • getComputationCause

      Object getComputationCause()
      Gets the identifier of the session the context is being collected for. Used only for sync contexts.
      Returns:
      The identifier of the session.

    • getEClass

      org.eclipse.emf.ecore.EClass getEClass()
      Gets the EClass of the target object.
      Returns:
      The target object EClass.

    • getSegmentId

      String getSegmentId()
      Gets the derived data segment identifier this context is collected for.
      Returns:
      The unique identifier of the DD segment.

    • getTransactionHandle

      Object getTransactionHandle()
      Gets the associated transaction handle (if any).
      Returns:
      The associated transaction handle (if any). null otherwise.

    • getVersion

      long getVersion()
      Gets the current version of the context. The version is defined during the snapshotting of the context. The verison is used during the context merge process to update the base version.
      Returns:
      The version of the context.

    • isInactive

      boolean isInactive()
      Checks the inactivity status of this context
      Returns:
      True if context is inactive

    • setVersion

      void setVersion(long version)
      Sets an external version designator of the context. Called by the DD framework and should not be used by clients directly
      Parameters:
      version - A version to set

    • isFullRebuild

      boolean isFullRebuild()
      Checks if the full rebuild mode is set for the object.
      Returns:
      True if the full rebuild is required for the given top object.

    • mergeUpdates

      boolean mergeUpdates(IObjectDerivedDataContext context)
      Merges updates into the context. The base version of this context is being updated according to the verison of the provided context
      Parameters:
      context - The source of updates. Cannot be null.

    • setFullRebuild

      void setFullRebuild(boolean fullRebuild)
      Sets/resets the full rebuild designator for the context object DD.
      Parameters:
      fullRebuild - Full rebuild flag.

    • setTransactionHandle

      void setTransactionHandle(Object transactionHandle)
      Sets the transaction handle for this context.
      Parameters:
      The - transaction handle being associated with the context.

    • setInactive

      void setInactive(boolean inactive)
      Sets the inactive flag for a context
      Parameters:
      inactive - The inactivity state to set
