org.eclipse.persistence.mappings.MultitenantPrimaryKeyMapping
All Implemented Interfaces:
Serializable, Cloneable
public class MultitenantPrimaryKeyMapping extends AbstractColumnMapping
Purpose: Maps a multitenant property to the corresponding database field type. The list of field types that are supported by EclipseLink's direct to field mapping is dependent on the relational database being used.

    • buildBackupClone

      public void buildBackupClone(Object clone, Object backup, org.eclipse.persistence.internal.sessions.UnitOfWorkImpl unitOfWork)
      INTERNAL: Clone the attribute from the clone and assign it to the backup. This is an override from DatabaseMapping and must be implemented.
      Specified by:
      buildBackupClone in class DatabaseMapping

    • buildClone

      public void buildClone(Object original, org.eclipse.persistence.internal.identitymaps.CacheKey cacheKey, Object clone, Integer refreshCascade, org.eclipse.persistence.internal.sessions.AbstractSession cloningSession)
      INTERNAL: Clone the attribute from the original and assign it to the clone. This is an override from DatabaseMapping and must be implemented.
      Specified by:
      buildClone in class DatabaseMapping

    • buildCloneFromRow

      public void buildCloneFromRow(org.eclipse.persistence.internal.sessions.AbstractRecord databaseRow, org.eclipse.persistence.internal.queries.JoinedAttributeManager joinManager, Object clone, org.eclipse.persistence.internal.identitymaps.CacheKey sharedCacheKey, ObjectBuildingQuery sourceQuery, org.eclipse.persistence.internal.sessions.UnitOfWorkImpl unitOfWork, org.eclipse.persistence.internal.sessions.AbstractSession executionSession)
      INTERNAL: Extract value from the row and set the attribute to this value in the working copy clone. In order to bypass the shared cache when in transaction a UnitOfWork must be able to populate working copies directly from the row.
      Specified by:
      buildCloneFromRow in class DatabaseMapping

    • compareForChange

      INTERNAL: Compare the clone and backup clone values and return a change record if the value changed. This is an override from DatabaseMapping and must be implemented.
      Specified by:
      compareForChange in class DatabaseMapping
      Returns:
      prototype.changeset.ChangeRecord

      DescriptorException

    • isCloningRequired

      public boolean isCloningRequired()
