public abstract class DatabaseMapping
extends java.lang.Object
implements java.lang.Cloneable, java.io.Serializable

Purpose: Defines how an attribute of an object maps to and from the database

Responsibilities:

• Define type of relationship (1:1/1:M/M:M/etc.)
• Define instance variable name and fields names required
• Define any additional properties (ownership, indirection, read only, etc.)
• Control building the value for the instance variable from the database row
• Control building the database fields from the object
• Control any pre/post updating/inserting/deleting required to maintain the relationship
• Merges object changes for unit of work.
• Clones objects for unit of work.
• cache computed information to optimize performance

                                                      org.eclipse.persistence.internal.sessions.UnitOfWorkImpl unitOfWork)

INTERNAL: Require for cloning, the part must be cloned.

buildClone

public abstract void buildClone(java.lang.Object original,
                                java.lang.Object clone,
                                org.eclipse.persistence.internal.sessions.UnitOfWorkImpl unitOfWork)

INTERNAL: Clone the attribute from the original and assign it to the clone.

buildCloneFromRow

public abstract void buildCloneFromRow(org.eclipse.persistence.internal.sessions.AbstractRecord databaseRow,
                                       org.eclipse.persistence.internal.queries.JoinedAttributeManager joinManager,

INTERNAL: A combination of readFromRowIntoObject and buildClone.

buildClone assumes the attribute value exists on the original and can simply be copied.

readFromRowIntoObject assumes that one is building an original.

Both of the above assumptions are false in this method, and actually attempts to do both at the same time.

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.

setIsJPAId

public void setIsJPAId()

INTERNAL: Flags that this mapping is part of a JPA id mapping. It should be temporary though, as the CMP3Policy should be able to figure things out on its own. The problem being that the JPA mapped superclass descriptors are not initialized and do not have a CMP3Policy set by default.

setIsLazy

public void setIsLazy(boolean isLazy)

Set if this mapping is lazy. This can be used for any mapping type to exclude it from the descriptor's default fetch group. This means that queries will not include the field(s) required by this mapping by default. This can only be used if the descriptor has a FetchGroupManager and class implements the FetchGroupTracker interface (or is weaved). This is not the same as indirection on relationships (lazy relationships), as it defers the loading of the source object fields, not the relationship.

                                  throws DescriptorException

INTERNAL: Add or removes a new value and its change set to the collection change record based on the event passed in. This is used by attribute change tracking.

Throws:

DescriptorException

setChangeListener

public void setChangeListener(java.lang.Object clone,
                              java.beans.PropertyChangeListener listener,
                              org.eclipse.persistence.internal.sessions.UnitOfWorkImpl uow)

INTERNAL: Set the change listener if required. This is required for collections and aggregates or other change tracked mutable objects. This is used for resuming or flushing units of work.

setDerivesId

public void setDerivesId(boolean derivesId)

ADVANCED: Used to indicate the mapping references a JPA ID or MapsId attribute for the CMP3Policy and JPA Id classes (as well as Embeddable Id classes). This is different from isPrimaryKeyMapping, as an ID mapping is user specified and can be read only, as long as another writable mapping for the field exists.

setDerivedIdMapping

public void setDerivedIdMapping(DatabaseMapping derivedIdMapping)

ADVANCED: Used to indicate the mapping references a JPA ID or MapsId attribute for the CMP3Policy and JPA Id classes (as well as Embeddable Id classes). This is different from isPrimaryKeyMapping, as an ID mapping is user specified and can be read only, as long as another writable mapping for the field exists.

INTERNAL: Directly build a change record without comparison

Throws:

DescriptorException

postCalculateChanges

public void postCalculateChanges(ChangeRecord changeRecord,
                                 org.eclipse.persistence.internal.sessions.UnitOfWorkImpl uow)

INTERNAL: Overridden by mappings that require additional processing of the change record after the record has been calculated.

postCalculateChangesOnDeleted

public void postCalculateChangesOnDeleted(java.lang.Object deletedObject,
                                          org.eclipse.persistence.internal.sessions.UnitOfWorkChangeSet uowChangeSet,
                                          org.eclipse.persistence.internal.sessions.UnitOfWorkImpl uow)

INTERNAL: Overridden by mappings that require objects to be deleted contribute to change set creation.

recordPrivateOwnedRemovals

public void recordPrivateOwnedRemovals(java.lang.Object object,
                                       org.eclipse.persistence.internal.sessions.UnitOfWorkImpl uow)

INTERNAL: Overridden by mappings that require objects to be deleted contribute to change set creation.
