Method Detail

createPrimaryKeyFromId

public java.lang.Object createPrimaryKeyFromId(java.lang.Object key,
                                               org.eclipse.persistence.internal.sessions.AbstractSession session)

Description copied from class: CMPPolicy

INTERNAL: Use the key to create a EclipseLink primary key. If the key is simple (direct mapped) then just add it to a vector, otherwise must go through the inefficient process of copying the key into the bean and extracting the key from the bean.

Overrides:

createPrimaryKeyFromId in class org.eclipse.persistence.internal.jpa.CMP3Policy

initializePrimaryKeyFields

protected CMPPolicy.KeyElementAccessor[] initializePrimaryKeyFields(java.lang.Class keyClass,
                                                                    org.eclipse.persistence.internal.sessions.AbstractSession session)

Overrides:

initializePrimaryKeyFields in class org.eclipse.persistence.internal.jpa.CMP3Policy
