Method Detail

createPrimaryKeyFromId

public java.lang.Object createPrimaryKeyFromId(java.lang.Object key,
                                               AbstractSession session)

Description copied from class: CMP3Policy

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 CMP3Policy

initializePrimaryKeyFields

protected KeyElementAccessor[] initializePrimaryKeyFields(java.lang.Class keyClass,
                                                          AbstractSession session)

Description copied from class: CMP3Policy

INTERNAL: Cache the bean's primary key fields so speed up creating of primary key objects and initialization of beans. Note, we have to re-look up the fields for the bean class since these fields may have been loaded with the wrong loader (thank you Kirk). If the key is compound, we also have to look up the fields for the key.

Overrides:

initializePrimaryKeyFields in class CMP3Policy
