Method Detail

_p_getIdentity

public IdentityIF _p_getIdentity()

Description copied from interface: PersistentIF

INTERNAL: Returns the identity of the object.

Specified by:

_p_getIdentity in interface PersistentIF

_p_getType

public Class<?> _p_getType()

Description copied from interface: PersistentIF

INTERNAL: Returns the object.type. This information is used by the transaction to handle the persistent mapping for the object.

Specified by:

_p_getType in interface PersistentIF

_p_setIdentity

public void _p_setIdentity(IdentityIF identity)

Description copied from interface: PersistentIF

INTERNAL: Sets the identity of the object.

Specified by:

_p_setIdentity in interface PersistentIF

_p_getTransaction

public TransactionIF _p_getTransaction()

Description copied from interface: PersistentIF

INTERNAL: Returns the transaction that is responible for managing the object.

Specified by:

_p_getTransaction in interface PersistentIF

_p_setTransaction

public void _p_setTransaction(TransactionIF txn)

Description copied from interface: PersistentIF

INTERNAL: Sets the transaction that is responible for managing the object.

Specified by:

_p_setTransaction in interface PersistentIF

loadField

protected <F> F loadField(int field)

INTERNAL: Called when the instance requests the value of the specified field value. This call will lead to the value being retrieved from the data repository.

loadFieldNoCheck

protected <F> F loadFieldNoCheck(int field)
                          throws IdentityNotFoundException
