 class HollowState
extends PCState

Lifecycle state. Represents a hollow instance that exists in the data store, but whose state has not been loaded and who is not active in the current transaction (if any). This may be the state of instances returned on ID lookups or by traversing relations, and the state of persistent instances outside of transactions (unless the retainValues flag is set in the Broker).

HollowState()
Method Detail

initialize

void initialize(StateManagerImpl context)
Description copied from class: PCState
Called when this state is first assigned to the given state manager.

Overrides:
initialize in class PCState

delete

PCState delete(StateManagerImpl context)
Description copied from class: PCState
Perform any actions necesssary and return the proper lifecycle state on a call to Broker.delete(java.lang.Object, org.apache.openjpa.kernel.OpCallbacks) with the given instance. Returns the this pointer by default.

Overrides:
delete in class PCState

transactional

PCState transactional(StateManagerImpl context)
Description copied from class: PCState
Perform any actions necesssary and return the proper lifecycle state on a call to StoreContext.nontransactional(java.lang.Object, org.apache.openjpa.kernel.OpCallbacks) with the given instance. Returns the this pointer by default.

Overrides:
transactional in class PCState

release

PCState release(StateManagerImpl context)
Description copied from class: PCState
Perform any actions necesssary and return the proper lifecycle state on a call to Broker#makeTransient with the given instance. Returns the this pointer by default.

Overrides:
release in class PCState

beforeRead

PCState beforeRead(StateManagerImpl context,
                   int field)
Description copied from class: PCState
Perform any actions necesssary and return the proper lifecycle state prior to the state of the given instance being read within an active transaction. The given field number can be -1 if it is a general object read. Returns the this pointer by default.

Overrides:
beforeRead in class PCState

beforeOptimisticRead

PCState beforeOptimisticRead(StateManagerImpl context,
                             int field)
Description copied from class: PCState
Perform any actions necesssary and return the proper lifecycle state prior to the state of the given instance being read in an optimistic transaction. The given field number can be -1 if it is a general object read. Returns the this pointer by default.

Overrides:
beforeOptimisticRead in class PCState

beforeNontransactionalRead

PCState beforeNontransactionalRead(StateManagerImpl context,
                                   int field)
Description copied from class: PCState
Perform any actions necesssary and return the proper lifecycle state prior to the state of the given instance being read outside of an active transaction. The given field number can be -1 if it is a general object read. Returns the this pointer by default.

Overrides:
beforeNontransactionalRead in class PCState

beforeWrite

Description copied from class: PCState
Perform any actions necesssary and return the proper lifecycle state prior to the state of the given instance being written within an active transaction. The mutate parameter tells if it is a direct mutation on an SCO field. Returns the this pointer by default.

Overrides:
beforeWrite in class PCState
