Method Detail

getOrder

public int getOrder()

Description copied from interface: Ordered

Return the order value of this object, with a higher value meaning greater in terms of sorting.

Normally starting with 0, with Integer.MAX_VALUE indicating the greatest value. Same order values will result in arbitrary positions for the affected objects.

Higher values can be interpreted as lower priority. As a consequence, the object with the lowest value has highest priority (somewhat analogous to Servlet "load-on-startup" values).

Specified by:

getOrder in interface Ordered

Returns:

the order value

flushResource

public void flushResource(PersistenceManagerHolder resourceHolder)

Description copied from class: ResourceHolderSynchronization

Flush callback for the given resource holder.

Overrides:

flushResource in class ResourceHolderSynchronization<PersistenceManagerHolder,PersistenceManagerFactory>

Parameters:

resourceHolder - the resource holder to flush

shouldUnbindAtCompletion

protected boolean shouldUnbindAtCompletion()

Description copied from class: ResourceHolderSynchronization

Return whether this holder should be unbound at completion (or should rather be left bound to the thread after the transaction).

The default implementation returns true.

Overrides:

shouldUnbindAtCompletion in class ResourceHolderSynchronization<PersistenceManagerHolder,PersistenceManagerFactory>

shouldReleaseAfterCompletion

protected boolean shouldReleaseAfterCompletion(PersistenceManagerHolder resourceHolder)

Description copied from class: ResourceHolderSynchronization

Return whether this holder's resource should be released after transaction completion (true).

The default implementation returns !shouldReleaseBeforeCompletion(), releasing after completion if no attempt was made before completion.

Overrides:

shouldReleaseAfterCompletion in class ResourceHolderSynchronization<PersistenceManagerHolder,PersistenceManagerFactory>

See Also:

ResourceHolderSynchronization.releaseResource(H, K)

releaseResource

protected void releaseResource(PersistenceManagerHolder resourceHolder,
                   PersistenceManagerFactory resourceKey)

Description copied from class: ResourceHolderSynchronization

Release the given resource (after it has been unbound from the thread).

Overrides:

releaseResource in class ResourceHolderSynchronization<PersistenceManagerHolder,PersistenceManagerFactory>

Parameters:

resourceHolder - the resource holder to process

resourceKey - the key that the ResourceHolder was bound for
