Class DerivedBioAssay.FixDerivedBioAssayParentsRecursivelyAction

java.lang.Object

net.sf.basedb.core.DerivedBioAssay.FixDerivedBioAssayParentsRecursivelyAction

All Implemented Interfaces:

TransactionalAction

Enclosing class:

DerivedBioAssay

static class DerivedBioAssay.FixDerivedBioAssayParentsRecursivelyAction
extends Object
implements TransactionalAction

Whenever we modify the parent items to a derived bioassay, we must make sure that the physical bioassays for all child items are synchronized with the same changes. This is a bit complicated due to the fact that a single transaction may affect multiple derived bioassays at different levels in the parent-child tree. The fix must be made top-down and must handle accidentally created circular references. Whenever a change is deteced a single instance of this class is associated with the DbControl. All changed derived bioassays are collected with the add(DerivedBioAssayData) method. The actual fix is done as a last step before committing the transaction onBeforeCommit().

Method Details

get

static DerivedBioAssay.FixDerivedBioAssayParentsRecursivelyAction get(DbControl dc)

Get an instance tht handles the fixes for the given DbControl. If no instance exists yet, a new one is created.

add

void add(DerivedBioAssayData dba)

Register the given derived bioassay as one that has had it's parent items changed.

onBeforeCommit

public void onBeforeCommit()

Description copied from interface: TransactionalAction

This method is called before the commit is about to happen. If this method throws an exception the transaction will be rolled back.

Specified by:

onBeforeCommit in interface TransactionalAction

onAfterCommit

public void onAfterCommit()

Description copied from interface: TransactionalAction

Called after a successful commit. Implementations should not throw any exceptions from this method. If they do, the message is logged, by no other action is taken.

Specified by:

onAfterCommit in interface TransactionalAction

onRollback

public void onRollback()

Description copied from interface: TransactionalAction

Called after an unsuccessful commit. Implementations should not throw any exceptions from this method. If they do, the message is logged, by no other action is taken.

Specified by:

onRollback in interface TransactionalAction
