Method Details

deleteEntriesOlderThan

public void deleteEntriesOlderThan(Date theCutoffDate)

Perform removal of entries older than theCutoffDate since the create operations are done.

deleteByResId

public void deleteByResId(JpaPid theResId)

Once a resource is updated or deleted, we can trust that future match checks will find the committed resource in the db. The use of the constraint table is done, and we can delete it to keep the table small.

deleteByResIds

public void deleteByResIds(Collection<JpaPid> theResId)

Once a resource is updated or deleted, we can trust that future match checks will find the committed resource in the db. The use of the constraint table is done, and we can delete it to keep the table small.

enforceMatchUrlResourceUniqueness

public void enforceMatchUrlResourceUniqueness(String theResourceName,
 String theMatchUrl,
 ResourceTable theResourceTable)

Parameters:

theResourceName - The resource name associated with the conditional URL

theMatchUrl - The URL parameters portion of the match URL. Should not include a leading ?, but can include & separators. We store a record of match urls with res_id so a db constraint can catch simultaneous creates that slip through.
