Example 12 with TransactionController

use of org.apache.derby.iapi.store.access.TransactionController in project derby by apache.

the class ConstraintDescriptor method drop.

/**
 * Drop the constraint.  Clears dependencies, drops
 * the backing index and removes the constraint
 * from the list on the table descriptor.  Does NOT
 * do an dm.invalidateFor()
 *
 * @return If the backing conglomerate for this constraint
 *  was a) dropped and b) shared by other constraints/indexes,
 *  then this method will return a ConglomerateDescriptor that
 *  describes what a new backing conglomerate must look like
 *  to stay "sharable" across the remaining constraints/indexes.
 *  It is then up to the caller to create a corresponding
 *  conglomerate.  We don't create the conglomerate here
 *  because depending on who called us, it might not make
 *  sense to create it--ex. if we get here because of a DROP
 *  TABLE, the DropTable action doesn't need to create a
 *  new backing conglomerate since the table (and all of
 *  its constraints/indexes) are going to disappear anyway.
