示例1: getRollbackCandidates
import org.apache.commons.collections.CollectionUtils; //导入方法依赖的package包/类
public List<MigrationTask> getRollbackCandidates(List<MigrationTask> allMigrationTasks, int[] rollbackLevels, PatchInfoStore currentPatchInfoStore) throws MigrationException
{
validateRollbackLevel(rollbackLevels);
int rollbackLevel = rollbackLevels[0];
int currentPatchLevel = currentPatchInfoStore.getPatchLevel();
if (currentPatchLevel < rollbackLevel)
{
throw new MigrationException(
"The rollback patch level cannot be greater than the current patch level");
}
PatchRollbackPredicate rollbackPredicate = new PatchRollbackPredicate(currentPatchLevel,
rollbackLevel);
List<MigrationTask> migrationCandidates = new ArrayList<MigrationTask>();
migrationCandidates.addAll(allMigrationTasks);
CollectionUtils.filter(migrationCandidates, rollbackPredicate);
Collections.sort(migrationCandidates);
// need to reverse the list do we apply the rollbacks in descending
// order
Collections.reverse(migrationCandidates);
return migrationCandidates;
