Class AbstractTransactionalOperation<E extends Entity>

java.lang.Object
  de.schwarzrot.data.transaction.support.AbstractTransactionalOperation<E>

Type Parameters:

E - - the entity this operation is related to

All Implemented Interfaces:

TransactionalOperation<E>

Direct Known Subclasses:

AbstractConditionTransactionalOperation, TOClear, TOContextOperation, TOSave

public abstract class AbstractTransactionalOperation<E extends Entity>
extends Object
implements TransactionalOperation<E>

base class for descriptive elements, that declare an operation, that should be bound by a transaction. A transaction holds a number of operation declarations, which will be executed at transaction execution time.

A transaction operation is always bound to an Entity, no matter, whether that Entity is used as entry parameter or will be the result of the operation.
