Class RebindOperationExecutor

java.lang.Object
  org.springframework.ldap.transaction.compensating.RebindOperationExecutor

All Implemented Interfaces:

CompensatingTransactionOperationExecutor

public class RebindOperationExecutor
extends Object
implements CompensatingTransactionOperationExecutor

A CompensatingTransactionOperationExecutor to manage a rebind operation. The methods in this class do not behave as expected, since it might be impossible to retrieve all the original attributes from the entry. Instead this class performs a rename in performOperation(), a negating rename in rollback(), and the commit() operation unbinds the original entry from its temporary location and binds a new entry to the original location using the attributes supplied to the original rebind opertaion.

Since:

1.2
