All Implemented Interfaces:

TransactionSynchronizer

public class FlowScopeTokenTransactionSynchronizer
extends AbstractTokenTransactionSynchronizer

The default transaction synchronizer implementation. The token will be stored in flow scope for the duration of an application transaction. This implies that there needs to be a unique flow execution for each running application transaction! As a result this transaction synchronizer cannot be used with continuations based flow execution storage strategies.

Method Detail

getToken

public java.lang.String getToken(RequestContext context)

Description copied from class: AbstractTokenTransactionSynchronizer

Obtain the token value from whatever token storage is being used (e.g. from the flow scope).

Specified by:

getToken in class AbstractTokenTransactionSynchronizer

Parameters:

context - the flow execution request context

Returns:

the retreived token, or null if no token could be found

setToken

public void setToken(RequestContext context,
                     java.lang.String token)

Description copied from class: AbstractTokenTransactionSynchronizer

Set given token in whatever token storage is being used (e.g the flow scope).

Specified by:

setToken in class AbstractTokenTransactionSynchronizer

Parameters:

context - the flow execution request context

token - the token value to set

clearToken

public void clearToken(RequestContext context)

Description copied from class: AbstractTokenTransactionSynchronizer

Clear the token from whatever token storage is being used (e.g the flow scope). This will end transactional processing.

Specified by:

clearToken in class AbstractTokenTransactionSynchronizer

Parameters:

context - the flow execution request context
