UnitOfWork.Phase| Constructor and Description |
|---|
BatchingUnitOfWork(List<T> messages)
Initializes a BatchingUnitOfWork for processing the given list of
messages. |
BatchingUnitOfWork(T... messages)
Initializes a BatchingUnitOfWork for processing the given batch of
messages. |
| Modifier and Type | Method and Description |
|---|---|
protected void |
addHandler(UnitOfWork.Phase phase,
Consumer<UnitOfWork<T>> handler)
Register the given
handler with the Unit of Work. |
<R> R |
executeWithResult(Callable<R> task,
RollbackConfiguration rollbackConfiguration)
Execute the given
task in the context of this Unit of Work. |
ExecutionResult |
getExecutionResult()
Get the result of the task that was executed by this Unit of Work.
|
Map<Message<?>,ExecutionResult> |
getExecutionResults()
Returns a Map of
ExecutionResult per Message. |
T |
getMessage()
Get the message that is being processed by the Unit of Work.
|
List<? extends Message<?>> |
getMessages()
Get the batch of messages that is being processed (or has been processed) by this unit of work.
|
boolean |
isFirstMessage()
Checks if the message being processed now is the first of the batch being processed in this unit of work.
|
boolean |
isFirstMessage(Message<?> message)
Checks if the given
message is the first of the batch being processed in this unit of work. |
boolean |
isLastMessage()
Checks if the message being processed now is the last of the batch being processed in this unit of work.
|
boolean |
isLastMessage(Message<?> message)
Checks if the given
message is the last of the batch being processed in this unit of work. |
protected void |
notifyHandlers(UnitOfWork.Phase phase)
Notify the handlers attached to the given
phase. |
protected void |
setExecutionResult(ExecutionResult executionResult)
Set the execution result of processing the current
Message. |
protected void |
setRollbackCause(Throwable cause)
Sets the cause for rolling back this Unit of Work.
|
UnitOfWork<T> |
transformMessage(Function<T,? extends Message<?>> transformOperator)
Transform the Message being processed using the given operator and stores the result.

it will be started.
If the task executes successfully the Unit of Work is committed and the result of the task is returned. If
execution fails, the rollbackConfiguration determines if the Unit of Work should be rolled back or
committed.
This implementation executes the given
task for each of its messages. The return value is the

UnitOfWorkImplementations should take caution not to change the message type to a type incompatible with the current Unit of Work. For example, do not return a CommandMessage when transforming an EventMessage.

Note that the value of the returned ExecutionResult's ExecutionResult.isExceptionResult() does not
determine whether or not the UnitOfWork has been rolled back. To check whether or not the UnitOfWork was rolled
back check UnitOfWork.isRolledBack().
