Detailed Description

Simple implementation of executing the step as a call to a ITasklet, possibly repeated, and each call surrounded by a transaction. The structure is therefore that of a loop with transaction boundary inside the loop. The loop is controlled by the step operations (StepOperations=RepeatOperations)).

Clients can use interceptors in the step operations to intercept or listen to the iteration on a step-wide basis, for instance to get a callback when the step is complete. Those that want callbacks at the level of an individual tasks, can specify interceptors for the chunk operations.

Constructor & Destructor Documentation

Summer.Batch.Core.Step.Tasklet.TaskletStep.TaskletStep ( string name )

Custom constructor with name.

Parameters

name

Summer.Batch.Core.Step.Tasklet.TaskletStep.TaskletStep ( )

Default constructor.

Member Function Documentation

override void Summer.Batch.Core.Step.Tasklet.TaskletStep.Close ( ExecutionContext ctx )

protectedvirtual

Delegates to composite stream closes.

Parameters

ctx

Reimplemented from Summer.Batch.Core.Step.AbstractStep.

Semaphore Summer.Batch.Core.Step.Tasklet.TaskletStep.CreateSemaphore ( )

protected

Extension point mainly for test purposes so that the behaviour of the lock can be manipulated to simulate various pathologies.

Returns: a semaphore for locking access to the JobRepository

void Summer.Batch.Core.Step.Tasklet.TaskletStep.Dispose ( )

see https://msdn.microsoft.com/fr-fr/library/ms244737.aspx

override void Summer.Batch.Core.Step.Tasklet.TaskletStep.DoExecute ( StepExecution stepExecution )

protectedvirtual

Actual taskletstep execution.

Parameters

stepExecution

Exceptions

Exception

Implements Summer.Batch.Core.Step.AbstractStep.

override void Summer.Batch.Core.Step.Tasklet.TaskletStep.Open ( ExecutionContext ctx )

protectedvirtual

Delegates to composite stream open

Parameters

ctx

Reimplemented from Summer.Batch.Core.Step.AbstractStep.

void Summer.Batch.Core.Step.Tasklet.TaskletStep.RegisterStream ( IItemStream stream )

Register a single IItemStream for callbacks to the stream interface.

Parameters

stream

void Summer.Batch.Core.Step.Tasklet.TaskletStep.SetStreams ( IItemStream[] streams )

Register each of the streams for callbacks at the appropriate time in the step. The IItemReader and IItemWriter are automatically registered, but it doesn't hurt to also register them here. Injected dependencies of the reader and writer are not automatically registered, so if you implement ItemWriter using delegation to another object which itself is a IItemStream, you need to register the delegate here.

Parameters

streams
