C# Class Summer.Batch.Core.Step.Tasklet.TaskletStep

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.

Public Methods

Method	Description
Dispose ( ) : void	see https://msdn.microsoft.com/fr-fr/library/ms244737.aspx
RegisterStream ( IItemStream stream ) : void	Register a single IItemStream for callbacks to the stream interface.
SetStreams ( IItemStream streams ) : void	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.
TaskletStep ( ) : NLog	Default constructor.
TaskletStep ( string name ) : NLog	Custom constructor with name.

Protected Methods

Method	Description
Close ( Summer.Batch.Infrastructure.Item.ExecutionContext ctx ) : void	Delegates to composite stream closes.
CreateSemaphore ( ) : Semaphore	Extension point mainly for test purposes so that the behaviour of the lock can be manipulated to simulate various pathologies.
DoExecute ( StepExecution stepExecution ) : void	Actual taskletstep execution.
Open ( Summer.Batch.Infrastructure.Item.ExecutionContext ctx ) : void	Delegates to composite stream open

Private Methods
