ChunkMessageChannelItemWriter.setMaxWaitTimeouts(int)
throttleLimit
public RemoteChunkingMasterStepBuilder<I,O> throttleLimit(long throttleLimit)

- the throttle limit to set- See Also:
ChunkMessageChannelItemWriter.setThrottleLimit(long)
build
public TaskletStep build()
Build a masterTaskletStep
.- Overrides:
build
in classFaultTolerantStepBuilder<I,O>
- Returns:
- the configured master step
- See Also:
RemoteChunkHandlerFactoryBean
reader
public RemoteChunkingMasterStepBuilder<I,O> reader(ItemReader<? extends I> reader)
Description copied from class:SimpleStepBuilder
An item reader that provides a stream of items. Will be automatically registered as aAbstractTaskletStepBuilder.stream(ItemStream)
or listener if it implements the corresponding interface. By default assumed to be non-transactional.- Overrides:
reader
in classSimpleStepBuilder<I,O>
- Parameters:
reader
- an item reader- Returns:
- this for fluent chaining
- See Also:
SimpleStepBuilder.readerTransactionalQueue
repository
public RemoteChunkingMasterStepBuilder<I,O> repository(JobRepository jobRepository)
- Overrides:
repository
in classStepBuilderHelper<AbstractTaskletStepBuilder<SimpleStepBuilder<I,O>>>
transactionManager
public RemoteChunkingMasterStepBuilder<I,O> transactionManager(org.springframework.transaction.PlatformTransactionManager transactionManager)

Description copied from class:FaultTolerantStepBuilder
Register a skip listener.- Overrides:
listener
in classFaultTolerantStepBuilder<I,O>

listener
- the listener to register- Returns:
- this for fluent chaining
listener
public RemoteChunkingMasterStepBuilder<I,O> listener(ChunkListener listener)
Description copied from class:AbstractTaskletStepBuilder
Register a chunk listener.- Overrides:
listener
in classFaultTolerantStepBuilder<I,O>

- the listener to register- Returns:
- this for fluent chaining

public RemoteChunkingMasterStepBuilder<I,O> listener(org.springframework.retry.RetryListener listener)
Description copied from class:FaultTolerantStepBuilder

keyGenerator
public RemoteChunkingMasterStepBuilder<I,O> keyGenerator(KeyGenerator keyGenerator)
Description copied from class:FaultTolerantStepBuilder
Sets the key generator for identifying retried items. Retry across transaction boundaries requires items to be identified when they are encountered again. The default strategy is to use the items themselves, relying on their own implementation to ensure that they can be identified. Often a key generator is not necessary as long as the items have reliable hash code and equals implementations, or the reader is not transactional (the default) and the item processor either is itself not transactional (not the default) or does not create new items.- Overrides:
keyGenerator
in classFaultTolerantStepBuilder<I,O>

- this for fluent chaining

- Parameters:
retryLimit
- the retry limit (default 0)- Returns:
- this for fluent chaining
retryPolicy
public RemoteChunkingMasterStepBuilder<I,O> retryPolicy(org.springframework.retry.RetryPolicy retryPolicy)

Provide an explicit retry policy instead of using theFaultTolerantStepBuilder.retryLimit(int)
and retryable exceptions provided elsewhere. Can be used to retry different exceptions a different number of times, for instance.- Overrides:
retryPolicy
in classFaultTolerantStepBuilder<I,O>
- Parameters:
retryPolicy
- a retry policy- Returns:
- this for fluent chaining
backOffPolicy
public RemoteChunkingMasterStepBuilder<I,O> backOffPolicy(org.springframework.retry.backoff.BackOffPolicy backOffPolicy)

- this for fluent chaining
