public class RemoteChunkingManagerStepBuilder<I,O>
extends FaultTolerantStepBuilder<I,O>

Builder for a manager step in a remote chunking setup. This builder creates and sets a ChunkMessageChannelItemWriter on the manager step.

If no messagingTemplate is provided through messagingTemplate(MessagingTemplate), this builder will create one and set its default channel to the outputChannel provided through outputChannel(MessageChannel).

If a messagingTemplate is provided, it is assumed that it is fully configured and that its default channel is set to an output channel on which requests to workers will be sent.

Returns:

this for fluent chaining

keyGenerator

public RemoteChunkingManagerStepBuilder<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 class FaultTolerantStepBuilder<I,O>

keyGenerator - a key generator for the stateful retry

Returns:

this for fluent chaining

retryLimit

public RemoteChunkingManagerStepBuilder<I,O> retryLimit(int retryLimit)

Overrides:

retryLimit in class FaultTolerantStepBuilder<I,O>

Parameters:

retryLimit - the retry limit (default 0)

Returns:

this for fluent chaining

retryPolicy

public RemoteChunkingManagerStepBuilder<I,O> retryPolicy(org.springframework.retry.RetryPolicy retryPolicy)

Provide an explicit retry policy instead of using the FaultTolerantStepBuilder.retryLimit(int) and retryable exceptions provided elsewhere. Can be used to retry different exceptions a different number of times, for instance.

Overrides:

retryPolicy in class FaultTolerantStepBuilder<I,O>

Parameters:

retryPolicy - a retry policy

Returns:

this for fluent chaining

backOffPolicy

public RemoteChunkingManagerStepBuilder<I,O> backOffPolicy(org.springframework.retry.backoff.BackOffPolicy backOffPolicy)

Description copied from class: FaultTolerantStepBuilder

Overrides:

backOffPolicy in class FaultTolerantStepBuilder<I,O>

Parameters:

backOffPolicy - the back off policy to use (default no backoff)

Returns:

this for fluent chaining

retryContextCache

public RemoteChunkingManagerStepBuilder<I,O> retryContextCache(org.springframework.retry.policy.RetryContextCache retryContextCache)

Description copied from class: FaultTolerantStepBuilder

Overrides:

retryContextCache in class FaultTolerantStepBuilder<I,O>

Parameters:

retryContextCache - cache for retry contexts in between transactions (default to standard in-memory implementation)

Returns:

this for fluent chaining

skipLimit

public RemoteChunkingManagerStepBuilder<I,O> skipLimit(int skipLimit)

Description copied from class: FaultTolerantStepBuilder

Sets the maximum number of failed items to skip before the step fails. Ignored if an explicit FaultTolerantStepBuilder.skipPolicy(SkipPolicy) is provided.

Description copied from class: FaultTolerantStepBuilder

Explicitly prevent certain exceptions (and subclasses) from being skipped.

Overrides:

noSkip in class FaultTolerantStepBuilder<I,O>

Parameters:

type - the non-skippable exception

Returns:

this for fluent chaining

skip

public RemoteChunkingManagerStepBuilder<I,O> skip(Class<? extends Throwable> type)

Description copied from class: FaultTolerantStepBuilder

Explicitly request certain exceptions (and subclasses) to be skipped. These exceptions (and their subclasses) might be thrown during any phase of the chunk processing (read, process, write) but separate counts are made of skips on read, process and write inside the step execution.

Overrides:

skip in class FaultTolerantStepBuilder<I,O>

Parameters:

type - the exception type.

Returns:

this for fluent chaining

skipPolicy

public RemoteChunkingManagerStepBuilder<I,O> skipPolicy(SkipPolicy skipPolicy)

skipPolicy in class FaultTolerantStepBuilder<I,O>

Parameters:

skipPolicy - the skip policy

Returns:

this for fluent chaining

noRollback

public RemoteChunkingManagerStepBuilder<I,O> noRollback(Class<? extends Throwable> type)

type - the exception to mark as no rollback

Returns:

this for fluent chaining
