Deprecated.

Use RemotePartitioningManagerStepBuilder instead.

@Deprecated
public class RemotePartitioningMasterStepBuilder
extends PartitionStepBuilder

Builder for a master step in a remote partitioning setup. This builder creates and sets a MessageChannelPartitionHandler on the master 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.

Constructor Detail

RemotePartitioningMasterStepBuilder

public RemotePartitioningMasterStepBuilder(java.lang.String stepName)

Deprecated.

Create a new RemotePartitioningMasterStepBuilder.

Parameters:

stepName - name of the master step

Method Detail

inputChannel

public RemotePartitioningMasterStepBuilder inputChannel(org.springframework.messaging.MessageChannel inputChannel)

Deprecated.

Set the input channel on which replies from workers will be received.

Parameters:

inputChannel - the input channel

Returns:

this builder instance for fluent chaining

outputChannel

public RemotePartitioningMasterStepBuilder outputChannel(org.springframework.messaging.MessageChannel outputChannel)

Deprecated.

Set the output channel on which requests to workers will be sent. By using this setter, a default messaging template will be created and the output channel will be set as its default channel.

Use either this setter or messagingTemplate(MessagingTemplate) to provide a fully configured messaging template.

Parameters:

outputChannel - the output channel.

Returns:

this builder instance for fluent chaining

See Also:

messagingTemplate(MessagingTemplate)

messagingTemplate

public RemotePartitioningMasterStepBuilder messagingTemplate(org.springframework.integration.core.MessagingTemplate messagingTemplate)

Deprecated.

Set the MessagingTemplate to use to send data to workers. The default channel of the messaging template must be set.

Use either this setter to provide a fully configured messaging template or provide an output channel through outputChannel(MessageChannel) and a default messaging template will be created.

Parameters:

messagingTemplate - the messaging template to use

Returns:

this builder instance for fluent chaining

See Also:

outputChannel(MessageChannel)

jobExplorer

public RemotePartitioningMasterStepBuilder jobExplorer(JobExplorer jobExplorer)

Deprecated.

Set the job explorer.

Parameters:

jobExplorer - the job explorer to use.

Returns:

this builder instance for fluent chaining

pollInterval

public RemotePartitioningMasterStepBuilder pollInterval(long pollInterval)

Deprecated.

How often to poll the job repository for the status of the workers. Defaults to 10 seconds.

Parameters:

pollInterval - the poll interval value in milliseconds

Returns:

this builder instance for fluent chaining

timeout

public RemotePartitioningMasterStepBuilder timeout(long timeout)

Deprecated.

When using job repository polling, the time limit to wait. Defaults to -1 (no timeout).

Parameters:

timeout - the timeout value in milliseconds

Returns:

this builder instance for fluent chaining

beanFactory

public RemotePartitioningMasterStepBuilder beanFactory(org.springframework.beans.factory.BeanFactory beanFactory)

Deprecated.

Set the bean factory.

Parameters:

beanFactory - the bean factory to use

Returns:

this builder instance for fluent chaining

build

public Step build()

Deprecated.

Overrides:

build in class PartitionStepBuilder

repository

public RemotePartitioningMasterStepBuilder repository(JobRepository jobRepository)

Deprecated.

Overrides:

repository in class StepBuilderHelper<PartitionStepBuilder>

transactionManager

public RemotePartitioningMasterStepBuilder transactionManager(org.springframework.transaction.PlatformTransactionManager transactionManager)

Deprecated.

Overrides:

transactionManager in class StepBuilderHelper<PartitionStepBuilder>

partitioner

public RemotePartitioningMasterStepBuilder partitioner(java.lang.String slaveStepName,
                                                       Partitioner partitioner)

Deprecated.

Description copied from class: PartitionStepBuilder

Add a partitioner which can be used to create a StepExecutionSplitter. Use either this or an explicit PartitionStepBuilder.splitter(StepExecutionSplitter) but not both.

Overrides:

partitioner in class PartitionStepBuilder

Parameters:

slaveStepName - the name of the worker step (used to construct step execution names)

Parameters:

gridSize - the grid size

Returns:

this for fluent chaining

step

public RemotePartitioningMasterStepBuilder step(Step step)
