Method Detail

withConnectionFactory

public JmsIO.Write withConnectionFactory(javax.jms.ConnectionFactory connectionFactory)

Specify the JMS connection factory to connect to the JMS broker.

For instance:

   
    .apply(JmsIO.write().withConnectionFactory(myConnectionFactory)
   
 

Parameters:

connectionFactory - The JMS ConnectionFactory.

Returns:

The corresponding JmsIO.Read.

withQueue

public JmsIO.Write withQueue(java.lang.String queue)

Specify the JMS queue destination name where to send messages to. The JmsIO.Write acts as a producer on the queue.

This method is exclusive with withTopic(String). The user has to specify a destination: queue or topic.

For instance:

   
    .apply(JmsIO.write().withQueue("my-queue")
   
 

Parameters:

queue - The JMS queue name where to send messages to.

Returns:

The corresponding JmsIO.Read.

withTopic

public JmsIO.Write withTopic(java.lang.String topic)

Specify the JMS topic destination name where to send messages to. The JmsIO.Read acts as a publisher on the topic.

This method is exclusive with withQueue(String). The user has to specify a destination: queue or topic.

For instance:

   
    .apply(JmsIO.write().withTopic("my-topic")
   
 

Parameters:

topic - The JMS topic name.

Returns:

The corresponding JmsIO.Read.

withUsername

public JmsIO.Write withUsername(java.lang.String username)

Define the username to connect to the JMS broker (authenticated).

withPassword

public JmsIO.Write withPassword(java.lang.String password)

Define the password to connect to the JMS broker (authenticated).

expand

public PDone expand(PCollection<java.lang.String> input)

Description copied from class: PTransform

Override this method to specify how this PTransform should be expanded on the given InputT.

NOTE: This method should not be called directly. Instead apply the PTransform should be applied to the InputT using the apply method.

Composite transforms, which are defined in terms of other transforms, should return the output of one of the composed transforms. Non-composite transforms, which do not apply any transforms internally, should return a new unbound output and register evaluators (via backend-specific registration methods).

Specified by:

expand in class PTransform<PCollection<java.lang.String>,PDone>

validate

public void validate(PipelineOptions options)

Description copied from class: PTransform

Called before running the Pipeline to verify this transform is fully and correctly specified.

By default, does nothing.

Overrides:

validate in class PTransform<PCollection<java.lang.String>,PDone>
