                                 ZeebeClientConfiguration configuration,
                                 ZeebeObjectMapper objectMapper,

Method Detail

setVariablesInternal

protected PublishMessageCommandImpl setVariablesInternal(String variables)

Specified by:

setVariablesInternal in class CommandWithVariables<PublishMessageCommandImpl>

messageId

public PublishMessageCommandStep1.PublishMessageCommandStep3 messageId(String messageId)

Description copied from interface: PublishMessageCommandStep1.PublishMessageCommandStep3

Set the id of the message. The message is rejected if another message is already published with the same id, name and correlation-key.

Specified by:

messageId in interface PublishMessageCommandStep1.PublishMessageCommandStep3

Parameters:

messageId - the id of the message

Returns:

the builder for this command. Call FinalCommandStep.send() to complete the command and send it to the broker.

timeToLive

public PublishMessageCommandStep1.PublishMessageCommandStep3 timeToLive(Duration timeToLive)

Description copied from interface: PublishMessageCommandStep1.PublishMessageCommandStep3

Set the time-to-live of the message. The message can only be correlated within the given time-to-live.

If the duration is zero or negative then the message can only be correlated to open subscriptions (e.g. to an entered message catch event).

If no duration is set then the default is used from the configuration.

Specified by:

timeToLive in interface PublishMessageCommandStep1.PublishMessageCommandStep3

Parameters:

timeToLive - the time-to-live of the message

Returns:

the builder for this command. Call FinalCommandStep.send() to complete the command and send it to the broker.

correlationKey

public PublishMessageCommandStep1.PublishMessageCommandStep3 correlationKey(String correlationKey)

Description copied from interface: PublishMessageCommandStep1.PublishMessageCommandStep2

Set the value of the correlation key of the message.

This value will be used together with the message name to find matching message subscriptions.

Specified by:

correlationKey in interface PublishMessageCommandStep1.PublishMessageCommandStep2

Parameters:

correlationKey - the correlation key value of the message

Returns:

the builder for this command

messageName

public PublishMessageCommandStep1.PublishMessageCommandStep2 messageName(String messageName)

Description copied from interface: PublishMessageCommandStep1

Set the name of the message.

Specified by:

messageName in interface PublishMessageCommandStep1

Parameters:

messageName - the name of the message

Returns:

the builder for this command

requestTimeout

public FinalCommandStep<PublishMessageResponse> requestTimeout(Duration requestTimeout)

Description copied from interface: FinalCommandStep

Sets the request timeout for the command. The default request timeout can be configured using ZeebeClientBuilder.defaultRequestTimeout(Duration).

Specified by:

requestTimeout in interface FinalCommandStep<PublishMessageResponse>

Parameters:

requestTimeout - the request timeout

Returns:

the configured command

send

public ZeebeFuture<PublishMessageResponse> send()

Description copied from interface: FinalCommandStep

Sends the command to the Zeebe broker. This operation is asynchronous. In case of success, the future returns the event that was generated by the Zeebe broker in response to the command.

Call ZeebeFuture.join() to wait until the response is available.

 Future<JobEvent> future = command.send();
 JobEvent event = future.join();
 

Specified by:

send in interface FinalCommandStep<PublishMessageResponse>

Returns:

a future tracking state of success/failure of the command.
