 JsonMapper jsonMapper,
 ZeebeClientConfiguration config,
 Predicate<Throwable> retryPredicate)

CreateProcessInstanceCommandImpl

public CreateProcessInstanceCommandImpl(GatewayGrpc.GatewayStub asyncStub,

 Duration requestTimeout,
 Predicate<Throwable> retryPredicate)

Deprecated.

since 8.3.0, use CreateProcessInstanceCommandImpl(GatewayStub asyncStub, JsonMapper jsonMapper, ZeebeClientConfiguration config, Predicate retryPredicate)

A constructor that provides an instance with the tenantId set.

From version 8.3.0, the java client supports multi-tenancy for this command, which requires the tenantId property to be defined. This constructor is only intended for backwards compatibility in tests.

Method Details

setVariablesInternal

protected CreateProcessInstanceCommandImpl setVariablesInternal(String variables)

Specified by:

setVariablesInternal in class CommandWithVariables<CreateProcessInstanceCommandImpl>

startBeforeElement

public CreateProcessInstanceCommandStep1.CreateProcessInstanceCommandStep3 startBeforeElement(String elementId)

Description copied from interface: CreateProcessInstanceCommandStep1.CreateProcessInstanceCommandStep3

Overrides the default start position of the process. Calling this method will make the process start at the given elementId, if possible. This method can be called more than once to simultaneously start at different elements in different branches of the process.

Specified by:

startBeforeElement in interface CreateProcessInstanceCommandStep1.CreateProcessInstanceCommandStep3

Parameters:

elementId - the id of the BPMN element where to start the process instance

Returns:

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

withResult

public CreateProcessInstanceCommandStep1.CreateProcessInstanceWithResultCommandStep1 withResult()

Description copied from interface: CreateProcessInstanceCommandStep1.CreateProcessInstanceCommandStep3

When this method is called, the response to the command will be received after the process is completed. The response consists of a set of variables.

Specified by:

withResult in interface CreateProcessInstanceCommandStep1.CreateProcessInstanceCommandStep3

Returns:

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

bpmnProcessId

public CreateProcessInstanceCommandStep1.CreateProcessInstanceCommandStep2 bpmnProcessId(String id)

Description copied from interface: CreateProcessInstanceCommandStep1

Set the BPMN process id of the process to create an instance of. This is the static id of the process in the BPMN XML (i.e. "<bpmn:process id='my-process'>").

Specified by:

bpmnProcessId in interface CreateProcessInstanceCommandStep1

Parameters:

id - the BPMN process id of the process

Returns:

the builder for this command

processDefinitionKey

public CreateProcessInstanceCommandStep1.CreateProcessInstanceCommandStep3 processDefinitionKey(long processDefinitionKey)

Description copied from interface: CreateProcessInstanceCommandStep1

Set the key of the process to create an instance of. The key is assigned by the broker while deploying the process. It can be picked from the deployment or process event.

Specified by:

processDefinitionKey in interface CreateProcessInstanceCommandStep1

Parameters:

processDefinitionKey - the key of the process

Returns:

the builder for this command

version

public CreateProcessInstanceCommandStep1.CreateProcessInstanceCommandStep3 version(int version)

Description copied from interface: CreateProcessInstanceCommandStep1.CreateProcessInstanceCommandStep2

Set the version of the process to create an instance of. The version is assigned by the broker while deploying the process. It can be picked from the deployment or process event.

Specified by:

version in interface CreateProcessInstanceCommandStep1.CreateProcessInstanceCommandStep2

Parameters:

version - the version of the process

Returns:

the builder for this command

latestVersion

public CreateProcessInstanceCommandStep1.CreateProcessInstanceCommandStep3 latestVersion()

Description copied from interface: CreateProcessInstanceCommandStep1.CreateProcessInstanceCommandStep2

Use the latest version of the process to create an instance of.

If the latest version was deployed few moments before then it can happen that the new instance is created of the previous version.

Specified by:

latestVersion in interface CreateProcessInstanceCommandStep1.CreateProcessInstanceCommandStep2

Returns:

the builder for this command

requestTimeout

public FinalCommandStep<ProcessInstanceEvent> 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<ProcessInstanceEvent>

Parameters:

requestTimeout - the request timeout

Returns:

the configured command

send

public ZeebeFuture<ProcessInstanceEvent> 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&#62 future = command.send();
 JobEvent event = future.join();
 

Specified by:

send in interface FinalCommandStep<ProcessInstanceEvent>

Returns:

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

tenantId

public CreateProcessInstanceCommandStep1.CreateProcessInstanceCommandStep3 tenantId(String tenantId)

Description copied from interface: CommandWithTenantStep

Experimental: This method is under development, and as such using it may have no effect on the command builder when called. While unimplemented, it simply returns the command builder instance unchanged. This method already exists for software that is building support for multi-tenancy, and already wants to use this API during its development. As support for multi-tenancy is added to Zeebe, each of the commands that implement this method may start to take effect. Until this warning is removed, anything described below may not yet have taken effect, and the interface and its description are subject to change.

Specifies the tenant that will own any entities (e.g. process definition, process instances, etc.) resulting from this command, or that owns any entities (e.g. jobs) referred to from this command.

Multi-tenancy

Multiple tenants can share a Zeebe cluster. Entities can be assigned to a specific tenant using an identifier. Only that tenant can access these entities.

Any entities created before multi-tenancy has been enabled in the Zeebe cluster, are assigned to the CommandWithTenantStep.DEFAULT_TENANT_IDENTIFIER.

If no tenant is explicitly specified, then the command is rejected.

Specified by:

tenantId in interface CommandWithTenantStep<CreateProcessInstanceCommandStep1.CreateProcessInstanceCommandStep3>

Parameters:

tenantId - the identifier of the tenant to specify for this command, e.g. "ACME"

Returns:

the builder for this command with the tenant specified
