All Known Implementing Classes:

ProcessInstanceBuilderImpl
```
@Internal
public interface ProcessInstanceBuilder
```
Helper for starting new ProcessInstance. An instance can be obtained through RuntimeService.createProcessInstanceBuilder(). processDefinitionId or processDefinitionKey should be set before calling start() to start a process instance.

  - processDefinitionId
```
ProcessInstanceBuilder processDefinitionId(String processDefinitionId)
```
    Set the id of the process definition
  - processDefinitionKey
```
ProcessInstanceBuilder processDefinitionKey(String processDefinitionKey)
```
    Set the key of the process definition, latest version of the process definition with the given key. If processDefinitionId was set this will be ignored
  - messageName
```
ProcessInstanceBuilder messageName(String messageName)
```
    Set the message name that needs to be used to look up the process definition that needs to be used to start the process instance.
  - name
```
ProcessInstanceBuilder name(String processInstanceName)
```
    Set the name of process instance
  - businessKey
```
ProcessInstanceBuilder businessKey(String businessKey)
```
    Set the businessKey of process instance
  - tenantId
```
ProcessInstanceBuilder tenantId(String tenantId)
```
    Set the tenantId of process instance
  - variables
```
ProcessInstanceBuilder variables(Map<String,Object> variables)
```
    Sets the process variables
  - variable
```
ProcessInstanceBuilder variable(String variableName,
                                Object value)
```
    Adds a variable to the process instance
  - transientVariables
```
ProcessInstanceBuilder transientVariables(Map<String,Object> transientVariables)
```
    Sets the transient variables
  - transientVariable
```
ProcessInstanceBuilder transientVariable(String variableName,
                                         Object value)
```
    Adds a transient variable to the process instance
  - start
```
ProcessInstance start()
```
    Start the process instance
    
    Throws:
    
    ActivitiIllegalArgumentException - if processDefinitionKey and processDefinitionId are null
    
    ActivitiObjectNotFoundException - when no process definition is deployed with the given processDefinitionKey or processDefinitionId
  - create
```
ProcessInstance create()
```
    Create the process instance
    
    Throws:
    
    ActivitiIllegalArgumentException - if processDefinitionKey and processDefinitionId are null
    
    ActivitiObjectNotFoundException - when no process definition is deployed with the given processDefinitionKey or processDefinitionId
