Method Detail

getStartFormData

StartFormData getStartFormData(String processDefinitionId)

Retrieves all data necessary for rendering a form to start a new process instance. This can be used to perform rendering of the forms outside of the process engine.

getRenderedStartForm

Object getRenderedStartForm(String processDefinitionId)

Rendered form generated by the default build-in form engine for starting a new process instance.

getRenderedStartForm

Object getRenderedStartForm(String processDefinitionId,
                            String formEngineName)

Rendered form generated by the given build-in form engine for starting a new process instance.

submitStartFormData

ProcessInstance submitStartFormData(String processDefinitionId,
                                    Map<String,String> properties)

Start a new process instance with the user data that was entered as properties in a start form.

submitStartFormData

ProcessInstance submitStartFormData(String processDefinitionId,
                                    String businessKey,
                                    Map<String,String> properties)

Start a new process instance with the user data that was entered as properties in a start form. A business key can be provided to associate the process instance with a certain identifier that has a clear business meaning. For example in an order process, the business key could be an order id. This business key can then be used to easily look up that process instance , see ProcessInstanceQuery.processInstanceBusinessKey(String). Providing such a business key is definitely a best practice. Note that a business key MUST be unique for the given process definition. Process instance from different process definition are allowed to have the same business key.

Parameters:

processDefinitionId - the id of the process definition, cannot be null.

businessKey - a key that uniquely identifies the process instance in the context or the given process definition.

properties - the properties to pass, can be null.

getTaskFormData

TaskFormData getTaskFormData(String taskId)

Retrieves all data necessary for rendering a form to complete a task. This can be used to perform rendering of the forms outside of the process engine.

getRenderedTaskForm

Object getRenderedTaskForm(String taskId)

Rendered form generated by the default build-in form engine for completing a task.

getRenderedTaskForm

Object getRenderedTaskForm(String taskId,
                           String formEngineName)

Rendered form generated by the given build-in form engine for completing a task.

submitTaskFormData

void submitTaskFormData(String taskId,
                        Map<String,String> properties)

Completes a task with the user data that was entered as properties in a task form.

saveFormData

void saveFormData(String taskId,
                  Map<String,String> properties)

Save the data that was entered as properties in a task form.

getStartFormKey

String getStartFormKey(String processDefinitionId)

Retrieves a user defined reference to a start form. In the Explorer app, it is assumed that the form key specifies a resource in the deployment, which is the template for the form. But users are free to use this property differently.

getTaskFormKey

String getTaskFormKey(String processDefinitionId,
                      String taskDefinitionKey)

Retrieves a user defined reference to a task form. In the Explorer app, it is assumed that the form key specifies a resource in the deployment, which is the template for the form. But users are free to use this property differently. Both arguments can be obtained from Task instances returned by any TaskQuery.
