getTaskFormData

public TaskFormData getTaskFormData(String taskId)

Description copied from interface: FormService

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.

Specified by:

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

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

submitStartForm

public ProcessInstance submitStartForm(String processDefinitionId,
                                       Map<String,Object> properties)

Description copied from interface: FormService

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

Specified by:

submitStartForm in interface FormService

submitStartForm

public ProcessInstance submitStartForm(String processDefinitionId,
                                       String businessKey,
                                       Map<String,Object> properties)

Description copied from interface: FormService

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.

Specified by:

submitStartForm in interface FormService

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.

submitTaskFormData

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

Specified by:

submitTaskFormData in interface FormService

submitTaskForm

public void submitTaskForm(String taskId,
                           Map<String,Object> properties)

Description copied from interface: FormService

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

Specified by:

submitTaskForm in interface FormService

getStartFormKey

public String getStartFormKey(String processDefinitionId)

Description copied from interface: FormService

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.

Specified by:

getStartFormKey in interface FormService

getTaskFormKey

public String getTaskFormKey(String processDefinitionId,
                             String taskDefinitionKey)

Description copied from interface: FormService

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.

Specified by:

getTaskFormKey in interface FormService

getStartFormVariables

public VariableMap getStartFormVariables(String processDefinitionId)

Description copied from interface: FormService

Retrieves a list of all variables for rendering a start from. The method takes into account FormData specified for the start event. This allows defining default values for form fields.

Specified by:

getStartFormVariables in interface FormService

Parameters:

processDefinitionId - the id of the process definition for which the start form should be retrieved.

Returns:

a map of VariableInstances.

getStartFormVariables

public VariableMap getStartFormVariables(String processDefinitionId,
                                         Collection<String> formVariables,
                                         boolean deserializeObjectValues)

Description copied from interface: FormService

Retrieves a list of requested variables for rendering a start from. The method takes into account FormData specified for the start event. This allows defining default values for form fields.

Specified by:

getStartFormVariables in interface FormService

Parameters:

processDefinitionId - the id of the process definition for which the start form should be retrieved.

formVariables - a Collection of the names of the variables to retrieve. Allows restricting the set of retrieved variables.

deserializeObjectValues - if false object values are not deserialized

Returns:

a map of VariableInstances.

getTaskFormVariables

public VariableMap getTaskFormVariables(String taskId)

Description copied from interface: FormService

Retrieves a list of all variables for rendering a task form. In addition to the task variables and process variables, the method takes into account FormData specified for the task. This allows defining default values for form fields.

A variable is resolved in the following order:

• First, the method collects all form fields and creates variable instances for the form fields.
• Next, the task variables are collected.
• Next, process variables from the parent scopes of the task are collected, until the process instance scope is reached.

Specified by:

getTaskFormVariables in interface FormService

Parameters:

taskId - the id of the task for which the variables should be retrieved.

Returns:

a map of VariableInstances.

getTaskFormVariables

public VariableMap getTaskFormVariables(String taskId,
                                        Collection<String> formVariables,
                                        boolean deserializeObjectValues)

Description copied from interface: FormService

Retrieves a list of requested variables for rendering a task form. In addition to the task variables and process variables, the method takes into account FormData specified for the task. This allows defining default values for form fields.

A variable is resolved in the following order:

• First, the method collects all form fields and creates variable instances for the form fields.
• Next, the task variables are collected.
• Next, process variables from the parent scopes of the task are collected, until the process instance scope is reached.

Specified by:

getTaskFormVariables in interface FormService

Parameters:

taskId - the id of the task for which the variables should be retrieved.

formVariables - a Collection of the names of the variables to retrieve. Allows restricting the set of retrieved variables.

deserializeObjectValues - if false object values are not deserialized

Returns:

a map of VariableInstances.
