      • getStartFormData

        public StartFormData getStartFormData​(String processDefinitionId)
        Description copied from interface: FormService
        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.
        Specified by:
        getStartFormData in interface FormService

      • 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:
        getTaskFormData 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.

        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

      • submitTaskFormWithVariablesInReturn

        public VariableMap submitTaskFormWithVariablesInReturn​(String taskId,

        Description copied from interface: FormService
        Completes a task with the user data that was entered as properties in a task form.
        Specified by:
        submitTaskFormWithVariablesInReturn in interface FormService
        deserializeValues - if false, returned SerializableValues will not be deserialized (unless they are passed into this method as a deserialized value or if the BPMN process triggers deserialization)
        Returns:
        a map of process variables

      • 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.
