+## Methods
+
+-   `onFormFieldChanged(field: FormFieldModel)`
+    Triggered when field is changed. Validates field and calls FormService
+-   `validateForm(): void`
+    Validates entire form and all form fields.
+-   `validateField(field: FormFieldModel): void`
+    Validates a specific form field, triggers form validation.
+-   `parseRootFields(json: any): (ContainerModel | FormFieldModel)[]`
+    Activiti supports 3 types of root fields: container|group|dynamic-table
+-   `loadData(formValues: FormValues)`
+    Loads external data and overrides field values. Typically used when form definition and form data coming from different sources
+-   `canOverrideFieldValueWithProcessValue(field: FormFieldModel, variableId: string, formValues: FormValues): boolean`
+    Checks if field value can be overriden with process value
+-   `isDefined(value: string): boolean`
+    Check if variable is defined
+-   `getFormVariable(identifier: string): FormVariableModel`
+    Returns a form variable that matches the identifier.
+-   `getDefaultFormVariableValue(identifier: string): any`
+    Returns a value of the form variable that matches the identifier. Provides additional conversion of types (date, boolean).
+-   `getProcessVariableValue(name: string): any`
+    Returns a process variable value. When mapping a process variable with a form variable the mapping is already resolved by the rest API with the name of variables.formVariableName.
+-   `parseValue(type: string, value: any): any`
+    Parse value data and boolean
+-   `hasTabs(): boolean`
+    Check if form has tabs
+-   `hasFields(): boolean`
+    Check if there are any fields
+-   `hasOutcomes(): boolean`
+    Check if form has outcomes
+-   `getFieldById(fieldId: string): FormFieldModel`
+    Find field by id
+-   `getFormFields(filterTypes?: string[]): FormFieldModel[]`
+    Get form fields
+-   `processFields(fields: (ContainerModel | FormFieldModel)[], formFieldModel: FormFieldModel[]): void`
+    Process fields
+-   `isContainerField(field: ContainerModel | FormFieldModel): field is ContainerModel`
+    Check if it is container
+-   `isSectionField(field: ContainerModel | FormFieldModel): field is FormFieldModel`
+    Check if it is section
+-   `handleSectionField(section: FormFieldModel, formFieldModel: FormFieldModel[]): void`
+    Handle section
+-   `handleContainerField(container: ContainerModel, formFieldModel: FormFieldModel[]): void`
+    Handle container
+-   `handleSingleField(field: FormFieldModel, formFieldModel: FormFieldModel[]): void`
+    Handle single field
+-   `filterFieldsByType(fields: FormFieldModel[], types?: string[]): FormFieldModel[]`
+    Filter fields based on type
+-   `markAsInvalid(): void`
+    Set form as invalid
+-   `parseOutcomes()`
+    Parse outcomes from json
+-   `addValuesNotPresent(valuesToSetIfNotPresent: FormValues)`
+    Set values if they are not present
+-   `isValidDropDown(key: string): boolean`
+    Validates dropdown
+-   `setNodeIdValueForViewersLinkedToUploadWidget(linkedUploadWidgetContentSelected: UploadWidgetContentLinkModel)`
+    Set node id
+-   `changeFieldVisibility(fieldId: string, visibility: boolean): void`
+    Changes field visibility
+-   `changeFieldDisabled(fieldId: string, disabled: boolean): void`
+    Changes disabled status of field
+-   `changeFieldRequired(fieldId: string, required: boolean): void`
+    Changes required status of field
+-   `changeFieldValue(fieldId: string, value: any): void`
+    Changes field value
+-   `changeVariableValue(variableId: string, value: any): void`
+    Changes variable value
+-   `loadInjectedFieldValidators(injectedFieldValidators: FormFieldValidator[]): void`
+    Checks it there are any injectedValidators and adds them to the array of field validators.
