Literal and expression modes overview
In Architect, the flow author has access to a variety of options to help build customized actions in the flow. Some actions, as well as the audio sequence dialog box, include specific fields that require authors to build calculations or expressions. Flow authors can configure these fields in literal or expression mode.
- In literal mode, Architect may offer pre-defined options such as True or False radio buttons or + and – spin control selection to help define a value, and more. You can also enter simple values manually, such as text-to-speech or attribute values. By default, Architect presents call flow actions in literal mode.
- In expression mode, Architect offers a robust set of tools that helps simplify the editing experience, including type-ahead functionality, built-in Expression Help, on-screen troubleshooting, and validation. Use expression editing to build complex calculations by entering and evaluating variables and operators. Additionally, some expression fields include an option for the Edit Expression dialog box, also known as the large expression editor, where you can access additional resources for the more complex expressions.
Before you begin, you should have a clearly defined outline of the process you want to create.
