Visual Workflow

Visual Workflow allows administrators to build applications, known as flows, that guide users through screens for collecting and updating data.

For example, you can use Visual Workflow to script calls for a customer support center or to generate real-time quotes for a sales organization. You can embed a flow in a Visualforce page and access it in a Visualforce controller using Apex.

You can retrieve flow variables for a specific flow in Apex. The Flow.Interview Apex class provides the getVariableValue method for retrieving a flow variable, which can be in the flow embedded in the Visualforce page, or in a separate flow that is called by a subflow element. This example shows how to use this method to obtain breadcrumb (navigation) information from the flow embedded in the Visualforce page. If that flow contains subflow elements, and each of the referenced flows also contains a vaBreadCrumb variable, the Visualforce page can provide users with breadcrumbs regardless of which flow the interview is running.
