In the following example, two FlowStep elements are used to execute two activities in sequence. To model a basic sequence in which two activities execute in turn, the FlowStep element is used. Creating a basic activity sequence with a FlowStep node Types of flowchart elements include:įlowStep - Models one step of execution in the flowchart.įlowDecision - Branches execution based on a Boolean condition, similar to If.įlowSwitch – Branches execution based on an exclusive switch, similar to Switch.Įach link has an Action property that defines a ActivityAction that can be used to execute child activities, and one or more Next properties that define which element or elements to execute when the current element finishes execution. Types of flow nodesĭifferent types of elements are used depending on the type of flow control required when the element executes. Flowcharts also contain flow control elements such as FlowDecision and FlowSwitch that direct execution between contained activities based on the values of variables. ![]() Flowchart workflow structureĪ Flowchart activity is an activity that contains a collection of activities to be executed. The Flowchart activity is typically used to implement non-sequential workflows, but can be used for sequential workflows if no FlowDecision nodes are used. A flowchart is a well-known paradigm for designing programs.
