Stateflow

Stateflow Diagram Objects

This section describes most of the graphical and nongraphical objects in a Stateflow diagram along with the concepts that relate them. The subsections are as follows:

• Graphical Objects Example Diagram -- Presents an example display of the key graphical objects in a Stateflow diagram.
• States -- Describes the role of states in a Stateflow diagram that represent the current mode of an executing diagram.
• Transitions -- Describes the role of a transitions in a Stateflow diagram that provide a path for an executing diagram to change from one mode (state) to another.
• Default Transitions -- Describes the role of a default transition that specifies which exclusive (OR) state in an executing diagram is active on startup.
• Events -- Describes the role of events that drive Stateflow diagram execution.
• Data -- Describes the role of data that serve as variables in a Stateflow diagram.
• Conditions -- Describes the conditions that, along with events, drive Stateflow diagram execution.
• History Junction -- Describes the role of history junctions that record the most recently active substate of a chart or superstate.
• Actions -- Describes the role of actions that take place as part of Stateflow diagram execution.
• Connective Junctions -- Describes the role of connective junctions that provide decision points for transitions taking place during diagram execution.

All Stateflow objects are arranged in a hierarchy of objects. See Stateflow Hierarchy of Objects.
