Data Flow Icons

Two types of flow lines are allowed in statecharts: data flow lines, drawn as solid arrows, and control flow lines, drawn as dashed arrows. Typically, data flow lines carry information that is used in computations and data-processing operations.

Note: Default transitions do not have a source state and do not support triggers.
 
Create Transition - creates an event that makes the model leave one state and enter another. You label each transition with the trigger that causes it to be taken and, optionally, with an action. Separate the trigger from the action with a slash.
Label Existing Transition - allows you to name a flow line that denotes either a single information element that flows along the line or a group of such elements.
Create Default Transition - establishes a control flow between two activities. Control flow lines carry information or signals that are used in making control decisions, for example, commands or synchronization messages.
Create And-Line - divides a state into orthogonal (or parallel) components.
