Initial state (dictionary item)
For automation interface information about an Initial State, see State (automation interface). For automation interface purposes, an Initial State is a State that has its UML State Type set to Initial.
An Initial State indicates the point from which a Transition leads an object to the state it acquires at instantiation. A Class or Interface can have multiple Initial States depending on the events causing instantiation.
Create an Initial State through a Modeler explorer pane or a State Diagram:
• In a Modeler pane, right-click a State Machine or Sequential State, and select New > Pseudo State > Initial State.
• On a State Diagram, click the Initial State button, and then click the diagram background (within the frame) or within a Sequential State.
When used on a State Diagram, an Initial State's notation is as follows.
The View Options on a State Diagram allow you to show or hide the Name. By default, the Name is not shown. See Initial state view options - state diagram.
On a State Diagram, you can populate Initial States: right-click the State Machine (frame) or Sequential State that owns the Initial States, and select Populate > All States. Note that all owned states are added to the diagram.
In the Dictionary pane, Initial States are listed in the UML\States folder.
In the Modeler panes, a short-cut symbol on the Initial State's icon indicates that the item is a stub.
The following sections provide information about how an Initial State is used in the model.
Properties
An Initial State has only the standard properties.

Constraint
Dependency — The Dependency is owned jointly by the Initial State and the other associated item. The access permissions you have to a Dependency are determined by the access permissions of the dependent item.
Transition — The Transition is owned jointly by the Initial State and the other associated item. The access permissions you have to a Transition are determined by the access permissions of the source item.
