Stateflow

Using Dot Notation with Properties and Methods

You can access the properties and methods of an object by adding a period (.) and the name of the property or method to the end of an object's handle variable. For example, the following command returns the Type property for a State object represented by the handle s:

• stype = s.Type
  

The following command calls the dialog method of the State object s to open a properties dialog for that state:

• s.dialog
  

Nesting Dot Notation

You can nest smaller dot expressions in larger dot expressions of properties. For example, the Chart property of a State object returns the Chart object of the containing chart. Therefore, the expression s.Chart.Name returns the name of the chart containing the State whose object is s.

Methods can also be nested in dot expressions. For example, if the State object sA1 represents state A1 in the final Stateflow chart at the end of Create New Objects in the Chart, the following command returns the string label for state A1's inner transition to its state A11.

• label = sA1.innerTransitionsOf.LabelString
  

The preceding command uses the LabelString property of a Transition object and the innerTransitions method for a State object. It works as shown only because state A1 has one inner transition. If state A1 has more than one transition, you must first find all the inner transitions and then use an array index to access each one, as shown below:

• innerTransitions = sA1.innerTransitionsOf
  label1 = innerTransitions(1).LabelString
  label2 = innerTransitions(2).LabelString
  and so on...
