Properties and Methods Sorted by Stateflow Object

The following reference tables for Stateflow^® API properties and methods have these columns:

Name — The name of the property or method. To access or set a property value or to call a method, use its name in dot notation along with a Stateflow object. Properties with multiple levels of hierarchy (such as the LoggingInfo and Props properties of data objects) must be set individually. For more information, see Access Properties and Methods of Stateflow Objects.
Type — The data type for the property. Some property types are other Stateflow API objects. For example, the Machine property of an object is the Stateflow.Machine object that contains the object.
Access — An access type for the property.
- RW (read/write): You can access or set the value of these properties by using the Stateflow API.
- RO (read-only): These properties are set by the Stateflow software.
Description — A description of the property or method.
