How do you do a state machine in C++?

How do you do a state machine in C++?

Creating a new state machine requires a few basic high-level steps:

  1. Inherit from the StateMachine base class.
  2. Create a States enumeration with one entry per state function.
  3. Create state functions using the STATE macros.
  4. Optionally create guard/entry/exit functions for each state using the GUARD , ENTRY and EXIT macros.

What is state machine coding?

A state machine is a programming architecture that allows dynamic flow to states depending on values from previous states or user inputs. This architecture is suitable for applications that can be described as a combination of: States. Decision-making logic that determines when to move to a particular state.

How do you build a state machine?

Creating a state machine

  1. In the Project Explorer, right-click the model and select Add UML > Package.
  2. Enter a name for the new package. For example, Finite State Machines.
  3. Right-click the package and select Add UML > State Machine.
  4. Enter a name for the new state machine. For example, FTM State Machine.

How do I create an FSM file?

  1. Switch to the Modeling perspective.
  2. Click File > New > Model Project.
  3. Provide a name for the project.
  4. Click Next.
  5. Select FTM in the Categories: list and Blank FTM FSM Model in the Templates: list.
  6. Enter a file name for the model.
  7. Click Next.

How do you do a state machine?

How do you write a state diagram?

Steps to draw a state diagram –

  1. Identify the initial state and the final terminating states.
  2. Identify the possible states in which the object can exist (boundary values corresponding to different attributes guide us in identifying different states).
  3. Label the events which trigger these transitions.

How do you create a model state machine diagram?

How to Draw a State Machine Diagram?

  1. A unique and understandable name should be assigned to the state transition that describes the behavior of the system.
  2. Out of multiple objects, only the essential objects are implemented.
  3. A proper name should be given to the events and the transitions.

How do you write a state transition table?

A transition table is represented by the following things:

  1. Columns correspond to input symbols.
  2. Rows correspond to states.
  3. Entries correspond to the next state.
  4. The start state is denoted by an arrow with no source.
  5. The accept state is denoted by a star.
