What is meant by a composite state in a state machine diagram?
Understand the Problem
The question is asking for the definition of a composite state in the context of state machine diagrams, specifically, what characteristics define such a state.
Answer
A composite state has nested substates.
A composite state in a state machine diagram is a state that has substates, also known as nested states, which can be either sequential (disjoint) or concurrent (orthogonal).
Answer for screen readers
A composite state in a state machine diagram is a state that has substates, also known as nested states, which can be either sequential (disjoint) or concurrent (orthogonal).
More Information
Composite states help organize complex state machines by grouping related states, which can improve readability and manageability. They can represent different functionalities or roles within a larger process.
Tips
A common mistake is to confuse composite states with simple states or to neglect the use of regions for concurrent substates.
