Element: End state An end state is a pseudo state. It indicates that the execution of the area that contains this end state has ended. End states can be located in a statechart at the top level, in co
Element: State A state is the main element of a statechart. A state machine (or statechart) runs through various states during its runtime and executes their actions. A state can have ENTRY, DO, and E
Element: Composite state You can use this element to group multiple states together. . A composite state can be orthogonal or non-orthogonal. Orthogonal state: Composite state with two or more regions
Element: Fork/Join The fork is a pseudo state to split transitions to pseudo-parallel processing in orthogonal states. All transitions that originate from a fork are completion transitions that have t
Element: Choice A choice is a node in a statechart. The subsequent guard conditions are evaluated at the node within a cycle. It has at least one incoming transition and one outgoing transition. Choic
Element: Transition A transition controls the transition behavior between states. . A transition is possible when one of the following events occurs: Conditional event or change event Completion event
Coffee Machine The following application example illustrates the statechart of a coffee machine. It completely describes its process flow, determining how the machine behaves at runtime. See the sampl
