The state diagram in the Unified Modeling Language is essentially a Harel statechart with standardized notation〔(【引用サイトリンク】 author = OMG )〕 ,〔D. Drusinsky, (''Modelling and verification using UML statecharts'' ), Elsevier, 2006〕 which can describe many systems, from computer programs to business processes. In UML 2 the name has been changed to ''State Machine Diagram''. The following are the basic notational elements that can be used to make up a diagram: * Filled circle, representing to the initial state * Hollow circle containing a smaller filled circle, indicating the final state (if any) * Rounded rectangle, denoting a state. Top of the rectangle contains a name of the state. Can contain a horizontal line in the middle, below which the activities that are done in that state are indicated * Arrow, denoting transition. The name of the event (if any) causing this transition labels the arrow body. A guard expression may be added before a "/" and enclosed in square-brackets ( ''eventName'' * Thick horizontal line with either x>1 lines entering and 1 line leaving or 1 line entering and x>1 lines leaving. These denote join/fork, respectively. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「State diagram (UML)」の詳細全文を読む スポンサード リンク
