Um\u00a0<\/span>estado<\/span><\/strong>\u00a0\u00e9 uma condi\u00e7\u00e3o ou situa\u00e7\u00e3o no curso da vida de um objeto durante a qual ele satisfaz alguma condi\u00e7\u00e3o, realiza alguma atividade ou espera por algum evento.\u00a0Um objeto permanece em um estado por um per\u00edodo limitado de tempo.<\/span><\/p>\n

Por exemplo, um\u00a0<\/span>Aquecedor<\/span>\u00a0em uma casa pode estar em qualquer um dos quatro estados: (1)\u00a0<\/span>Idle<\/span>\u00a0(esperando<\/span>
\npor um comando para iniciar o aquecimento da casa), (2)\u00a0<\/span>Ativando<\/span>\u00a0(seu g\u00e1s est\u00e1 ligado, mas est\u00e1 esperando chegar<\/span>
\n\u00e0 temperatura ), (3)\u00a0<\/span>Ativo<\/span>\u00a0(o g\u00e1s e o ventilador est\u00e3o ambos ligados) e (4)\u00a0<\/span>Desligando<\/span>\u00a0(o g\u00e1s est\u00e1 desligado, mas<\/span>
\no ventilador est\u00e1 ligado, liberando o calor residual do sistema).<\/span><\/p>\n

Uma\u00a0<\/span>transi\u00e7\u00e3o<\/span><\/strong>\u00a0\u00e9 um relacionamento entre dois estados indicando que um objeto no primeiro estado<\/span>

\nas condi\u00e7\u00f5es especificadas forem satisfeitas.\u00a0Em tal mudan\u00e7a de estado, diz-se que a transi\u00e7\u00e3o \u00e9 disparada.\u00a0At\u00e9 que a transi\u00e7\u00e3o<\/span>
\nseja acionada, diz-se que o objeto est\u00e1 no estado de origem;\u00a0depois de disparado, diz-se que est\u00e1 no estado alvo.<\/span><\/p>\n

Por exemplo, um Aquecedor pode fazer a transi\u00e7\u00e3o do estado\u00a0<\/span>Idle<\/span>\u00a0para o estado Ativando quando<\/span>
\nocorre um evento como tooCold (com o par\u00e2metro desejadoTemp).<\/span><\/p>\n
