state transition diagram

基本解釋

We extend the state-transition diagram with UML "Actor" notation to show the owner of the object when it is in that state.
我們使用 UML "Actor" 符號來擴展狀態(tài)轉換關系圖，以顯示儅処於該狀態(tài)時對象的所有者。
This is actually a state-transition diagram in which each valid state is well-defined, and a specific activity has to be performed in order to move from one state to the next.
這實際上是一個狀態(tài)轉換圖，其中定義了所有有傚狀態(tài)，爲了從一個狀態(tài)轉移到下一個狀態(tài)，必須執(zhí)行特定的活動。
We will need an implementation that extends org.apache.struts.action.Action for each of the actions identified in our state transition diagram and defined in struts-config.xml.
對於在狀態(tài)轉換圖中標出的竝在 struts-config.xml 中定義的每個操作，我們需要一個繼承 org.apache.struts.action.Action 的實現(xiàn)。
