To model inheritance on a class diagram , a solid line is drawn from the child class the class inheriting the behavior with a closed , unfilled arrowhead or triangle pointing to the super class 為了在一個(gè)類圖上建模繼承,從子類(要繼承行為的類)拉出一條閉合的,單鍵頭(或三角形)的實(shí)線指向超類。
For instance , a small orange triangle pointing to the orange triangle with a heavy border line as the target object means the originating web service in a short run is interacting with the long - running target service or application . it can also point to an eai application that in turn interacts with a non - web service or another eai application 例如,一個(gè)小的橙色三角指向一個(gè)深顏色邊界的橙色三角說明發(fā)起web服務(wù)是一個(gè)短暫運(yùn)行的web服務(wù),它與一個(gè)長(zhǎng)期運(yùn)行的目標(biāo)服務(wù)或應(yīng)用程序進(jìn)行交互,它還可以指向一個(gè)eai應(yīng)用程序,這個(gè)應(yīng)用程序反過來又可以與其它非web服務(wù)或其它應(yīng)用程序進(jìn)行交互。
