This is similar to using an abstract pointcut , where subaspects must override the pointcut to apply advice 這與使用一個抽象切點類似,其中子方面必須覆蓋切點以使用建議。
Enzyme cutting analysis indicated that they had different enzyme cutting sites and cutting site number 利用常見的限制性內切酶酶切分析表明,二者有不同的酶切位點和切點數(shù)。
With an aop implementation , these could be published as four pointcuts that could be combined and refined in any way desired 使用aop實現(xiàn),它們可以發(fā)布為四個可以隨意組合和修飾的切點。
The abstract operation monitor also provides pointcuts with concrete advice that define common ways to monitor requests 在抽象操作監(jiān)視器中,還提供了具有具體建議的切點,它定義了監(jiān)視請求的常用方法。
To avoid overmany crossings of fw layers , which reduce the using of the filament strength , the number of the tangency points is chosen to one 為了避免fw層的交叉點過多而影響纖維強度的發(fā)揮,所選擇的切點數(shù)為1個。
For example , you could define a more narrow pointcut for monitoring struts actions in an xml - defined aspect and exclude the standard 例如,可以定義一個更狹窄的切點以監(jiān)視在一個xml定義的方面中的struts操作,并排除標準的
Having an empty default implementation for a template pointcut like this is quite similar to having an empty default implementation for a template method 像這樣的模板切點有一個空的默認實現(xiàn)與模板方面有一個空的默認實現(xiàn)很相像。
You can often write pointcuts this way by only using class names in a statically resolvable context such as in a field signature or type pattern 只需在像字段簽名或者類型模式這樣的靜態(tài)可解析的上下文中使用類名就可得到這樣的切點。
And or pointcuts to identify business relationships from the annotations for example , determining object aggregation from cascading persistent data 和/或切點從注釋中標識業(yè)務關系更具吸引力(例如,從級聯(lián)持久化數(shù)據確定對象聚合) 。
