That notation does not exist in UML. 该表示法在UML中不存在。
It might mean something in another notation, but then of course it would be helpful to know which one. 这可能意味着用另一种表示法表示某些内容，但是当然知道哪个表示会有所帮助。

Was it like this ? 像这样吗？
If so, it means that class A has a data member (a) which is of type B. This is a simple association relationship such that an object of type A refers to an object of type B using a variable 'a' 如果是这样，则意味着类A具有类型为B的数据成员（a）。这是一种简单的关联关系，因此类型A的对象使用变量'a'引用类型B的对象。
If the head of the arrow was hollow, it means A is a subtype of B. If the line connecting A and B is dashed, it means class A implements interface B. ...etc. 如果箭头的头部是空心的，则表示A是B的子类型。如果连接A和B的线是虚线，则表示A类实现了接口B。
UML is a pretty exacting graphical format, so the small details may make big differences in meaning. UML是一种相当严格的图形格式，因此小的细节可能会在含义上产生很大的差异。
It might be better if you can get a picture and upload it, then we can help you with the meaning. 如果您可以获取图片并上传，可能会更好，然后我们可以为您提供帮助。
