如何定义直接关联

Question

根据下面的代码，你能告诉我如何(如果可能的话)从类Service中引用类ComputationUnit中定义的数组吗?

class ComputationUnit {
    contains Method[1..*] methods 
}
class Method {
    String name
    String signature
    Object sourceCode
    contains Parameter[1..*] parameters
}
class Servic e {
    contains Comment comment
    contains Parameter[1..*] parameters
    contains Contract[0..*] contracts
    refers Method[] methods //How can I refer to the array defined inside the ComputationUnit class?
}

Answer 1

你不能。这说不通啊。在ComputationUnit类中不仅定义了一个数组，在ComputationUnit的每个实例中都定义了一个数组。您需要哪个实例?

你应该这样写:

refers ComputationUnit unit

，然后根据需要从引用到单元访问数组
