In this case, the restriction selects all resources that have an issue property where the value of that property is of class issue.
在这个例子里，约束条件选择所有具有issue特性并且该特性的值属于类issue的资源。
This restriction is lifted in Groovy; you can change the values of variables in a containing scope from within an anonymous inner class.
Groovy则消除了这种限制，在Groovy中，匿名内部类可以修改外部的变量值。
By its subclassing from this restriction, the RelevantResource class is a sort of virtual class that includes a set of all resources that meet the restriction.
通过从这一约束条件划分子类，RelevantResource类成为一种包含一个所有满足该约束条件资源集合的虚拟类。
Besides the distributional requirements, you are free to pursue your own interests. There is no restriction in your choice of subjects other than your major-such a flexibility in class shopping.
除了对课程分配方面的强制规定外，你可以随意选择自己感兴趣的科目，即便是对你专业以外的课程学院也没有任何限制。
In this paper, we consider the best approximation of a matrix under a given linear restriction with some fixed elements. This result can be apply to solving a class matrix inverse eigenvalue problem.
本文研究具有某些固定元素的矩阵在线性约束下的最佳逼近，其结果可以用于解一类矩阵反特征值问题。
