委托模型
as with explicit class loading, if the class is already loaded, then a reference is simply returned; otherwise, the loader goes through the delegation model to load the class.
与显式类装入一样,如果类已经装入了,那么只是返回一个引用;否则,装入器会通过委托模型装入类。
in this case, the delegation model is a proper graph (with cycles), and so a deadlock can occur as a result of particular class relationships and thread usage.
在本例中,委托模型是一个正确的图(带有循环),所以死锁的发生可能是使用特定的类关系和线程的结果。
to realize bilateral protocols and dynamic restriction of roles mutex, and to solve the problems arose by permission sharing, a role-based dynamic delegation model was proposed.
为在转授权过程中实现双边协议和动态角色互斥约束,解决由权限共享引起的角色互斥问题,提出了基于角色的动态转授权模型。
this paper presented an agentbased flexible role delegation model based on rbac.
结合rbac模型,提出一种基于代理的灵活角色委托模型。
when it comes to developing a rich and interactive user interface, cocoa has always excelled. this is partly because of the flexible delegation model that it provides.
需要开发一个交互式富用户界面时,cocoa总是技高一筹,部分原因是它提供的灵活的代理模型。
these deadlocks can occur in multi-threaded environments when the usual delegation model is bypassed. consider the situation outlined in figure 1
这些死锁可以发生在多线程环境中当常用的委托模型被忽略时。
for administration of virtual portals, the delegation model of portal access control is leveraged.
对于虚拟门户的管理来说,利用了portal存取控制的委派模型。
of course, if the standard delegation model is required, then there is no need to override loadclass() in the first place.
当然,如果要求标準委托模型,那么不需要首先重载loadclass()。
if the class is already loaded, then a reference is simply returned; otherwise, the loader goes through the delegation model to load the class.
如果类已经装入,那么只是返回一个引用;否则,装入器会通过委托模型装入类。
because the identities of the deadlocked class loaders are known, it is possible to examine the delegation model that these class loaders are using.
因为死锁的类装入器的标识已知,所以可以检查这些类装入器使用的委托模型。
the class loader delegation model is the graph of class loaders that pass loading requests to each other.
类装入器委托模型是把装入请求相互传给对方的类装入器图。
by introducing the idea of using rbac itself to manage rbac, a new self-administrative delegation model apbdm is presented on the basis of pbdm, and its main idea and architecture are discussed.
在pbdm 代理模型的基础上,引入rbac自身管理rbac的思想,提出一种新的具有自我管理能力的授权代理模型apbdm。
the class loaders are listed with parents before children because of the way that the standard delegation model works: parents go first.
在列出类装入器的时候,父类在子女之前列出,因为标準的委托模型的工作方式是父类优先。
to satisfy various restricted delegation requirements of actual applications, on the basis of the existing works, a hierarchical role-based restricted delegation model (hrrdm) was proposed.
针对实际应用中对委托限制多方面需求的实际,在已有工作的基础上,提出了基于层次角色的受限委托模型hrrdm。
to adapt to the situation that a user could not complete the assigned task in time, a role-hierarchy-based task delegation model in workflow is proposed.

a delegation model also is presented by defining concepts such as authorization root delegation subject.
通过定义授权源、实体及委托等概念建立起基于信任度的多级分组授权委托模型。
