报价:

框架包含与众不同的关键区别功能，这些特征将它们与普通库分开:

控制反转:在框架中，与库或普通用户应用程序不同，整个程序的控制流不是由调用者决定，而是由框架决定.
默认行为:框架具有默认行为.此默认行为必须是一些有用的行为，而不是一系列的无操作.
可扩展性:用户通常可以通过选择性覆盖来扩展框架，也可以通过用户代码对其进行专门化以提供特定功能.
不可修改的框架代码:通常，在接受用户实现的扩展时，不应修改框架代码.换句话说，用户可以扩展框架，但不应修改其代码.

Frameworks contain key distinguishing features that separate them from normal libraries:

inversion of control: In a framework, unlike in libraries or normal user applications, the overall program''s flow of control is not dictated by the caller, but by the framework.
default behavior: A framework has a default behavior. This default behavior must be some useful behavior and not a series of no-ops.
extensibility: A framework can be extended by the user usually by selective overriding or specialized by user code to provide specific functionality.
non-modifiable framework code: The framework code, in general, is not supposed to be modified, while accepting user-implemented extensions. In other words, users can extend the framework, but should not modify its code.
