工作总结(2010-01)

2010-01-29 这个月把软件设计模式，粗略的地研究一遍。软件设计,不光光只是会点编码、用一用软件、然后在人前显耀下。23种desgin,是其它软件设计的基础，也是面象对象的基础。j2ee，很多模式都是基于这23种。 月未了，尽管，还不能完全软件设计模式完全应用起了，总结下，很好~ 2010-01-08 singleton/adapter/command/interpertor/chain of responsibily 2010-01-06 单键模式->内存自动释放->通用模板 静态成员初始化->模板静态成员初始化 2010-01-04 设计模式学习：练武也有章可循，然招式是死的，人是活的，活学活用这很重要。模式并不在于你了解多少，而在于撑握多少，能用于实际工作当中有多少。oo思想，目前达不到自然抽象，自然抽象变化很多，要达到完全智能，目前不可能。下面为GOF模式简单描述。 Creational Patterns Abstract Factory Creates an instance of several families of classes Builder Separates object construction from its representation Factory Method Creates an instance of several derived classes Prototype A fully initialized instance to be copied or cloned Singleton A class of which only a single instance can exist Structural Patterns Adapter Match interfaces of different classes Bridge Separates an object’s interface from its implementation Composite A tree structure of simple and composite objects Decorator Add responsibilities to objects dynamically Facade A single class that represents an entire subsystem Flyweight A fine-grained instance used for efficient sharing Proxy An object representing another object Behavioral Patterns Chain of Resp. A way of passing a request between a chain of objects Command Encapsulate a command request as an object Interpreter A way to include language elements in a program Iterator Sequentially access the elements of a collection Mediator Defines simplified communication between classes Memento Capture and restore an object's internal state Observer A way of notifying change to a number of classes State Alter an object's behavior when its state changes Strategy Encapsulates an algorithm inside a class Template Method Defer the exact steps of an algorithm to a subclass Visitor Defines a new operation to a class without change
