Java Reflection is often a confusing subject. the new comers to Java often feel it is difficult to understand. I will explain you the Reflection with simple example

Topics Covered

Java Reflection A few basics Reflection’s value proposition Enter George the programmer Choosing reflection ? Programming a reflective solution Examining running programs Finding a method at runtime Representing types with class objects Representing primitive types ? Representing interfaces Representing array types Understanding method objects Using dynamic invocation ? Using primitives with dynamic invocation ? Avoiding invocation pitfalls Diagramming for reflection Navigating the inheritance hierarchy Introspecting the inheritance hierarchy ? Exposing some surprises ? Another reflective circularity Recap Accessing fields reflectively Serializing objects Serializing to XML ? Choosing reflection Designing serialization with reflection Finding fields at runtime Understanding field objects Getting and setting field values Examining modifiers Introducing Member ? Interface introspection pitfall Introspecting for instance variables Accessing nonpublic members Working with arrays Serialization: putting it all together Serializing each component ? Serializing instance variables Using reflective serialization Recap Dynamic loading and reflective construction George’s deployment problem Designing with patterns ? Programming a reflective solution Enhancing the factory method with reflection ? Combining benefits of delegation and reflection Loading classes dynamically Basics of forName ? Getting array classes Primitives and forName Constructing objects reflectively Reflective construction basics ? Using constructor objects Constructing arrays reflectively Designing for dynamic loading Disadvantages of reflective construction with arguments Initializing through an interface Implementing deserialization Initiating deserialization ? Constructing the instances Restoring the object structure George’s serialization: limitations No interaction with readObject or writeObject ? No handling of final instance variables ? Only no-argument constructors No handling of illegal XML characters ? Performance Recap Using Java’s dynamic proxy Working with proxies George’s tracing problem Exploring Proxy Understanding invocation handlers Handling the methods of Object Implementing a tracing proxy A note on factories Chaining proxies Structuring invocation handlers for chaining ? Implementing a synchronized proxy ? Chaining the two proxies Stubbing interfaces for unit testing Examining stubs ? Design for stubbing with Proxy Implementation of stubbing with Proxy Generating SOAP remote proxies Pitfalls of using Proxy Recap Call stack introspection George’s logging problem Performing call stack introspection Logging with call stack introspection Pitfalls Class invariant checking Recap Using the class loader George’s test problem Essentials of ClassLoader Understanding the delegation model ? Programming a simple class loader ? Reinitializing static fields: a solution Multiple namespaces Dynamic class replacement Designing for replacement ? Implementing replacement Simplifying assumptions Additional considerations Security ? Don’t reinvent the wheel ? Modifying bytecode in a class loader ? When not to invent a specialized class loader Additional examples ? Endorsed Standards Override Recap Reflective code generation Reflective code generation Generating HelloWorldjava Class-to-class transformation framework CC ? Args ? CCConstructor CCTransformation Example: extent management CIdentitySubclassOfC and its subclasses UQueue Using the framework Relation to Aspect-Oriented Programming Recap Design patterns Singleton Decorator class-to-class transformations Proxy (again) Another composition feature Problematic issues in writing class-to-class transformations Recap Evaluating performance Evaluating performance Categorizing performance impact Using microbenchmarks Benchmarking two ways to use Proxy Understanding Amdahl’s Law Applying Amdahl’s Law Recap Reflecting on the future Looking forward: Java JSR —Generics ? JSR —Annotation Facility JSR —Language extensions Impact of Java on reflective code competition for Java reflection C# ? Python ? Smalltalk ? CLOS Ruby ? Perl Aspect-Oriented Programming your career
