ASM

概述: 

ObjectWeb ASM轻量级的Java字节码处理框架。它可以动态生成二进制格式的stub类或其他代理类，或者在类被JAVA虚拟机装入内存之前，动态修改类。ASM 提供了与 BCEL和SERP相似的功能，只有22K的大小，比起350K的BCEL和150K的SERP来说，是相当小巧的，并且它有更高的执行效率，是BCEL的7倍，SERP的11倍以上。

官方:

ASM is an all purpose Java bytecode manipulation and analysis framework. It can be used to modify existing classes or dynamically generate classes, directly in binary form. Provided common transformations and analysis algorithms allow to easily assemble custom complex transformations and code analysis tools.

ASM offer similar functionality as other bytecode frameworks, but it is focused on simplicity of use and performance. Because it was designed and implemented to be as small and as fast as possible, it makes it very attractive for using in dynamic systems*.

(*) ASM can of course be used in a static way too.
