ASM is an all purpose Java bytecode manipulation and analysis framework.

ASM is an all purpose Java bytecode manipulation and analysis framework. It can be used to modify existing classes or to dynamically generate classes, directly in binary form. ASM provides some common bytecode transformations and analysis algorithms from which custom complex transformations and code analysis tools can be built. ASM offers similar functionality as other Java bytecode frameworks, but is focused on performance. Because it was designed and implemented to be as small and as fast as possible, it is well suited for use in dynamic systems (but can of course be used in a static way too, e.g. in compilers).

Market Readiness Synthesis

Created by Eric Bruneton in 2000, during his PhD at Inria, ASM is one of the most popular projects in the OW2 code base. The project is well recognized and broadly used by the Java programmer community. The code is super stable and super proven and needs to evolve only as to remain aligned with the evolutions of the Java standard. A true community project, ASM is not promoted by professional sales nor supported by commercial support plans. However the community of users is sufficiently large so as to provide answers to any question on its mailing list.
