The Byte Code Engineering Library (Apache Commons BCEL) is
|
2002-05-06 19:41:11 +02:00
|
|
|
intended to give users a convenient possibility to analyze, create,
|
|
|
|
|
and manipulate (binary) Java class files (those ending with
|
|
|
|
|
.class). Classes are represented by objects which contain all the
|
|
|
|
|
symbolic information of the given class: methods, fields and byte code
|
|
|
|
|
instructions, in particular.
|
|
|
|
|
|
|
|
|
|
Such objects can be read from an existing file, be transformed by a
|
|
|
|
|
program (e.g. a class loader at run-time) and dumped to a file
|
|
|
|
|
again. An even more interesting application is the creation of classes
|
|
|
|
|
from scratch at run-time. The Byte Code Engineering Library (BCEL) may
|
|
|
|
|
be also useful if you want to learn about the Java Virtual Machine
|
|
|
|
|
(JVM) and the format of Java .class files.
|
|
|
|
|
|
|
|
|
|
BCEL is already being used successfully in several projects such as
|
|
|
|
|
compilers, optimizers, obsfuscators and analysis tools, the most
|
|
|
|
|
popular probably being the Xalan XSLT processor at Apache.
