Fedora Update Notification

2022-12-11 01:24:18.453204
--------------------------------------------------------------------------------

Name        : bcel
Product     : Fedora 37
Version     : 6.5.0
Release     : 3.fc37
URL         : https://commons.apache.org/proper/commons-bcel/
Summary     : Byte Code Engineering Library
Description :
The Byte Code Engineering Library (formerly known as JavaClass) is
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.

Summary

The Byte Code Engineering Library (formerly known as JavaClass) is

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.
