Package org.apache.bcel.util

package org.apache.bcel.util

Utility classes for the Apache Byte Code Engineering Library (BCEL), namely:

• Collection classes for JavaClass objects
• A converter for class files to HTML
• A tool to find instructions patterns via regular expressions
• A class to find classes as defined in the CLASSPATH
• A class loader that allows to create classes at run time
