ASM also provides * a {@link org.objectweb.asm.ClassWriter ClassWriter} class, which is * a visitor that generates Java class files. * <p> * In order to generate a class from scratch, only the {@link * org.objectweb.asm.ClassWriter ClassWriter} class is necessary. Indeed, * in order to generate a class, one must just call its visit<i>XXX</i> * methods with the appropriate arguments to generate the desired fields * and methods. See the "helloworld" example in the ASM distribution for * more details about class generation. * <p> * In order to modify existing classes, one must use a {@link * org.objectweb.asm.ClassReader ClassReader} class to analyze * the original class, a class modifier, and a {@link org.objectweb.asm.ClassWriter * ClassWriter} to construct the modified class. The class modifier * is just a {@link org.objectweb.asm.ClassVisitor ClassVisitor} * that delegates most of the work to another {@link org.objectweb.asm.ClassVisitor * ClassVisitor}, but that sometimes changes some parameter values, * or call additional methods, in order to implement the desired * modification process. In order to make it easier to implement such * class modifiers, ASM provides the {@link org.objectweb.asm.ClassAdapter * ClassAdapter} and {@link org.objectweb.asm.MethodAdapter MethodAdapter} * classes, which implement the {@link org.objectweb.asm.ClassVisitor ClassVisitor} * and {@link org.objectweb.asm.MethodVisitor MethodVisitor} interfaces by * delegating all work to other visitors. See the "adapt" example in the ASM * distribution for more details about class modification. * <p> * The size of the core ASM library, <tt>asm.jar</tt>, is only 42KB, which is much * smaller than the size of the * <a href="http://jakarta.apache.org/bcel">BCEL</a> library (504KB), and than the * size of the * <a href="http://serp.sourceforge.net">SERP</a> library (150KB). ASM is also * much faster than these tools. Indeed the overhead of a load time class * transformation process is of the order of 60% with ASM, 700% or more with BCEL, * and 1100% or more with SERP (see the <tt>test/perf</tt> directory in the ASM * distribution)! * @since ASM 1.3 */ package org.powermock.api.mockito.repackaged.asm;
