What is ASM: ASM is an open source java library for manipulating java byte code. So it has the same purpose as Apache BCEL. As this article assumes that the reader has some knowledge of java class file format, it is advisable to read about it in here. So how is it different from BCEL? Well firstly it allows for an event driven way to manipulate byte code eliminating the need to load the whole class in the memory just to make a small addition. Secondly, it does not have a separate class for every single instruction. Instead, it handles opcodes directly and only has constants representing each. This reduces the size of the library to a great extent. So, ASM is simply lighter and smarter. However, ASM also has a mechanism to deal with class files by loading the whole class into the memory just in case the operation is too complex to be handled through event based processing.

The current stable version of ASM is 3.3. However version 4.0 RC2 is out. So, I am going to discuss that version here.

Event based processing vs in memory processing: ASM supports both event driven and in memory processing. Event driven processing is lightweight, but is a little limiting. On the other hand, in memory processing is more flexible and easy to use, but it is more heavy weight. The in memory processor internally uses the event driven processor, just like the DOM XML parser internally uses the SAX XML parser.

The following program demonstrates listening to class processing events.

ASMHelloWorld.java

             */
            @Override

            }

                return super.visitAnnotation(desc, visible);
            }

            /**

            }

            /**

            @Override

                    String innerName, int access) {
                System.out.println("Inner Class: "+ innerName+" defined in "+outerName);
                super.visitInnerClass(name, outerName, innerName, access);
            }
            
            /**

            @Override

                    String desc, String signature, Object value) {
                System.out.println("Field: "+name+" "+desc+" value:"+value);
                return super.visitField(access, name, desc, signature, value);
            }

            
            @Override

                System.out.println("Method ends here");

            @Override

                System.out.println("Method: "+name+" "+desc);
                return super.visitMethod(access, name, desc, signature, exceptions);
            }

            /**

            @Override
            public void visitSource(String source, String debug) {
                System.out.println("Source: "+source);
                super.visitSource(source, debug);
            }
            
            
        };
        InputStream in=ASMHelloWorld.class.getResourceAsStream("/java/lang/String.class");
        ClassReader classReader=new ClassReader(in);
        classReader.accept(cl, 0);

    }

}

The above program does not do anything except printing what event is reached when. At this time, we are visiting the class java.lang.String. Note that in a java class, there is an order in which things appear. For example, methods always appear after the field. The events also occur in the same order. For more information, go through the class file format discussed in here.

The code itself is very straight forward, and does not need a lot of explanation. We first extend the class ClassVisitor and override the necessary methods. Then we set up a ClassReader and call its accept method passing the object of the ClassVisitor as a parameter.

New in version 4: Upto version 3.3, ClassVisitor was an interface, so we had to implement all the methods. To relieve the developer from this mess, there was ClassAdapter which had no op implementations of all methods, which the developer could extend. In version 4, ClassVisitor has become a class and ClassAdapter is no longer there.

Notice that some visitor methods return objects of other methods. The methods of those Visitor objects are called when the particular kind of object is traversed. The following example shows how to use a MethodVisitor to step through the method’s code.

DemoClassIntructionViewer.java

package com.geekyarticles.asm;

import java.io.InputStream;

import org.objectweb.asm.ClassReader;
import org.objectweb.asm.ClassVisitor;
import org.objectweb.asm.ClassWriter;
import org.objectweb.asm.MethodVisitor;
import org.objectweb.asm.Opcodes;
import org.objectweb.asm.commons.InstructionAdapter;

public class DemoClassInstructionViewer {

    public static class MethodPrinterVisitor extends ClassVisitor{

        public MethodPrinterVisitor(int api, ClassVisitor cv) {
            super(api, cv);
        }

        
        public MethodPrinterVisitor(int api) {
            super(api);
        }


        @Override
        public MethodVisitor visitMethod(int access, String name, String desc,
                String signature, String[] exceptions) {
            
            System.out.println("\n"+name+desc);
            
            MethodVisitor oriMv= new MethodVisitor(4) {
            };
            //An instructionAdapter is a special MethodVisitor that
            //lets us process instructions easily
            InstructionAdapter instMv=new InstructionAdapter(oriMv){

                @Override
                public void visitInsn(int opcode) {
                    System.out.println(opcode);
                    super.visitInsn(opcode);
                }
                
            };
            return instMv;
            
        }
               

    }
    
    
    public static void main(String[] args) throws Exception{
        InputStream in=ASMHelloWorld.class.getResourceAsStream("/com/geekyarticles/asm/ASMHelloWorld.class");
        ClassReader classReader=new ClassReader(in);
        classReader.accept(new MethodPrinterVisitor(4), 0);

    }

}

The following is the output in this case.

<init>()V
177

main([Ljava/lang/String;)V
89
89
3
177

Note that the instructions are direct opcodes.

Generating Class: Before discussing the details of generating a class, I will talk about a real cool thing that is available in ASM. Its called ASMifier. Its a class that prints the code requred to generate a given class. The following example shows how to use ASMifier. The class has got a main method and hence can be used from the command prompt.

java -cp asm-all-4.0_RC2.jar org.objectweb.asm.util.ASMifier java.lang.String>>StringDump.java

And the following is the output.

StringDump.java

package asm.java.lang;
import java.util.*;
import org.objectweb.asm.*;
import org.objectweb.asm.attrs.*;
public class StringDump implements Opcodes {

public static byte[] dump () throws Exception {

ClassWriter cw = new ClassWriter(0);

cw.visit(V1_5, ACC_PUBLIC + ACC_FINAL + ACC_SUPER, "java/lang/String", "Ljava/lang/Object;Ljava/io/Serializable;Ljava/lang/Comparable<Ljava/lang/String;>;Ljava/lang/CharSequence;", "java/lang/Object", new String[] { "java/io/Serializable", "java/lang/Comparable", "java/lang/CharSequence" });

cw.visitInnerClass("java/lang/String$1", "java/lang/String", null, ACC_STATIC + ACC_SYNTHETIC);

cw.visitInnerClass("java/lang/String$CaseInsensitiveComparator", "java/lang/String", "CaseInsensitiveComparator", ACC_PRIVATE + ACC_STATIC);

{
fv = cw.visitField(ACC_PRIVATE + ACC_FINAL, "value", "[C", null, null);
fv.visitEnd();
}
{

}
{

fv.visitEnd();
}
{

fv.visitEnd();
}
{
fv = cw.visitField(ACC_PUBLIC + ACC_FINAL + ACC_STATIC, "CASE_INSENSITIVE_ORDER", "Ljava/util/Comparator;", "Ljava/util/Comparator<Ljava/lang/String;>;", null);
fv.visitEnd();

The code shows how to create most of the class artifacts. I would now explain parts of the code. However, I will use a simpler class for demonstration and also like to add appropriate comments. The reason why I discussed the above is that in case you get stuck about how to create a particular artifact, you can simply compile a class having it and then generate code using ASMifier to see how it is created. I will use the following code as an example. The class ClassCreationDemoMaker creates a class that would have been the result of compiling the class ClassCreationDemo.

ClassCreationDemo.java

package com.geekyarticles.asm;

public class ClassCreationDemo {
    private int version;
    
    public int getVersion() {

    }

    public void setVersion(int version) {
        this.version = version;
    }

    @Override
    public String toString(){
        return "ClassCreationDemo: "+version;
    }
}

The fundamental principle of creating a class is to use an object of ClassWriter, which is a ClassVisitor, and then call different visit methods in it in proper order. In this case we have only created one field and three methods. It is mandatory to create the constructor. The code is very simple to understand. Note that after calling the visitMethod method in the ClassWriter, we have used the MethodWriter returned from it to write the code in the method. Here also note that we have manually allocated the maximum stack size for each method. We can alternatively use ClassWriter.COMPUTE_MAXS flag in the ClassWriter constructor to avoid doing this.

Writing a class is always an in-memory process. This is because the constants used in the class always needs to be in the constant pool, which is near the start of the class and it stores all the field and method names and every other things.

Modifying classes: Honestly, this is where ASM shines, because of its sheer ease of use. In this section, we are going to create the class ClassModifierDemo which modifies the class ClassModificationDemo. The job of the modifier is to insert a code in each method invocation (including constructors) that prints its name.

ClassModifierDemo.java

package com.geekyarticles.asm;

import java.io.DataOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;

import org.objectweb.asm.ClassReader;
import org.objectweb.asm.ClassVisitor;
import org.objectweb.asm.ClassWriter;
import org.objectweb.asm.MethodVisitor;
import org.objectweb.asm.Opcodes;

public class ClassModifierDemo {

    public static class ModifierMethodWriter extends MethodVisitor{

        private String methodName;
        
        public ModifierMethodWriter(int api, MethodVisitor mv, String methodName) {
            super(api, mv);
            this.methodName=methodName;
        }

        //This is the point we insert the code. Note that the instructions are added right after
        //the visitCode method of the super class. This ordering is very important.
        @Override
        public void visitCode() {
            super.visitCode();
            super.visitFieldInsn(Opcodes.GETSTATIC, "java/lang/System", "out", "Ljava/io/PrintStream;");
            super.visitLdcInsn("method: "+methodName);
            super.visitMethodInsn(Opcodes.INVOKEVIRTUAL, "java/io/PrintStream", "println", "(Ljava/lang/String;)V");
        }

        
        
    }
    
    //Our class modifier class visitor. It delegate all calls to the super class
    //Only makes sure that it returns our MethodVisitor for every method
    public static class ModifierClassWriter extends ClassVisitor{
        private int api;
        public ModifierClassWriter(int api, ClassWriter cv) {
            super(api, cv);
            this.api=api;
        }

        @Override
        public MethodVisitor visitMethod(int access, String name, String desc,
                String signature, String[] exceptions) {

            MethodVisitor mv= super.visitMethod(access, name, desc, signature, exceptions);
            ModifierMethodWriter mvw=new ModifierMethodWriter(api, mv, name);
            return mvw;
        }
        
        
        
    }

    public static void main(String[] args) throws IOException {
        InputStream in=ASMHelloWorld.class.getResourceAsStream("/com/geekyarticles/asm/ClassModificationDemo.class");
        ClassReader classReader=new ClassReader(in);
        ClassWriter cw=new ClassWriter(ClassWriter.COMPUTE_MAXS);
        
        //Wrap the ClassWriter with our custom ClassVisitor
        ModifierClassWriter mcw=new ModifierClassWriter(Opcodes.ASM4, cw);
        classReader.accept(mcw, 0);
        
        //Write the output to a class file
        File outputDir=new File("out/com/geekyarticles/asm");
        outputDir.mkdirs();
        DataOutputStream dout=new DataOutputStream(new FileOutputStream(new File(outputDir,"ClassModificationDemo.class")));
        dout.write(cw.toByteArray());
    }

}

ClassModificationDemo.java

package com.geekyarticles.asm;

public class ClassModificationDemo {

private int version;
    
    public int getVersion() {
        return version;
    }

    public void setVersion(int version) {
        this.version = version;
    }

    @Override
    public String toString(){
        return "ClassCreationDemo: "+version;
    }
    
    public static void main(String[] args) {
        System.out.println(new ClassModificationDemo());

    }

}

This example is a combination of reading and creating a class. In this case we simply wrap the ClassWriter with our own ClassVisitor. It simply delegates all calls directly to the ClassWriter except the visitMethod, which in turn is written to wrap the MethodVisitor returned by the ClassWriter with our own. MethodVisitor also directly delegates all calls to the super class except visitCode, which it uses to insert the custom code.

After running the program, a new version of ClassModificationDemo will be created in the out directory with proper package structure. Now we can run the ClassModificationDemo class from out directory and see the result. It will print which method is invoked when.
