Class OSGiFriendlyClassWriter

java.lang.Object
  org.objectweb.asm.ClassWriter
      org.apache.aries.proxy.impl.common.OSGiFriendlyClassWriter

All Implemented Interfaces:

org.objectweb.asm.ClassVisitor

public final class OSGiFriendlyClassWriter
extends org.objectweb.asm.ClassWriter

We need to override ASM's default behaviour in getCommonSuperClass(String, String) so that it doesn't load classes (which it was doing on the wrong ClassLoader anyway...)

Field Summary

Constructor Summary

OSGiFriendlyClassWriter(org.objectweb.asm.ClassReader arg0, int arg1, ClassLoader loader)

OSGiFriendlyClassWriter(int arg0, ClassLoader loader)

Method Summary

protected String	getCommonSuperClass(String arg0, String arg1) We provide an implementation that doesn't cause class loads to occur.
void	visit(int arg0, int arg1, String arg2, String arg3, String arg4, String[] arg5) We need access to the super's name and our class name
org.objectweb.asm.MethodVisitor	visitMethod(int arg0, String arg1, String arg2, String arg3, String[] arg4)

Constructor Detail

OSGiFriendlyClassWriter

public OSGiFriendlyClassWriter(org.objectweb.asm.ClassReader arg0,
                               int arg1,
                               ClassLoader loader)

OSGiFriendlyClassWriter

public OSGiFriendlyClassWriter(int arg0,
                               ClassLoader loader)

Method Detail

getCommonSuperClass

protected final String getCommonSuperClass(String arg0,
                                           String arg1)

We provide an implementation that doesn't cause class loads to occur. It may not be sufficient because it expects to find the common parent using a single classloader, though in fact the common parent may only be loadable by another bundle from which an intermediate class is loaded

Overrides:

getCommonSuperClass in class org.objectweb.asm.ClassWriter

visit

public final void visit(int arg0,
                        int arg1,
                        String arg2,
                        String arg3,
                        String arg4,
                        String[] arg5)

We need access to the super's name and our class name

Specified by:

visit in interface org.objectweb.asm.ClassVisitor

Overrides:

visit in class org.objectweb.asm.ClassWriter

visitMethod

public org.objectweb.asm.MethodVisitor visitMethod(int arg0,
                                                   String arg1,
                                                   String arg2,
                                                   String arg3,
                                                   String[] arg4)

Specified by:

visitMethod in interface org.objectweb.asm.ClassVisitor

Overrides:

visitMethod in class org.objectweb.asm.ClassWriter
