Examples of org.objectweb.asm.ClassVisitor.visit()

org.objectweb.asm.ClassVisitor.visit()
Visits the header of the class. @param version the class version. @param access the class's access flags (see {@link Constants}). This parameter also indicates if the class is deprecated. @param name the internal name of the class (see {@link Type#getInternalName() getInternalName}). @param superName the internal of name of the super class (see {@link Type#getInternalName() getInternalName}). For interfaces, the super class is {@link Object}. May be null, but only for the {@link Object java.lang.Object} class. @param interfaces the internal names of the class's interfaces (see {@link Type#getInternalName() getInternalName}). May be null. @param sourceFile the name of the source file from which this class wascompiled. May be null.
