Examples of org.objectweb.asm.MethodVisitor.visitMethodInsn()

org.objectweb.asm.MethodVisitor.visitMethodInsn()
Visits a method instruction. A method instruction is an instruction that invokes a method. @param opcode the opcode of the type instruction to be visited. Thisopcode is either INVOKEVIRTUAL, INVOKESPECIAL, INVOKESTATIC or INVOKEINTERFACE. @param owner the internal name of the method's owner class (see {@link Type#getInternalName() getInternalName}). @param name the method's name. @param desc the method's descriptor (see {@link Type Type}).

        mv.visitLocalVariable("this", "L" + classFileName + ";", null, lbegin, lend, 0);
