Examples of jodd.asm5.MethodVisitor.visitMethodInsn()

jodd.asm5.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. This opcode 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.visitFieldInsn(GETFIELD, implClassName, cmrField.getName(), cmrField.getDescriptor());


        // return this.${cmrField.name}Cmr.get(this.${cmdField.name});  
        // this takes the value stored in the CMR field (which might be a single value or 
        // a Set or Collection), and hands it to the appropriate accessor. 
        mv.visitMethodInsn(INVOKEVIRTUAL, cmrField.getAccessorInternalName(), "get", cmrField.getCmrStyle().getGetterDescriptor(), false);
        // if the style is a single value, then we're going to need to cast this 
        // to the target class before returning.  
        if (cmrField.getCmrStyle() == CmrStyle.SINGLE) {
