Code generation for Jackson stream parsing with live template

I would like to use live template to generate stream parsing code.

Below is what I want to achieve, assume there is a json,

{

     "type":1,

     "content":"abc"

     .....

}

In Intellij, I would like to generate code to parse above Json. I type

{"type","content", ....}

then .<template> name and press Tab. Intellij generates code as below

//----Start generated code-----

      while(parser.nextToken() != JsonToken.END_OBJECT){

            String fieldName = parser.getCurrentName();

            // Let's move to value

            parser.nextToken();

            if("type".equals(fieldName)){

                //Tab selection

            }else if("content".equals(fieldName)){

                //Tab selection

            }

            ............

            else{

                parser.skipChildren();

            }

        }

//----End generated code-----

I found that such as  $ARRAY$[$INDEX$], but there is no way to evaluate the value of the variable.

Do anyone have an idea to write such live template? Thanks!
