question: like jsongenerator #writeobjectfield string , object but supports maps and lists . concode_field_sep PlaceHolder placeHolder concode_field_sep void writeList concode_elem_sep void writeMap
target: void function ( JsonGenerator arg0 , String arg1 , Object arg2 ) { if ( arg2 instanceof Map ) { writeMap ( arg0 , arg1 , ( Map ) arg2 ) ; } else if ( arg2 instanceof List ) { writeList ( arg0 , arg1 , ( List ) arg2 ) ; } else { arg0 . writeObjectField ( arg1 , arg2 ) ; } }
