question: gets the value of the any property . this accessor method returns a reference to the live list , not a snapshot . therefore any modification you make to the returned list will be present inside the jaxb object . this is why there is not a set method for the any property . for example , to add a new item , do as follows : getany . add newitem ; objects of the following type s are allowed in the list object element concode_field_sep WadlGrammars grammars concode_elem_sep List<WadlDoc> doc concode_elem_sep List<WadlResources> resources concode_elem_sep List<Object> any concode_elem_sep List<Object> resourceTypeOrMethodOrRepresentation concode_field_sep WadlGrammars getGrammars concode_elem_sep List<Object> getResourceTypeOrMethodOrRepresentation concode_elem_sep void setGrammars concode_elem_sep List<WadlResources> getResources concode_elem_sep List<WadlDoc> getDoc
target: List < Object > function ( ) { if ( any == null ) { any = new ArrayList < Object > ( ) ; } return this . any ; }
