question: gets the value of the trdgsesrulesgrp 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 trdgsesrulesgrp property . for example , to add a new item , do as follows : gettrdgsesrulesgrp . add newitem ; objects of the following type s are allowed in the list tradingsessionrulesgrpblockt concode_field_sep BaseTradingRulesBlockT baseTrdgRules concode_elem_sep List<TradingSessionRulesGrpBlockT> trdgSesRulesGrp concode_elem_sep List<NestedInstrumentAttributeBlockT> attrb concode_field_sep List<NestedInstrumentAttributeBlockT> getAttrb concode_elem_sep void setBaseTrdgRules concode_elem_sep BaseTradingRulesBlockT getBaseTrdgRules
target: List < TradingSessionRulesGrpBlockT > function ( ) { if ( trdgSesRulesGrp == null ) { trdgSesRulesGrp = new ArrayList < TradingSessionRulesGrpBlockT > ( ) ; } return this . trdgSesRulesGrp ; }
