List < Integer > function ( ) { return this . operationMonitor ; }
gets the value of the operationmonitor 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 operationmonitor property . for example , to add a new item , do as follows : getoperationmonitor . add newitem ; objects of the following type s are allowed in the list integer concode_field_sep String expireBefore concode_elem_sep String expireAfter concode_elem_sep String createdAfter concode_elem_sep Integer sizeBelow concode_elem_sep String unmodifiedSince concode_elem_sep List<Integer> operationMonitor concode_elem_sep String NL concode_elem_sep Integer sizeAbove concode_elem_sep List<Integer> notificationEventType concode_elem_sep String modifiedSince concode_elem_sep Integer stateTagSmaller concode_elem_sep Integer stateTagBigger concode_elem_sep String createdBefore concode_elem_sep List<Attribute> attribute concode_field_sep void setStateTagBigger concode_elem_sep String getCreatedBefore concode_elem_sep Integer getSizeBelow concode_elem_sep void setSizeBelow concode_elem_sep List<Attribute> getAttribute concode_elem_sep Integer getStateTagSmaller concode_elem_sep List<Integer> getNotificationEventType concode_elem_sep void setUnmodifiedSince concode_elem_sep void addNotificationEventType concode_elem_sep String getUnmodifiedSince concode_elem_sep void addOperationMonitor concode_elem_sep String getExpireBefore concode_elem_sep void setStateTagSmaller concode_elem_sep String getCreatedAfter concode_elem_sep void setCreatedAfter concode_elem_sep void setExpireAfter concode_elem_sep String getExpireAfter concode_elem_sep Integer getStateTagBigger concode_elem_sep void setExpireBefore concode_elem_sep void setSizeAbove concode_elem_sep void addAttribute concode_elem_sep void setCreatedBefore concode_elem_sep void setModifiedSince concode_elem_sep String getModifiedSince concode_elem_sep String toString concode_elem_sep Integer getSizeAbove
