gets the value of the sqref 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 sqref property . for example , to add a new item , do as follows : getsqref . add newitem ; objects of the following type s are allowed in the list string concode_field_sep String formula1 concode_elem_sep Boolean allowBlank concode_elem_sep Object parent concode_elem_sep Boolean showErrorMessage concode_elem_sep String formula2 concode_elem_sep STDataValidationImeMode imeMode concode_elem_sep Boolean showDropDown concode_elem_sep Boolean showInputMessage concode_elem_sep STDataValidationType type concode_elem_sep String error concode_elem_sep STDataValidationOperator operator concode_elem_sep STDataValidationErrorStyle errorStyle concode_elem_sep String errorTitle concode_elem_sep String promptTitle concode_elem_sep List<String> sqref concode_elem_sep String prompt concode_field_sep boolean isAllowBlank concode_elem_sep String getErrorTitle concode_elem_sep void setAllowBlank concode_elem_sep void setPrompt concode_elem_sep void afterUnmarshal concode_elem_sep void setErrorStyle concode_elem_sep void setFormula1 concode_elem_sep void setFormula2 concode_elem_sep void setPromptTitle concode_elem_sep void setOperator concode_elem_sep void setParent concode_elem_sep STDataValidationOperator getOperator concode_elem_sep boolean isShowDropDown concode_elem_sep STDataValidationErrorStyle getErrorStyle concode_elem_sep STDataValidationImeMode getImeMode concode_elem_sep boolean isShowInputMessage concode_elem_sep Object getParent concode_elem_sep void setImeMode concode_elem_sep String getFormula1 concode_elem_sep String getFormula2 concode_elem_sep void setShowErrorMessage concode_elem_sep String getPrompt concode_elem_sep void setType concode_elem_sep void setShowInputMessage concode_elem_sep boolean isShowErrorMessage concode_elem_sep String getError concode_elem_sep void setShowDropDown concode_elem_sep STDataValidationType getType concode_elem_sep void setError concode_elem_sep void setErrorTitle concode_elem_sep String getPromptTitle
