gets the value of the signatureinformationextension 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 signatureinformationextension property . for example , to add a new item , do as follows : getsignatureinformationextension . add newitem ; objects of the following type s are allowed in the list extensioncomplextype concode_field_sep List<MdSecDefinition> mdSec concode_elem_sep SignatureComplexType signature concode_elem_sep List<ExtensionComplexType> signatureInformationExtension concode_elem_sep List<Object> signatureInformationExtensionOrMdSec concode_field_sep List<Object> getSignatureInformationExtensionOrMdSec concode_elem_sep void setSignature concode_elem_sep List<MdSecDefinition> getMdSec concode_elem_sep SignatureComplexType getSignature
List < ExtensionComplexType > function ( ) { if ( signatureInformationExtension == null ) { signatureInformationExtension = new ArrayList < ExtensionComplexType > ( ) ; } return this . signatureInformationExtension ; }
