Interface SignatureProperty

All Superinterfaces:: XMLStructure

public interface SignatureProperty
extends XMLStructure
extends XMLStructure

A representation of the XML SignatureProperty element as defined in the W3C Recommendation for XML-Signature Syntax and Processing. The XML Schema Definition is defined as:


<element name="SignatureProperty" type="ds:SignaturePropertyType"/> 
   <complexType name="SignaturePropertyType" mixed="true">
     <choice maxOccurs="unbounded"> 
       <any namespace="##other" processContents="lax"/>
       <!-- (1,1) elements from (1, unbounded) namespaces -->
     </choice>
     <attribute name="Target" type="anyURI" use="required"/> 
     <attribute name="Id" type="ID" use="optional"/> 
   </complexType>

A SignatureProperty instance may be created by invoking the newSignatureProperty method of the XMLSignatureFactory class; for example:

   XMLSignatureFactory factory = XMLSignatureFactory.getInstance("DOM");
   SignatureProperty property = factory.newSignatureProperty
        (Collections.singletonList(content), "#Signature-1", "TimeStamp");

Since:: 1.6
See Also:: XMLSignatureFactory.newSignatureProperty(List, String, String), SignatureProperties
