Interface XMLObject

All Superinterfaces:

XMLStructure

public interface XMLObject
extends XMLStructure

A representation of the XML Object element as defined in the W3C Recommendation for XML-Signature Syntax and Processing. An XMLObject may contain any data and may include optional MIME type, ID, and encoding attributes. The XML Schema Definition is defined as:

 <element name="Object" type="ds:ObjectType"/>
 <complexType name="ObjectType" mixed="true">
   <sequence minOccurs="0" maxOccurs="unbounded">
     <any namespace="##any" processContents="lax"/>
   </sequence>
   <attribute name="Id" type="ID" use="optional"/>
   <attribute name="MimeType" type="string" use="optional"/>
   <attribute name="Encoding" type="anyURI" use="optional"/>
 </complexType>
 

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

   XMLSignatureFactory fac = XMLSignatureFactory.getInstance("DOM");
   List content = Collections.singletonList(fac.newManifest(references)));
   XMLObject object = factory.newXMLObject(content, "object-1", null, null);
 

Note that this class is named XMLObject rather than Object to avoid naming clashes with the existing java.lang.Object class.

Since:

1.6

Method Detail

getContent

List getContent()

Returns an unmodifiable list of XMLStructures contained in this XMLObject, which represent elements from any namespace.

If there is a public subclass representing the type of XMLStructure, it is returned as an instance of that class (ex: a SignatureProperties element would be returned as an instance of SignatureProperties).

Returns:

an unmodifiable list of XMLStructures (may be empty but never null)

getId

String getId()

Returns the Id of this XMLObject.

Returns:

the Id (or null if not specified)

getMimeType

String getMimeType()

Returns the mime type of this XMLObject. The mime type is an optional attribute which describes the data within this XMLObject (independent of its encoding).

Returns:

the mime type (or null if not specified)

getEncoding

String getEncoding()

Returns the encoding URI of this XMLObject. The encoding URI identifies the method by which the object is encoded.

Returns:

the encoding URI (or null if not specified)
