Interface Transform

All Superinterfaces:

AlgorithmMethod, XMLStructure

All Known Subinterfaces:

CanonicalizationMethod

public interface Transform

extends XMLStructure, AlgorithmMethod

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

 <element name="Transform" type="ds:TransformType"/>
   <complexType name="TransformType" mixed="true">
     <choice minOccurs="0" maxOccurs="unbounded">
       <any namespace="##other" processContents="lax"/>
       <!-- (1,1) elements from (0,unbounded) namespaces -->
       <element name="XPath" type="string"/>
     </choice>
     <attribute name="Algorithm" type="anyURI" use="required"/>
   </complexType>
 

A Transform instance may be created by invoking the newTransform method of the XMLSignatureFactory class.

XMLSignatureFactory.newTransform(String, TransformParameterSpec)

Method Detail

getParameterSpec

public AlgorithmParameterSpec getParameterSpec()

Returns the algorithm-specific input parameters associated with this Transform.

The returned parameters can be typecast to a TransformParameterSpec object.

Specified by:

getParameterSpec in interface AlgorithmMethod

Returns:

the algorithm-specific input parameters (may be null if not specified)
