Interface URIDereferencer

public interface URIDereferencer

A dereferencer of URIReferences.

Unless the URIReference is a same-document reference as defined in section 4.2 of the W3C Recommendation for XML-Signature Syntax and Processing, the result of dereferencing the URIReference MUST be an OctetStreamData.
