Interface URIDereferencer

```
public interface URIDereferencer
```
A dereferencer of URIReferences.
The result of dereferencing a URIReference is either an instance of OctetStreamData or NodeSetData. 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.

Since:

1.6

```
Data dereference(URIReference uriReference,
                 XMLCryptoContext context)
          throws URIReferenceException
```
    Dereferences the specified URIReference and returns the dereferenced data.
    
    Parameters:
    
    uriReference - the URIReference
    
    context - an XMLCryptoContext that may contain additional useful information for dereferencing the URI. This implementation should dereference the specified URIReference against the context's baseURI parameter, if specified.
    
    Returns:
    
    the dereferenced data
    
    Throws:
    
    NullPointerException - if uriReference or context are null
    
    URIReferenceException - if an exception occurs while dereferencing the specified uriReference
