URIDereferencer (Java Platform SE 8 ) (original) (raw)

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

     [Data](../../../javax/xml/crypto/Data.html "interface in javax.xml.crypto") dereference([URIReference](../../../javax/xml/crypto/URIReference.html "interface in javax.xml.crypto") uriReference,  
                      [XMLCryptoContext](../../../javax/xml/crypto/XMLCryptoContext.html "interface in javax.xml.crypto") context)  
               throws [URIReferenceException](../../../javax/xml/crypto/URIReferenceException.html "class in javax.xml.crypto")  
     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](../../../java/lang/NullPointerException.html "class in java.lang")` \- if `uriReference` or`context` are `null`  
     `[URIReferenceException](../../../javax/xml/crypto/URIReferenceException.html "class in javax.xml.crypto")` \- if an exception occurs while dereferencing the specified `uriReference`
