Constructor Detail

DOMCipherReference

public DOMCipherReference(java.lang.String uri,
                          java.util.List tfs)

Creates a CiphereReference from the specified parameters.

Parameters:

uri - the URI

tfs - a list of Transforms. The list is defensively copied to protect against subsequent modification. May be null or empty.

Throws:

java.lang.NullPointerException - if dm is null

java.lang.ClassCastException - if any of the transforms are not of type Transform

DOMCipherReference

public DOMCipherReference(org.w3c.dom.Element parent,
                          org.w3c.dom.Element elem,
                          XMLCryptoContext context)
                   throws MarshalException

Creates a DOMCipherReference from an element.

Parameters:

elem - a CipherReference element

Throws:

MarshalException

Method Detail

getType

public java.lang.String getType()

Description copied from interface: URIReference

Returns the type of data referenced by this URI.

Specified by:

getType in interface URIReference

Returns:

the type (a URI) of the data object (may be null if not specified)

getURI

public java.lang.String getURI()

Description copied from interface: URIReference

Returns the URI of the referenced data object.

Specified by:

getURI in interface URIReference

Returns:

the URI of the data object in RFC 2396 format (may be null if not specified)

getTransforms

public java.util.List getTransforms()

Description copied from interface: CipherReference

Returns an unmodifiable list of Transforms that describe how to transform the referenced cipher data into an octet sequence.

Specified by:

getTransforms in interface CipherReference

Returns:

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

getCipherValue

public java.io.InputStream getCipherValue()
                                   throws XMLEncryptionException

Throws:

XMLEncryptionException

getCipherValue

public java.io.InputStream getCipherValue(XMLCryptoContext ctx)
                                   throws XMLEncryptionException

Throws:

XMLEncryptionException

marshal

public void marshal(org.w3c.dom.Node parent,
                    java.lang.String encPrefix,
                    DOMCryptoContext context)
             throws MarshalException

Specified by:

marshal in class DOMStructure

Throws:

MarshalException

getHere

public org.w3c.dom.Node getHere()

Description copied from interface: DOMURIReference

Returns the here node.

Specified by:

getHere in interface DOMURIReference

Returns:

the attribute or processing instruction node or the parent element of the text node that directly contains the URI

equals
