Constructor Detail

DigestValueImpl

public DigestValueImpl()

Creates a new instance of this DigestValueImpl.

DigestValueImpl

public DigestValueImpl(byte[] value)

Creates a new instance of this DigestValueImpl with the digest value.

Parameters:

value - the raw digest value

DigestValueImpl

public DigestValueImpl(DOMCryptoContext context,
                       Node node)
                throws MarshalException

Creates a new instance of this DigestValueImpl with the specified context and node to unmarshal from.

Parameters:

context - the context

node - the node to unmarshal from

Throws:

MarshalException - if an exception occurs during unmarshaling

Method Detail

getDigestValue

public byte[] getDigestValue()

Returns the digest value.

Returns:

the raw digest value. Each invocation of this method returns a new clone to protect against subsequent modification.

getLocalName

public String getLocalName()

Description copied from class: DOMStructure

Returns the local name of the represented XML element.

Specified by:

getLocalName in class DOMStructure

Returns:

the local name of the represented XML element

See Also:

DOMStructure.getLocalName()

marshalElement

protected Element marshalElement(DOMCryptoContext context,
                                 Node parent,
                                 Node nextSibling)
                          throws MarshalException

Marshals the digest value if not marshaled yet.

Overrides:

marshalElement in class DOMStructure

Parameters:

context - the marshal context

parent - where to place the marshalled element

nextSibling - before which to place the marshalled node

Returns:

the marshaled Element

Throws:

MarshalException - if an exception occurs during marshaling

appendValue

public void appendValue(DOMCryptoContext context,
                        byte[] value)
                 throws MarshalException

Appends the given digest value.

Parameters:

context - the context

value - the raw digest value

Throws:

MarshalException - if an exception occurs during marshaling

unmarshalElement

protected void unmarshalElement(DOMCryptoContext context,
                                Element element)
                         throws MarshalException

Unmarshals the digest value.

Overrides:

unmarshalElement in class DOMStructure

Parameters:

context - the marshal context

element - the element to be unmarshal

Throws:

MarshalException - if an exception occurs during unmarshaling
