Constructor Detail

DigestAlgAndValueType

protected DigestAlgAndValueType(Node node)
                         throws MarshalException

Creates a new instance of this DigestAlgAndValueType with the specified provider config and node.

Parameters:

node - the node to unmarshal from

Throws:

MarshalException - if an exception occurs during unmarshaling

DigestAlgAndValueType

protected DigestAlgAndValueType(DigestMethodImpl digestMethod)

Creates a new instance of this DigestAlgAndValueType with the specified provider config and digest method.

Parameters:

digestMethod - the digest method

Throws:

NullPointerException - if config or digestMethod is null

DigestAlgAndValueType

protected DigestAlgAndValueType(DigestMethodImpl digestMethod,
                                byte[] digestValue)

Creates a new instance of this DigestAlgAndValueType with the specified provider config, digest method and digest value.

Parameters:

digestMethod - the digest method

digestValue - the digest value

Throws:

NullPointerException - if config, digestMethod or digestValue is null

Method Detail

getDigestMethod

public DigestMethod getDigestMethod()

Returns the digest method.

Returns:

the digest method.

getDigestValue

public byte[] getDigestValue()

Returns the raw digest value.

Returns:

the raw digest value, or null if the digest value has not been computed set or has not been computed yet.

getChildStructures

protected List getChildStructures()

Description copied from class: DOMStructure

Returns the list of child structures of this DOMStructure.

This method is called by DOMStructure.marshal(DOMCryptoContext, Node, Node).

A subclass has to overwrite this method to return a list of DOMStrucutres represented by this subclass.

Overrides:

getChildStructures in class DOMStructure

Returns:

a list of DOMStructures (may be empty, but never null)

See Also:

DOMStructure.getChildStructures()

putChildStructure

protected void putChildStructure(DOMStructure childStructure)
                          throws MarshalException

Description copied from class: DOMStructure

Put an unmarshalled child structure.

This method is called by DOMStructure.unmarshalStructures(NodeList, DOMCryptoContext) for every unmarshalled child structure.

A subclass has to overwrite this method to store the given child structure in its the corresponding field.

Overrides:

putChildStructure in class DOMStructure

Parameters:

childStructure - the unmarshalled child structure

Throws:

MarshalException

See Also:

DOMStructure.putChildStructure(iaik.xml.crypto.dom.DOMStructure)

calculateDigestValue

public byte[] calculateDigestValue(InputStream digestInput,
                                   XMLCryptoContext context)
                            throws XMLSignatureException,
                                   IOException

Calculates the digest value of the given digest input.

Parameters:

digestInput - the input for the digest computation

context - the context

Returns:

the calculated raw digest value

Throws:

XMLSignatureException

IOException

calculateAndAppendDigestValue

public void calculateAndAppendDigestValue(DOMCryptoContext context,
                                          InputStream digestInput)
                                   throws MarshalException,
                                          XMLSignatureException,
                                          IOException

Calculated the digest value from the given digest input and marshals the digest value.

Parameters:

context - the context

digestInput - the input for the digest computation

Throws:

MarshalException

XMLSignatureException

IOException

toString

public String toString()

Overrides:

toString in class DOMStructure
