Class DOMSignContext

java.lang.Object

javax.xml.crypto.dom.DOMCryptoContext

javax.xml.crypto.dsig.dom.DOMSignContext

All Implemented Interfaces:

XMLSignContext, XMLCryptoContext

public class DOMSignContext
extends DOMCryptoContext
implements XMLSignContext

A DOM-specific XMLSignContext. This class contains additional methods to specify the location in a DOM tree where an XMLSignature object is to be marshalled when generating the signature.

Note that DOMSignContext instances can contain information and state specific to the XML signature structure it is used with. The results are unpredictable if a DOMSignContext is used with different signature structures (for example, you should not use the same DOMSignContext instance to sign two different XMLSignature objects).

Implementation Note:

The JDK implementation supports the following properties that can be set using the setProperty method.

• org.jcp.xml.dsig.internal.dom.SignatureProvider: value must be a Provider. If specified, the underlying Signature will be instantiated from this provider.
• jdk.xmldsig.SecureRandom: value must be a SecureRandom. If specified, this object will be used to initialize the underlying Signature during signing using the Signature.initSign(PrivateKey, SecureRandom) method.

1.6

Constructor Details

DOMSignContext

public DOMSignContext(Key signingKey,
 Node parent)

Creates a DOMSignContext with the specified signing key and parent node. The signing key is stored in a singleton KeySelector that is returned by the getKeySelector method. The marshalled XMLSignature will be added as the last child element of the specified parent node unless a next sibling node is specified by invoking the setNextSibling method.

Parameters:

signingKey - the signing key

parent - the parent node

Throws:

NullPointerException - if signingKey or parent is null

DOMSignContext

public DOMSignContext(Key signingKey,
 Node parent,
 Node nextSibling)

Creates a DOMSignContext with the specified signing key, parent and next sibling nodes. The signing key is stored in a singleton KeySelector that is returned by the getKeySelector method. The marshalled XMLSignature will be inserted as a child element of the specified parent node and immediately before the specified next sibling node.

Parameters:

signingKey - the signing key

parent - the parent node

nextSibling - the next sibling node

Throws:

NullPointerException - if signingKey, parent or nextSibling is null

DOMSignContext

public DOMSignContext(KeySelector ks,
 Node parent)

Creates a DOMSignContext with the specified key selector and parent node. The marshalled XMLSignature will be added as the last child element of the specified parent node unless a next sibling node is specified by invoking the setNextSibling method.

Parameters:

ks - the key selector

parent - the parent node

Throws:

NullPointerException - if ks or parent is null

DOMSignContext

public DOMSignContext(KeySelector ks,
 Node parent,
 Node nextSibling)

Creates a DOMSignContext with the specified key selector, parent and next sibling nodes. The marshalled XMLSignature will be inserted as a child element of the specified parent node and immediately before the specified next sibling node.

Parameters:

ks - the key selector

parent - the parent node

nextSibling - the next sibling node

Throws:

NullPointerException - if ks, parent or nextSibling is null

Method Details

setParent

public void setParent(Node parent)

Sets the parent node.

Parameters:

NullPointerException - if parent is null

See Also:

• getParent()

setNextSibling

public void setNextSibling(Node nextSibling)

Sets the next sibling node.

Parameters:

nextSibling - the next sibling node. The marshalled XMLSignature will be inserted immediately before this node. Specify null to remove the current setting.

See Also:

• getNextSibling()

getParent

public Node getParent()

Returns the parent node.

Returns:

the parent node (never null)

See Also:

• setParent(Node)

getNextSibling

public Node getNextSibling()

Returns the nextSibling node.
