All Implemented Interfaces:

DOMIdMap, XMLCryptoContext, XMLValidateContext

public class DOMValidateContext

extends Object

implements XMLValidateContext, DOMIdMap

A DOM-specific XMLValidateContext. This class contains additional methods to specify the location in a DOM tree where an XMLSignature is to be unmarshalled and validated from.

Note that the behavior of an unmarshalled XMLSignature is undefined if the contents of the underlying DOM tree are modified by the caller after the XMLSignature is created.

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

Constructor Detail

DOMValidateContext

public DOMValidateContext(KeySelector ks,
                          Node node)

Creates a DOMValidateContext containing the specified key selector and node.

Parameters:

ks - a key selector for finding a validation key

node - the node

Throws:

NullPointerException - if ks or node is null

DOMValidateContext

public DOMValidateContext(Key validatingKey,
                          Node node)

Creates a DOMValidateContext containing the specified key and node. The validating key is stored in a singleton KeySelector that is returned by the getKeySelector method.

Parameters:

validatingKey - the validating key

node - the node

Throws:

NullPointerException - if validatingKey or node is null

DOMValidateContext

public DOMValidateContext(Node node)

Creates a DOMValidateContext containing the specified node. This constructor is useful if you only want to unmarshal (and not validate) an XMLSignature.

Parameters:

node - the node

Throws:

NullPointerException - if node is null

Method Detail

setNode

public void setNode(Node node)

Sets the node.

Parameters:

node - the node

Throws:

NullPointerException - if node is null

See Also:

getNode()

getNode

public Node getNode()

Returns the node.

Returns:

the node (never null)

See Also:

setNode(Node)

getKeySelector

public KeySelector getKeySelector()

Description copied from interface: XMLCryptoContext

Returns the key selector for finding a key.

Specified by:

getKeySelector in interface XMLCryptoContext

Returns:

the key selector, or null if not specified

See Also:

XMLCryptoContext.setKeySelector(KeySelector)

setKeySelector

public void setKeySelector(KeySelector ks)

Description copied from interface: XMLCryptoContext

Sets the key selector for finding a key.

Specified by:

setKeySelector in interface XMLCryptoContext

Parameters:

ks - the key selector, or null to remove the current setting

See Also:

XMLCryptoContext.getKeySelector()

getBaseURI

public String getBaseURI()

Description copied from interface: XMLCryptoContext

Returns the base URI.

Specified by:

getBaseURI in interface XMLCryptoContext

Returns:

the base URI, or null if not specified

See Also:

XMLCryptoContext.setBaseURI(String)

setBaseURI

public void setBaseURI(String baseURI)

Description copied from interface: XMLCryptoContext

Sets the base URI.

Specified by:

setBaseURI in interface XMLCryptoContext

Parameters:

baseURI - the base URI, or null to remove current value

Throws:

IllegalArgumentException

See Also:

XMLCryptoContext.getBaseURI()

getURIDereferencer

public URIDereferencer getURIDereferencer()

Description copied from interface: XMLCryptoContext

Returns a URIDereferencer that is used to dereference URIReferences.

Specified by:

getURIDereferencer in interface XMLCryptoContext

Returns:

the URIDereferencer, or null if not specified

See Also:

XMLCryptoContext.setURIDereferencer(URIDereferencer)

setURIDereferencer

public void setURIDereferencer(URIDereferencer dereferencer)

Description copied from interface: XMLCryptoContext

Sets a URIDereferencer that is used to dereference URIReferences. The specified URIDereferencer is used in place of an implementation's default URIDereferencer.

Specified by:

setURIDereferencer in interface XMLCryptoContext

Parameters:

dereferencer - the URIDereferencer, or null to remove any current setting

See Also:

XMLCryptoContext.getURIDereferencer()

getProperty

Description copied from interface: XMLCryptoContext

Returns the value of the specified property.

Specified by:

getProperty in interface XMLCryptoContext

Parameters:

name - the name of the property

Returns:

the current value of the specified property, or null if it does not have a value

See Also:

get

public Object get(Object key)

Description copied from interface: XMLCryptoContext

Returns the value to which this context maps the specified key.

More formally, if this context contains a mapping from a key k to a value v such that (key==null ? k==null : key.equals(k)), then this method returns v; otherwise it returns null. (There can be at most one such mapping.)

This method is useful for retrieving arbitrary information that is specific to the cryptographic operation that this context is used for.

Specified by:

get in interface XMLCryptoContext

Parameters:

key - the key whose associated value is to be returned

Returns:

the value to which this context maps the specified key, or null if there is no mapping for the key

See Also:

XMLCryptoContext.put(Object, Object)

put

public Object put(Object key,
                  Object value)

Description copied from interface: XMLCryptoContext

Associates the specified value with the specified key in this context. If the context previously contained a mapping for this key, the old value is replaced by the specified value.

This method is useful for storing arbitrary information that is specific to the cryptographic operation that this context is used for.

Specified by:

put in interface XMLCryptoContext

Parameters:

key - key with which the specified value is to be associated with

value - value to be associated with the specified key

Returns:

the previous value associated with the key, or null if there was no mapping for the key

Throws:

IllegalArgumentException
