Interface XMLCryptoContext

public interface XMLCryptoContext

Contains common context information for XML cryptographic operations.

This interface contains methods for setting and retrieving properties that affect the processing of XML signatures or XML encrypted structures.

Note that XMLCryptoContext instances can contain information and state specific to the XML cryptographic structure it is used with. The results are unpredictable if an XMLCryptoContext is used with multiple structures (for example, you should not use the same XMLValidateContext instance to validate two different XMLSignature objects).

Methods

getBaseURI

String getBaseURI()

Returns the base URI.

Returns:

the base URI, or null if not specified

See Also:

setBaseURI(String)

setBaseURI

void setBaseURI(String baseURI)

Sets the base URI.

Parameters:

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

Throws:

IllegalArgumentException - if baseURI is not RFC 2396 compliant

See Also:

getBaseURI()

getKeySelector

KeySelector getKeySelector()

Returns the key selector for finding a key.

Returns:

the key selector, or null if not specified

See Also:

setKeySelector(KeySelector)

setKeySelector

void setKeySelector(KeySelector ks)

Sets the key selector for finding a key.

Parameters:

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

See Also:

getKeySelector()

getURIDereferencer

URIDereferencer getURIDereferencer()

Returns a URIDereferencer that is used to dereference URIReferences.

Returns:

the URIDereferencer, or null if not specified

See Also:

setURIDereferencer(URIDereferencer)

setURIDereferencer

void setURIDereferencer(URIDereferencer dereferencer)

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

Parameters:

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

See Also:

getURIDereferencer()

getNamespacePrefix

String getNamespacePrefix(String namespaceURI,
                          String defaultPrefix)

Returns the namespace prefix that the specified namespace URI is associated with. Returns the specified default prefix if the specified namespace URI has not been bound to a prefix. To bind a namespace URI to a prefix, call the putNamespacePrefix method.

Parameters:

namespaceURI - a namespace URI

defaultPrefix - the prefix to be returned in the event that the the specified namespace URI has not been bound to a prefix.

Returns:

the prefix that is associated with the specified namespace URI, or defaultPrefix if the URI is not registered. If the namespace URI is registered but has no prefix, an empty string ("") is returned.

Throws:

NullPointerException - if namespaceURI is null

See Also:

putNamespacePrefix(String, String)

putNamespacePrefix

String putNamespacePrefix(String namespaceURI,
                          String prefix)

Maps the specified namespace URI to the specified prefix. If there is already a prefix associated with the specified namespace URI, the old prefix is replaced by the specified prefix.

Parameters:

namespaceURI - a namespace URI

prefix - a namespace prefix (or null to remove any existing mapping). Specifying the empty string ("") binds no prefix to the namespace URI.

Returns:

the previous prefix associated with the specified namespace URI, or null if there was none

Throws:

NullPointerException - if namespaceURI is null

See Also:

getNamespacePrefix(String, String)

getDefaultNamespacePrefix

String getDefaultNamespacePrefix()

Returns the default namespace prefix. The default namespace prefix is the prefix for all namespace URIs not explicitly set by the putNamespacePrefix method.

Returns:

the default namespace prefix, or null if none has been set.

See Also:

setDefaultNamespacePrefix(String)

setDefaultNamespacePrefix

void setDefaultNamespacePrefix(String defaultPrefix)

Sets the default namespace prefix. This sets the namespace prefix for all namespace URIs not explicitly set by the putNamespacePrefix method.

Parameters:

defaultPrefix - the default namespace prefix, or null to remove the current setting. Specify the empty string ("") to bind no prefix.

See Also:

getDefaultNamespacePrefix()

setProperty

Object setProperty(String name,
                   Object value)

Sets the specified property.

Parameters:

name - the name of the property

value - the value of the property to be set

Returns:

the previous value of the specified property, or null if it did not have a value

Throws:

NullPointerException - if name is null

See Also:

getProperty(String)

getProperty

Object getProperty(String name)

Returns the value of the specified property.

Parameters:

name - the name of the property

Returns:

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

Throws:

NullPointerException - if name is null

See Also:

setProperty(String, Object)

get

Object get(Object key)

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:

put(Object, Object)

put

Object put(Object key,
           Object value)

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 - if some aspect of this key or value prevents it from being stored in this context

get(Object)
