Method Detail

addDatatype

public void addDatatype(String id,
               AttributeProxy proxy)

Description copied from class: BaseAttributeFactory

Adds a proxy to the factory, which in turn will allow new attribute types to be created using the factory. Typically the proxy is provided as an anonymous class that simply calls the getInstance methods (or something similar) of some AttributeValue class.

Overrides:

addDatatype in class BaseAttributeFactory

Parameters:

id - the name of the attribute type

proxy - the proxy used to create new attributes of the given type

createValue

public AttributeValue createValue(URI dataType,
                         String value)
                           throws UnknownIdentifierException,
                                  ParsingException

Description copied from class: BaseAttributeFactory

Creates a value based on the given data type and text-encoded value. Used primarily by code that does an XPath query to get an attribute value, and then needs to turn the resulting value into an Attribute class.

Overrides:

createValue in class BaseAttributeFactory

Parameters:

dataType - the type of the attribute

value - the text-encoded representation of an attribute's value

Returns:

a new AttributeValue

Throws:

UnknownIdentifierException - if the data type isn't known to the factory

ParsingException - if the text is invalid or can't be parsed by the appropriate proxy

createValue

public AttributeValue createValue(Node root,
                         String type)
                           throws UnknownIdentifierException,
                                  ParsingException

Description copied from class: BaseAttributeFactory

Creates a value based on the given DOM root node and data type.

Overrides:

createValue in class BaseAttributeFactory

Parameters:

root - the DOM root of an attribute value

type - the type of the attribute

Returns:

a new AttributeValue

Throws:

UnknownIdentifierException - if the type isn't known to the factory

ParsingException - if the node is invalid or can't be parsed by the appropriate proxy

createValue

public AttributeValue createValue(Node root,
                         URI dataType)
                           throws UnknownIdentifierException,
                                  ParsingException

Description copied from class: BaseAttributeFactory

Creates a value based on the given DOM root node and data type.

Overrides:

createValue in class BaseAttributeFactory

Parameters:

root - the DOM root of an attribute value

dataType - the type of the attribute

Returns:

a new AttributeValue

Throws:

UnknownIdentifierException - if the data type isn't known to the factory

ParsingException - if the node is invalid or can't be parsed by the appropriate proxy

getFactory

public static ExtendedAttributeFactory getFactory()
