Class StandardAttributeFactory

public class StandardAttributeFactory

extends BaseAttributeFactory

This factory supports the standard set of datatypes specified in XACML 1.0 and 1.1. It is the default factory used by the system, and imposes a singleton pattern insuring that there is only ever one instance of this class.

Note that because this supports only the standard datatypes, this factory does not allow the addition of any other datatypes. If you call addDatatype on an instance of this class, an exception will be thrown. If you need a standard factory that is modifiable, you should create a new BaseAttributeFactory (or some other AttributeFactory) and configure it with the standard datatypes using addStandardDatatypes (or, in the case of BaseAttributeFactory, by providing the datatypes in the constructor).

Since:

1.2

Method Detail

getFactory

public static StandardAttributeFactory getFactory()

Returns an instance of this factory. This method enforces a singleton model, meaning that this always returns the same instance, creating the factory if it hasn't been requested before. This is the default model used by the AttributeFactory, ensuring quick access to this factory.

Returns:

the factory instance

getStandardDatatypes

public Map getStandardDatatypes()

Returns the set of datatypes that this standard factory supports.

Returns:

a Map of String to AttributeProxys

addDatatype

public void addDatatype(String id,
                        AttributeProxy proxy)

Throws an UnsupportedOperationException since you are not allowed to modify what a standard factory supports.

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

Throws:

UnsupportedOperationException - always
