public class StandardCombiningAlgFactory

extends BaseCombiningAlgFactory

This factory supports the standard set of algorithms 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 algorithms, this factory does not allow the addition of any other algorithms. If you call addAlgorithm 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 BaseCombiningAlgFactory (or some other CombiningAlgFactory) and configure it with the standard algorithms using getStandardAlgorithms (or, in the case of BaseAttributeFactory, by providing the datatypes in the constructor).

Since:

1.2

Method Detail

getFactory

public static StandardCombiningAlgFactory 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 CombiningAlgFactory, ensuring quick access to this factory.

Returns:

the factory instance

getStandardAlgorithms

public Set getStandardAlgorithms()

Returns the set of algorithms that this standard factory supports.

Returns:

a Set of CombiningAlgorithms

addAlgorithm

public void addAlgorithm(CombiningAlgorithm alg)

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

Overrides:

addAlgorithm in class BaseCombiningAlgFactory

Parameters:

alg - the combining algorithm to add

Throws:

UnsupportedOperationException - always
