CombiningAlgorithm

public CombiningAlgorithm(URI identifier)

Constructor that takes the algorithm's identifier.

Parameters:

identifier - the algorithm's identifier

Method Detail

combine

public abstract Result combine(EvaluationCtx context,
                               List inputs)

Combines the inputs based on the context to produce some unified result. This is the one function of a combining algorithm.

Parameters:

context - the representation of the request

inputs - the things to combine (policies or rules)

Returns:

a single unified result based on the combining logic

getIdentifier

public URI getIdentifier()

Returns the identifier for this algorithm.

Returns:

the algorithm's identifier
