Constructor that takes the algorithm's identifier.

Parameters:

identifier - the algorithm's identifier

Method Detail

combine

public abstract AbstractResult combine(EvaluationCtx context,
                                       List parameters,
                                       List ruleElements)

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

Specified by:

combine in class CombiningAlgorithm

Parameters:

context - the representation of the request

parameters - a (possibly empty) non-null List of CombinerParameters

ruleElements - a List of CombinerElements

Returns:

a single unified result based on the combining logic
