Constructor Detail

MappedAnalytic

public MappedAnalytic(InputMapper<I,A,MI> inputMapper,
              OutputMapper<I,O,A,MO> outputMapper)

Creates a new MappedAnalytic.

Parameters:

inputMapper - must not be null.

outputMapper - must not be null.

Method Detail

evaluate

public O evaluate(I input)

Evaluates the encoded Analytic against the given input. The inputMapper is used to map the given input to an appropriate input for the internal evaluation of the Analytic. The resulting output of internal evaluation is mapped via the outputMapper to an appropriate result.

Specified by:

evaluate in interface Analytic<I,O>

Parameters:

input - must not be null

Returns:

the evaluation result

evaluateInternal

protected abstract MO evaluateInternal(MI modelInput)

Performs the actual evaluation with the mapped input values.

Parameters:

modelInput - must not be null

Returns:

the unmapped actual output of the internal evaluation.
