Methodendetails

evaluateSample

public void evaluateSample(T sample)

Evaluates the given reference object. The default implementation calls processSample(Object)

note: this method will be changed to private in the future. Implementations should override processSample(Object) instead. If this method is overridden, the implementation has to update the score after every invocation.

Parameter:

sample - A sample to be evaluated.

evaluate

public void evaluate(ObjectStream<T> samples)
              throws IOException

Reads all sample objects and evaluates each instance via the evaluateSample(Object) method.

Parameter:

samples - The stream of reference which shall be evaluated.

Löst aus:

IOException - Thrown if IO errors occurred.
