Constructor Detail

PerformanceComparator

public PerformanceComparator(int evaluation,
                             AbstractEvaluationMetrics metrics)

initializes the comparator with the given performance measure.

Parameters:

evaluation - the performance measure to use

metrics - the metrics to use

Method Detail

getEvaluation

public int getEvaluation()

returns the performance measure that's used to compare the objects.

Returns:

the performance measure

getMetrics

public AbstractEvaluationMetrics getMetrics()

Returns the metrics in use.

Returns:

the metrics

compare

public int compare(Performance o1,
                   Performance o2)

Compares its two arguments for order. Returns a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.

Specified by:

compare in interface Comparator<Performance>

Parameters:

o1 - the first performance

o2 - the second performance

Returns:

the order

equals

public boolean equals(Object obj)

Indicates whether some other object is "equal to" this Comparator.

Specified by:

equals in interface Comparator<Performance>

Overrides:

equals in class Object

Parameters:

obj - the object to compare with

Returns:

true if the same evaluation type is used
