Method Detail

iterator

public Iterator<Map.Entry<T,Value<?>>> iterator()

Specified by:

iterator in interface Iterable<T extends Criterion>

array

public abstract double[] array()

Returns an array of all CriterionSet values.

Returns:

an array containing CriterionSet values

size

public int size()

Returns the number of set Criterions.

Returns:

the number of set Criterions

getKeys

public Collection<T> getKeys()

Returns all Criterions.

Returns:

all Criterions

getValues

public Collection<Value<?>> getValues()

Returns all values.

Returns:

all values

get

public Value<?> get(T criterion)

Returns the value that is assigned to the given Criterion. Returns null if the Criterion does not exist.

Parameters:

criterion - the given criterion

Returns:

the value

get

public T get(Value<?> value)

Returns the Criterion that is assigned to the given value. Returns null if the value does not exist.

Parameters:

value - the given value

Returns:

the Criterion

add

public void add(T criterion,
                Value<?> value)

Adds the Criterion with the specified value.

Parameters:

criterion - the criterion

value - the value

add

public void add(T criterion,
                double value)

Adds the Criterion with the specified double value.

Parameters:

criterion - the criterion

value - the value

add

public void add(T criterion,
                int value)

Adds the Criterion with the specified integer value.

Parameters:

criterion - the criterion

value - the value

add

public void add(CriterionSet<T> criterionSet)

Adds all Criterions with the specified value specified in criterionSet.

Parameters:

criterionSet - the criterionSet

isEqual

public boolean isEqual(CriterionSet<T> opponent)

Returns true if this CriterionSet is equal to the specified CriterionSet. This comparison is based on the #array() values.

Parameters:

opponent - other CriterionSet

Returns:

true if the CriterionSets are equal

distance

public double distance(CriterionSet<T> other)

Calculates the euclidean distance of two CriterionSets. This calculation is based on the #array() values.

Parameters:

other - the second CriterionSet

Returns:

the euclidean distance
