Constructor Details

FractionValue

public FractionValue(Metric metric,
 org.apache.commons.lang3.math.Fraction fraction)

Creates a new FractionValue with the specified value for the given metric.

Parameters:

metric - the coverage metric

fraction - the value to store

FractionValue

public FractionValue(Metric metric,
 int numerator,
 int denominator)

Creates a new FractionValue from the specified counters for the given metric.

Parameters:

metric - the coverage metric

numerator - the numerator of the rational number

denominator - the denominator of the rational number

Method Details

getFraction

public org.apache.commons.lang3.math.Fraction getFraction()

add

public Value add(Value other)

Description copied from class: Value

Add the coverage from the specified instance to the coverage of this instance.

Specified by:

add in class Value

Parameters:

other - the additional coverage details

Returns:

the sum of this and the additional coverage

delta

public org.apache.commons.lang3.math.Fraction delta(Value other)

Description copied from class: Value

Computes the delta of this value with the specified value.

Specified by:

delta in class Value

Parameters:

other - the value to compare with

Returns:

the delta of this and the additional value

max

public Value max(Value other)

Description copied from class: Value

Merge this coverage with the specified coverage.

Specified by:

max in class Value

Parameters:

other - the other coverage

Returns:

the merged coverage

isOutOfValidRange

public boolean isOutOfValidRange(double threshold)

Returns whether this fraction is out of the valid range. For values that have a metric that is getting better when values are increasing (e.g., coverage), the method will return true if the fraction value is smaller than the threshold. For values that have a metric that is getting better when values are decreasing (e.g., complexity), the method will return true if the fraction value is larger than the threshold.

Specified by:

isOutOfValidRange in class Value

Parameters:

threshold - the threshold to compare with

Returns:

true, if this value is larger or smaller than specified threshold (see Metric.MetricTendency)

toString

public String toString()

Overrides:

toString in class Object

serialize

public String serialize()

Description copied from class: Value

Serializes this instance into a String.

Specified by:

serialize in class Value

Returns:

a String serialization of this value

equals

public boolean equals(Object o)

Overrides:

equals in class Value

hashCode

public int hashCode()

Overrides:

hashCode in class Value
