All Implemented Interfaces:

Serializable, Iterable<Interval>

public class MultiInterval
extends Object
implements Iterable<Interval>, Serializable

A class representing (possibly) multiple intervals. This can be used to specify any combination of values to be included in an interval. The MultiInterval is built up by specifying normal intervals to be included or excluded from the MultiInterval.

Constructor Detail

MultiInterval

public MultiInterval()

Default constructor. Constructs an empty MultiInterval containing no values. Note that if the first operation called on this interval after its construction is exclude(), all values except the ones excluded will be included in this interval.

Method Detail

include

public void include(Interval interval)

Add an interval to be included in this MultiInterval.

Parameters:

interval - An interval specifying values to be included in this MultiInterval.

exclude

public void exclude(Interval interval)

Exclude a specific interval from this MultiInterval. If this MultiInterval is empty (i.e. does not include anything) when this function is called, the MultiInterval will accept any value except the ones included in the interval specified.

Parameters:

interval - an interval specifying which values to exclude from this MultiInterval.

contains

public boolean contains(double value)

Check if a value is contained in this MultiInterval.

NOTE: Infinity and NaN is never reported to be included in a MultiInterval.

Parameters:

value - The value to check for.

Returns:

true if the value has been specified to be included in this MultiInterval, false otherwise.

negate

public static MultiInterval negate(MultiInterval term)

Calculates a negation av a MultiInterval

Parameters:

term - is the MultiInterval to be negated

Returns:

the negated MultiInterval

add

public static MultiInterval add(MultiInterval term1,
                MultiInterval term2)

Calculates the sum of two MultiIntervals

Parameters:

term1 - is the first term

term2 - is the second term

Returns:

the summarized MultiIntervals

sub

public static MultiInterval sub(MultiInterval term1,
                MultiInterval term2)

Calculates the difference of two MultiIntervals

Parameters:

term1 - is the first term

term2 - is the second term

Returns:

the difference of the two MultiIntervals

mul

public static MultiInterval mul(MultiInterval factor1,
                MultiInterval factor2)

Calculates the product of two MultiIntervals

Parameters:

factor1 - is the first factor

factor2 - is the second factor

Returns:

the product of thw two MultiIntervals

div
