Constructor Detail

Interval

public Interval(int start,
                int end)

Contructor. For interval holds 0 <= start < end.

Parameters:

start - of interval, must be non-negative

end - of interval, greater than start, is not included in interval

Method Detail

getStart

public int getStart()

Returns starting index.

Returns:

starting index

getEnd

public int getEnd()

Returns ending index.

Returns:

ending index

contains

public boolean contains(int index)

Tests if index falls into interval (into or onto bounds)

Parameters:

index - to test

Returns:

true if index is inside of this interval

contains

public boolean contains(Interval interval)

Tests if this interval contains interval.

Parameters:

interval - Interval to test

Returns:

true if interval is inside this interval

intersects

public boolean intersects(Interval interval)

Tests if this interval intersects interval.

Parameters:

interval - Interval to test for inersection

Returns:

true if their intersection is not empty or they are adjacent

ORIntervals

public static Interval ORIntervals(Interval interval1,
                                   Interval interval2)

Computes OR of two intervals. Interval to OR have to intersect.

Parameters:

interval1 -

interval2 -

Returns:

logical OR of this intersecting intervals

toString

public String toString()

Overrides:

toString in class Object
