intersectStrict

public final Bounds intersectStrict(Bounds b)

Get intersection with another Bounds. This version treats intervals [n,n] as empty, which is necessary for intersections in scheduling where "a meets b" should not create a conflict.

Parameters:

b - The Bounds object to intersect this with.

Returns:

true is there is a non-empty intersection, null otherwise.

isIntersecting

public boolean isIntersecting(Bounds b)

Returns true iff this Bounds intersects with a given Bounds.

Parameters:

b - The Bounds to check against.

Returns:

true iff this Bounds intersects with a given Bounds.

intersect

public final Bounds intersect(Bounds b)

Get intersection with another Bounds.

Parameters:

b - The Bounds object to intersect this with.

Returns:

true is there is a non-empty intersection, null otherwise.

union

public static Bounds union(Bounds... b)

compareTo

public int compareTo(Bounds o)

Specified by:

compareTo in interface java.lang.Comparable<Bounds>
