Constructor Detail

BoundingBox

public BoundingBox(double l,
           double t,
           double r,
           double b)

Constructor for a bounding box. All coordinates are inclusive.

Parameters:

l - leftmost x-coordinate

t - topmost y-coordinate

r - rightmost x-coordinate

b - bottommost y-coordinate

Method Detail

intersectDestructively

public boolean intersectDestructively(BoundingBox bb)

Determines whether this bounding box intersects with the passed bounding box and, if so, mutates the bounding box to be the intersection. This was designed to behave the same as Rect.intersect(android.graphics.Rect).

Parameters:

bb - bounding box to intersect with this bounding box

Returns:

true if they intersect, false otherwise

getLeft

public double getLeft()

Gets the leftmost x-coordinate

Returns:

the leftmost x-coordinate

getTop

public double getTop()

Gets the uppermost y-coordinate

Returns:

the uppermost y-coordinate

getRight

public double getRight()

Gets the rightmost x-coordinate

Returns:

the rightmost x-coordinate

getBottom

public double getBottom()

Gets the bottommost y-coordinate

Returns:

the bottommost y-coordinate

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
