Package org.djutils.draw.bounds

Interface Bounds<B extends Bounds<B,P,D>,P extends Point<P>,D extends Drawable<P>>

Type Parameters:

B - The bounds type (2d or 3d)

P - The point type (2d or 3d)

D - The Drawable type (2d or 3d)

All Known Implementing Classes:

Bounds2d, Bounds3d

public interface Bounds<B extends Bounds<B,P,D>,P extends Point<P>,D extends Drawable<P>>

Bounds is the generic tagging interface that indicates the bounds for an object, where the simplest implementation is minX, minY, maxX and maxY for 2D, and minX, minY, minZ and maxX, maxY and maxZ for 3D. Other bounds such as a BoundingCircle, BoundingSphere or BoundingPolytope could also be defined.

Method Detail

getMinX

double getMinX()

Return the absolute lower bound for x.

Returns:

double; the absolute lower bound for x

getMaxX

double getMaxX()

Return the absolute upper bound for x.

Returns:

double; the absolute upper bound for x

getMinY

double getMinY()

Return the absolute lower bound for y.

Returns:

double; the absolute lower bound for y

getMaxY

double getMaxY()

Return the absolute upper bound for y.

Returns:

double; the absolute upper bound for y

getDeltaX

default double getDeltaX()

Return the extent of this Bounds2d in the x-direction.

Returns:

double; the extent of this Bounds2d in the x-direction

getDeltaY

default double getDeltaY()

Return the extent of this Bounds2d in the y-direction.

Returns:

double; the extent of this Bounds2d in the y-direction

midPoint

P midPoint()

Return the mid point of this Bounds object.

Returns:

P; the mid point of this Bounds object

contains

boolean contains(P point)
          throws NullPointerException

Check if a point is contained in this Bounds.

Parameters:

point - P; the point

Returns:

boolean; true if the point is within this Bounds; false if the point is not within this Bounds, or on an edge of this Bounds

Throws:

NullPointerException - when point is null

contains

boolean contains(D drawable)
          throws NullPointerException

Check if this Bounds completely contains a Drawable. If any point of the Drawable lies on an edge (2d) or surface (3d) of this Bounds, this method returns false.

Parameters:

drawable - D; the object for which to check if it is completely contained within this Bounds.

Returns:

boolean; false if any point of D is on or outside one of the borders of this Bounds; true when all points of D are contained within this Bounds.

Throws:

NullPointerException - when drawable2d is null

covers

boolean covers(P point)
        throws NullPointerException

Check if this Bounds covers or touches a point.

Parameters:

point - P; the Point for which to check if it is covered/touched by this Bounds

Returns:

boolean; whether this Bounds covers or touches the point

Throws:

NullPointerException - when point is null

covers

boolean covers(D drawable)
        throws NullPointerException

Check if no part of a Drawable is outside this Bounds. The edges/surfaces of this Bounds are considered inside.

Parameters:

drawable - D; the Drawable for which to check if it is contained within this Bounds

Returns:

boolean; whether this Bounds contains the provided Bounds, including overlapping borders

Throws:

NullPointerException - when otherBounds is null

disjoint

boolean disjoint(D drawable)
          throws NullPointerException

Return whether a Drawable is disjoint from this Bounds. Only touching at an edge is considered disjoint. A Drawable that completely surrounds this Drawable is not disjoint.

Parameters:

drawable - D; the drawable

Returns:

boolean; true if the drawable is disjoint from this Bounds, or only touches an edge; false if any point of the drawable is inside this Bounds, or the drawable surrounds this Bounds

Throws:

NullPointerException - when bounds is null

intersects

boolean intersects(B otherBounds)

Return whether this Bounds intersects another Bounds. Only touching at an edge is not seen as intersecting.

Parameters:

otherBounds - B; the other Bounds

Returns:

boolean; whether this bounding box/rectangle intersects the other Bounds

Throws:

NullPointerException - when otherBounds is null

intersection

B intersection(B otherBounds)

Return the intersecting Bounds of this Bounds and another Bounds. Touching at the edge is not seen as intersecting. In case there is no intersection, null is returned.

Parameters:

otherBounds - B; the other Bounds

Returns:

Bounds; the intersecting Bounds of this Bounds and another Bounds. Touching at the edge is not seen as intersecting. If not intersecting; null is returned

Throws:

NullPointerException - when otherBounds is null
