Interface Envelope

All Known Implementing Classes:

EnvelopeImpl, LayerBoundingBox

public interface Envelope

a boundingbox as child of a Polygon isn't part of the iso19107 spec but it simplifies the geometry handling

boolean	contains(Position position) returns true if the bounding box contains the submitted position
Envelope	createIntersection(Envelope bb) returns a new Envelope object representing the intersection of this Envelope with the specified Envelope.
void	expandToContain(Envelope other) ensures that the passed Envepole is contained within this.Envelope
Envelope	getBuffer(double b) creates a new envelope
Point	getCentroid() returns the centroid of an Envelope
CoordinateSystem	getCoordinateSystem() returns the spatial reference system of a geometry
double	getHeight() returns the height of bounding box
Position	getMax() returns the maximum coordinates of bounding box
Position	getMin() returns the minimum coordinates of bounding box
double	getWidth() returns the width of bounding box
boolean	intersects(Envelope bb) returns true if this envelope intersects the submitted envelope
Envelope	merge(Envelope envelope) merges two Envelops and returns the minimum envelope containing both.
Envelope	translate(double x, double y) translate a envelope in the direction defined by the two passed values and retiurns the resulting envelope

Method Detail

getCoordinateSystem

CoordinateSystem getCoordinateSystem()

the spatial reference system of a geometry

getWidth

double getWidth()

returns the width of bounding box

Returns:

the width of bounding box

getHeight

double getHeight()

returns the height of bounding box

the height of bounding box

getMin

Position getMin()

returns the minimum coordinates of bounding box

Returns:

the minimum coordinates of bounding box

getMax

Position getMax()

returns the maximum coordinates of bounding box

Returns:

the maximum coordinates of bounding box

contains

boolean contains(Position position)

returns true if the bounding box contains the submitted position

Parameters:

position - the position to find

Returns:

true if the bounding box contains the submitted position

intersects

boolean intersects(Envelope bb)

returns true if this envelope intersects the submitted envelope

Parameters:

bb - another Envelope

Returns:

true if this envelope intersects the submitted envelope

contains

boolean contains(Envelope bb)

returns true if all positions of the submitted bounding box are within this bounding box

Parameters:

bb - another boundingbox

true if all positions of the submitted bounding box are within this bounding box

createIntersection

Envelope createIntersection(Envelope bb)

returns a new Envelope object representing the intersection of this Envelope with the specified Envelope.

Parameters:

bb - another boundingbox

Returns:

a new Envelope object representing the intersection of this Envelope with the specified Envelope.

merge

Envelope merge(Envelope envelope)
               throws GeometryException

merges two Envelops and returns the minimum envelope containing both.

Parameters:

envelope - another envelope to merge with this one

Returns:

the minimum envelope containing both.

Throws:

GeometryException - if the coordinatesystems are not equal

getBuffer

Envelope getBuffer(double b)

creates a new envelope

Parameters:

b - an extra bound around the Envelope

Returns:

a new Envelope

expandToContain

void expandToContain(Envelope other)

ensures that the passed Envepole is contained within this.Envelope

Parameters:

other - to expand this Envelope.

translate

Envelope translate(double x,
                   double y)

translate a envelope in the direction defined by the two passed values and retiurns the resulting envelope

Parameters:

x - coordinate

y - coordinate

Returns:

the resulting translated Envelope

getCentroid

Point getCentroid()

returns the centroid of an Envelope

Returns:

centroid of an Envelope
