This version of 2D point uses double precision fields to save the value of each component. It is meant for garbage free usage.
| Constructor | Description |
|---|---|
Point2D() |
Creates a new point and initializes it coordinates to zero.
|
Point2D(double[] pointArray) |
Creates a new point and initializes its component
x, y in order from the given
array. |
Point2D(double x,
double y) |
Creates a new point and initializes it with the given coordinates.
|
Point2D(Tuple2DReadOnly other) |
Creates a new point and initializes it to
other. |
Point2D(Tuple3DReadOnly tuple3DReadOnly) |
Creates a new point and initializes it to
tuple3DReadOnly x and y components. |
| Modifier and Type | Method | Description |
|---|---|---|
boolean |
epsilonEquals(Point2D other,
double epsilon) |
Tests on a per component basis if this point is equal to the given
other to an
epsilon. |
boolean |
equals(java.lang.Object object) |
Tests if the given
object's class is the same as this, in which case the method
returns Tuple2DReadOnly.equals(Tuple2DReadOnly), it returns false otherwise. |
boolean |
geometricallyEquals(Point2D other,
double epsilon) |
Tests if
this and other represent the same point 2D to an epsilon. |
double |
getX() |
Returns the value of the x-coordinate of this point.
|
double |
getY() |
Returns the value of the y-coordinate of this point.
|
int |
hashCode() |
Calculates and returns a hash code value from the value of each component of this point 2D.
|
void |
set(Point2D other) |
Sets this point to
other. |
void |
setX(double x) |
Sets the x-coordinate of this point.
|
void |
setY(double y) |
Sets the y-coordinate of this point.
|
java.lang.String |
toString() |
Provides a
String representation of this point 2D as follows: (x, y). |

this and other represent the same point 2D to an epsilon.
Two points are considered geometrically equal if they are at a distance of less than or equal
to epsilon.
Note that this.geometricallyEquals(other, epsilon) == true does not necessarily imply
this.epsilonEquals(other, epsilon) and vice versa.
