Method Detail

add back to summary

add	back to summary
public void add(double newx, double newy) Adds a point, specified by the double precision arguments `newx` and `newy`, to this `Rectangle2D`. The resulting `Rectangle2D` is the smallest `Rectangle2D` that contains both the original `Rectangle2D` and the specified point. After adding a point, a call to `contains` with the added point as an argument does not necessarily return `true`. The `contains` method does not return `true` for points on the right or bottom edges of a rectangle. Therefore, if the added point falls on the right or bottom edge of the enlarged rectangle, `contains` returns `false` for that point. Parameters newx:double the X coordinate of the new point newy:double the Y coordinate of the new point Since 1.2

public void add(double newx, double newy)

Adds a point, specified by the double precision arguments newx and newy, to this Rectangle2D. The resulting Rectangle2D is the smallest Rectangle2D that contains both the original Rectangle2D and the specified point.

After adding a point, a call to contains with the added point as an argument does not necessarily return true. The contains method does not return true for points on the right or bottom edges of a rectangle. Therefore, if the added point falls on the right or bottom edge of the enlarged rectangle, contains returns false for that point.

Parameters

newx:double: the X coordinate of the new point
newy:double: the Y coordinate of the new point

The resulting `Rectangle2D` is the smallest `Rectangle2D` that contains both the original `Rectangle2D` and the specified `Point2D`. After adding a point, a call to `contains` with the added point as an argument does not necessarily return `true`. The `contains` method does not return `true` for points on the right or bottom edges of a rectangle. Therefore, if the added point falls on the right or bottom edge of the enlarged rectangle, `contains` returns `false` for that point. Parameters pt:Point2D the new `Point2D` to add to this `Rectangle2D`. Since 1.2

public void add(Point2D pt)

contains	back to summary
public boolean contains(double x, double y, double w, double h) Implements java.awt.Shape.contains. Doc from java.awt.Shape.contains. Tests if the interior of the `Shape` entirely contains the specified rectangular area. All coordinates that lie inside the rectangular area must lie within the `Shape` for the entire rectangular area to be considered contained within the `Shape`. The `Shape.contains()` method allows a `Shape` implementation to conservatively return `false` when: the `intersect` method returns `true` and the calculations to determine whether or not the `Shape` entirely contains the rectangular area are prohibitively expensive. This means that for some `Shapes` this method might return `false` even though the `Shape` contains the rectangular area. The `Area` class performs more accurate geometric computations than most `Shape` objects and therefore can be used if a more precise answer is required. Since 1.2

getBounds2D back to summary

getBounds2D	back to summary
public Rectangle2D getBounds2D() Implements java.awt.Shape.getBounds2D. Doc from java.awt.Shape.getBounds2D. Returns a high precision and more accurate bounding box of the `Shape` than the `getBounds` method. Note that there is no guarantee that the returned `Rectangle2D` is the smallest bounding box that encloses the `Shape`, only that the `Shape` lies entirely within the indicated `Rectangle2D`. The bounding box returned by this method is usually tighter than that returned by the `getBounds` method and never fails due to overflow problems since the return value can be an instance of the `Rectangle2D` that uses double precision values to store the dimensions. Note that the definition of insideness can lead to situations where points on the defining outline of the `shape` may not be considered contained in the returned `bounds` object, but only in cases where those points are also not considered contained in the original `shape`. If a `point` is inside the `shape` according to the `contains(point)` method, then it must be inside the returned `Rectangle2D` bounds object according to the `contains(point)` method of the `bounds`. Specifically: `shape.contains(p)` requires `bounds.contains(p)` If a `point` is not inside the `shape`, then it might still be contained in the `bounds` object: `bounds.contains(p)` does not imply `shape.contains(p)` Since 1.2

public Rectangle2D getBounds2D()

Returns a high precision and more accurate bounding box of the Shape than the getBounds method.

If a point is inside the shape according to the contains(point) method, then it must be inside the returned Rectangle2D bounds object according to the contains(point) method of the bounds. Specifically:

shape.contains(p) requires bounds.contains(p)

If a point is not inside the shape, then it might still be contained in the bounds object:

bounds.contains(p) does not imply shape.contains(p)

getBounds2D back to summary

getBounds2D	back to summary
public Rectangle2D getBounds2D() Overrides java.awt.geom.Rectangle2D.getBounds2D. Implements java.awt.Shape.getBounds2D. Doc from java.awt.geom.Rectangle2D.getBounds2D. Returns a high precision and more accurate bounding box of the `Shape` than the `getBounds` method. Note that there is no guarantee that the returned `Rectangle2D` is the smallest bounding box that encloses the `Shape`, only that the `Shape` lies entirely within the indicated `Rectangle2D`. The bounding box returned by this method is usually tighter than that returned by the `getBounds` method and never fails due to overflow problems since the return value can be an instance of the `Rectangle2D` that uses double precision values to store the dimensions. Note that the definition of insideness can lead to situations where points on the defining outline of the `shape` may not be considered contained in the returned `bounds` object, but only in cases where those points are also not considered contained in the original `shape`. If a `point` is inside the `shape` according to the `contains(point)` method, then it must be inside the returned `Rectangle2D` bounds object according to the `contains(point)` method of the `bounds`. Specifically: `shape.contains(p)` requires `bounds.contains(p)` If a `point` is not inside the `shape`, then it might still be contained in the `bounds` object: `bounds.contains(p)` does not imply `shape.contains(p)` Since 1.2
