Methods Summary
public boolean	contains(double x, double y) Tests if the specified coordinates are inside the boundary of the Shape. param x the specified x coordinate param y the specified y coordinate return true if the specified coordinates are inside the Shape boundary; false otherwise.
public boolean	contains(java.awt.geom.Point2D p) Tests if a specified {@link Point2D} is inside the boundary of the Shape. param p a specified Point2D return true if the specified Point2D is inside the boundary of the Shape; false otherwise.
public boolean	contains(double x, double y, double w, double h) 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 rectanglar area to be considered contained within the Shape. This method might 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 this method might return false even though the Shape contains the rectangular area. The Area class can be used to perform more accurate computations of geometric intersection for any Shape object if a more precise answer is required. param x the x coordinate of the specified rectangular area param y the y coordinate of the specified rectangular area param w the width of the specified rectangular area param h the height of the specified rectangular area return true if the interior of the Shape entirely contains the specified rectangular area; false otherwise or, if the Shape contains the rectangular area and the intersects method returns true and the containment calculations would be too expensive to perform. see java.awt.geom.Area see #intersects
public boolean	contains(java.awt.geom.Rectangle2D r) Tests if the interior of the Shape entirely contains the specified Rectangle2D. This method might conservatively return false when: the intersect method returns true and the calculations to determine whether or not the Shape entirely contains the Rectangle2D are prohibitively expensive. This means that this method might return false even though the Shape contains the Rectangle2D. The Area class can be used to perform more accurate computations of geometric intersection for any Shape object if a more precise answer is required. param r The specified Rectangle2D return true if the interior of the Shape entirely contains the Rectangle2D; false otherwise or, if the Shape contains the Rectangle2D and the intersects method returns true and the containment calculations would be too expensive to perform. see #contains(double, double, double, double)
public java.awt.Rectangle	getBounds() Returns an integer {@link Rectangle} that completely encloses the Shape. Note that there is no guarantee that the returned Rectangle is the smallest bounding box that encloses the Shape, only that the Shape lies entirely within the indicated Rectangle. The returned Rectangle might also fail to completely enclose the Shape if the Shape overflows the limited range of the integer data type. The getBounds2D method generally returns a tighter bounding box due to its greater flexibility in representation. return an integer Rectangle that completely encloses the Shape. see #getBounds2D
public 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 {@link 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. return an instance of Rectangle2D that is a high-precision bounding box of the Shape. see #getBounds
public java.awt.geom.PathIterator	getPathIterator(java.awt.geom.AffineTransform at, double flatness) Returns an iterator object that iterates along the Shape boundary and provides access to a flattened view of the Shape outline geometry. Only SEG_MOVETO, SEG_LINETO, and SEG_CLOSE point types are returned by the iterator. If an optional AffineTransform is specified, the coordinates returned in the iteration are transformed accordingly. The amount of subdivision of the curved segments is controlled by the flatness parameter, which specifies the maximum distance that any point on the unflattened transformed curve can deviate from the returned flattened path segments. Note that a limit on the accuracy of the flattened path might be silently imposed, causing very small flattening parameters to be treated as larger values. This limit, if there is one, is defined by the particular implementation that is used. Each call to this method returns a fresh PathIterator object that traverses the Shape object geometry independently from any other PathIterator objects in use at the same time. It is recommended, but not guaranteed, that objects implementing the Shape interface isolate iterations that are in process from any changes that might occur to the original object's geometry during such iterations. Before using a particular implementation of this interface in more than one thread simultaneously, refer to its documentation to verify that it guarantees that iterations are isolated from modifications. param at an optional AffineTransform to be applied to the coordinates as they are returned in the iteration, or null if untransformed coordinates are desired param flatness the maximum distance that the line segments used to approximate the curved segments are allowed to deviate from any point on the original curve return a new PathIterator that independently traverses the Shape geometry.
public java.awt.geom.PathIterator	getPathIterator(java.awt.geom.AffineTransform at) Returns an iterator object that iterates along the Shape boundary and provides access to the geometry of the Shape outline. If an optional {@link AffineTransform} is specified, the coordinates returned in the iteration are transformed accordingly. Each call to this method returns a fresh PathIterator object that traverses the geometry of the Shape object independently from any other PathIterator objects in use at the same time. It is recommended, but not guaranteed, that objects implementing the Shape interface isolate iterations that are in process from any changes that might occur to the original object's geometry during such iterations. Before using a particular implementation of the Shape interface in more than one thread simultaneously, refer to its documentation to verify that it guarantees that iterations are isolated from modifications. param at an optional AffineTransform to be applied to the coordinates as they are returned in the iteration, or null if untransformed coordinates are desired return a new PathIterator object, which independently traverses the geometry of the Shape.
public boolean	intersects(double x, double y, double w, double h) Tests if the interior of the Shape intersects the interior of a specified rectangular area. The rectangular area is considered to intersect the Shape if any point is contained in both the interior of the Shape and the specified rectangular area. This method might conservatively return true when: there is a high probability that the rectangular area and the Shape intersect, but the calculations to accurately determine this intersection are prohibitively expensive. This means that this method might return true even though the rectangular area does not intersect the Shape. The {@link java.awt.geom.Area Area} class can be used to perform more accurate computations of geometric intersection for any Shape object if a more precise answer is required. param x the x coordinate of the specified rectangular area param y the y coordinate of the specified rectangular area param w the width of the specified rectangular area param h the height of the specified rectangular area return true if the interior of the Shape and the interior of the rectangular area intersect, or are both highly likely to intersect and intersection calculations would be too expensive to perform; false otherwise. see java.awt.geom.Area
public boolean	intersects(java.awt.geom.Rectangle2D r) Tests if the interior of the Shape intersects the interior of a specified Rectangle2D. This method might conservatively return true when: there is a high probability that the Rectangle2D and the Shape intersect, but the calculations to accurately determine this intersection are prohibitively expensive. This means that this method might return true even though the Rectangle2D does not intersect the Shape. param r the specified Rectangle2D return true if the interior of the Shape and the interior of the specified Rectangle2D intersect, or are both highly likely to intersect and intersection calculations would be too expensive to perform; false otherwise. see #intersects(double, double, double, double)
