public boolean contains(double x,
                        double y)

Specified by:

contains in interface java.awt.Shape

contains

public boolean contains(double x,
                        double y,
                        double w,
                        double h)

Specified by:

intersects

public boolean intersects(double x,
                          double y,
                          double w,
                          double h)

Specified by:

getBounds

public java.awt.Rectangle getBounds()

Specified by:

getBounds in interface java.awt.Shape

contains

public boolean contains(java.awt.geom.Point2D p)

Specified by:

contains in interface java.awt.Shape

getBounds2D

public java.awt.geom.Rectangle2D getBounds2D()

Specified by:

getBounds2D in interface java.awt.Shape

contains

public boolean contains(java.awt.geom.Rectangle2D r)

Specified by:

contains in interface java.awt.Shape

intersects

public boolean intersects(java.awt.geom.Rectangle2D r)

El método intersects de java.awt.Shape que define la intersección entre una polilínea y un Rectangle2D considera la polilínea como un Shape genérico y se producen errores en la selección de polilíneas. Por este motivo se ha modificado este método intersect() de FPolyline2D para que realize la intersección estricta entre el Rectangle2D y la polilínea en cuestión. El precio es un incremento de tiempo máximo del 50%.

Specified by:

intersects in interface java.awt.Shape

Parameters:

r - Rectángulo.

Returns:

True si intersecta con el rectangulo que se pasa como parámetro.

getPathIterator

public java.awt.geom.PathIterator getPathIterator(java.awt.geom.AffineTransform at)

Specified by:

getPathIterator in interface java.awt.Shape

getPathIterator

public java.awt.geom.PathIterator getPathIterator(java.awt.geom.AffineTransform at,
                                                  double flatness)

Specified by:

getPathIterator in interface java.awt.Shape
