Constructor Detail

DoubleRectangle

public DoubleRectangle(double _x,
                       double _y,
                       double _width,
                       double _height)

Constructor.

Parameters:

_x - - the x coordinate of the closest to the reference point (0, 0) summit of the rectangle

_y - - the y coordinate of the closest to the reference point (0, 0) summit of the rectangle

_width - - the width of the rectangle

_height - - the height of the rectangle

DoubleRectangle

public DoubleRectangle(DoublePoint _topLeft,
                       DoublePoint _bottomRight)

Constructor

Parameters:

_topLeft - - coordinates of the closest to the reference point summit of the rectangle

_bottomRight - - coordinates of the opposite to the _topLeft summit of the rectangle

Method Detail

toString

public java.lang.String toString()

Returns the string representation of the current object

Overrides:

toString in class java.lang.Object

equals

public boolean equals(DoubleRectangle _drct)

Compares the current object with the given one. Two DoubleRectangles are equals each other if they have similar fields values.

Parameters:

_drct - - the DoubleRectangle to compare the current object with

move

public void move(double _x,
                 double _y)

Moves the current object to the given point.

Parameters:

_x - - the x coordinate of the closest to the refernce point summit of the current object

_y - - the y coordinate of the closest to the reference point summit of the current object

move

public void move(DoublePoint _dpt)

Moves the current object to the given point.

Parameters:

_dpt - - new coordinates of the closest to the refernce point summit of the current object

translate

public void translate(double _dx,
                      double _dy)

Translates the current object by the given vector

Parameters:

_dx - - displacement of the x coordinate of the current object

_dy - - displacement of the y coordinate of the current object

translate

public void translate(DoublePoint _dpt)

Translates the current object by the given vector

Parameters:

_dpt - - displacement of coordinates of the current object

intersect

public DoubleRectangle intersect(DoubleRectangle _rct)

Returns the intersection of the current object with the given DoubleRectangle

Parameters:

_rct - - gicen DoubleRectangle

contains

public boolean contains(DoublePoint _dpt)

Returns true if the given point is in the given object. Returns false otherwize.

Parameters:

_dpt - - the given point

normilize

public void normilize()

Converts the current object to the "normal" state. I.e. the values of width and height fields are to be >= 0.
