Field Summary

int	height The height in pixel.
int	width The width in pixel.
int	x The x pixel position.
int	y The y pixel position.

Constructor Summary

RasterRect()
Creates a new RasterRect with position 0, 0 and size 0, 0.

RasterRect(int x, int y, int width, int height)
Creates a new RasterRect

RasterRect(RasterRect rasterRect)

RasterRect(Rectangle rect)

Method Summary

boolean	equals(Object other)
int	hashCode() Implementation as proposed by Joshua Block in Effective Java (Addison-Wesley 2001), which supplies an even distribution and is relatively fast.
static RasterRect	intersection(RasterRect first, RasterRect second) Create an intersection of the given RasterRects, if the given rasterects do not intersect, null will be returned.

width

public int width

The width in pixel.

height

public int height

The height in pixel.

Constructor Detail

RasterRect

public RasterRect(int x,
                  int y,
                  int width,
                  int height)

Creates a new RasterRect

Parameters:

x - upper-left pixel

y - upper-left pixel

width - width of rectangle

height - height of rectangle

RasterRect

public RasterRect()

Creates a new RasterRect with position 0, 0 and size 0, 0.

RasterRect

public RasterRect(Rectangle rect)

Parameters:

rect - to copy data of.

RasterRect

public RasterRect(RasterRect rasterRect)

Parameters:

rasterRect - to copy data of

Method Detail

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Implementation as proposed by Joshua Block in Effective Java (Addison-Wesley 2001), which supplies an even distribution and is relatively fast. It is created from field f as follows:

• boolean -- code = (f ? 0 : 1)
• byte, char, short, int -- code = (int)f
• long -- code = (int)(f ^ (f >>>32))
• float -- code = Float.floatToIntBits(f);
• double -- long l = Double.doubleToLongBits(f); code = (int)(l ^ (l >>> 32))
• all Objects, (where equals( ) calls equals( ) for this field) -- code = f.hashCode( )
• Array -- Apply above rules to each element

Combining the hash code(s) computed above: result = 37 * result + code;

Overrides:

hashCode in class Object

Returns:

(int) ( result >>> 32 ) ^ (int) result;

Object.hashCode()

intersection

public static final RasterRect intersection(RasterRect first,
                                            RasterRect second)

Create an intersection of the given RasterRects, if the given rasterects do not intersect, null will be returned.

Parameters:

first -

second -

Returns:

the intersection or null if the given rectangles do not intersect.
