Constructor Detail

Rectangle

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

Creates a new rectangle area with the designated coordinates of the top-left corner, and the designated extent.

Parameters:

x - The x-coordinate of the top-left corner of the rectangular area.

y - The y-coordinate of the top-left corner of the rectangular area

width - The width of the rectangular area.

height - The height of the rectangular area.

Rectangle

public Rectangle(int x,
                 int y,
                 boolean point)

Creates a new point having the designated coordinates or a relative rectangle with the designated extent.

Parameters:

x - The x-coordinate of the point or the width of the relative rectangular area.

y - The y-coordinate of the point or the height of the relative rectangular area.

point - Whether to create a point (having no extent) or a relative rectangular area.

Method Detail

getX

public int getX()

Gets the x-coordinate of the top-left corner of the rectangular area. In case of a relative rectangular area, the returned value is invalid.

Returns:

The x-coordinate of the top-left corner of the rectangular area. In case of a relative rectangular area, the returned value is invalid.

getY

public int getY()

Gets the y-coordinate of the top-left corner of the rectangular area. In case of a relative rectangular area, the returned value is invalid.

Returns:

The y-coordinate of the top-left corner of the rectangular area. In case of a relative rectangular area, the returned value is invalid.

getWidth

public int getWidth()

Gets the width of the rectangular area or 0 for a point.

Returns:

The width of the rectangular area or 0 for a point.

getHeight

public int getHeight()

Gets the height of the rectangular area or 0 for a point.

Returns:

The height of the rectangular area or 0 for a point.

isRelative

public boolean isRelative()

Gets whether the rectangular area is relative and therefore the coordinates are invalid.

Returns:

Whether the rectangular area is relative and therefore the coordinates are invalid.
