Detailed Description

Stores a set of four Points that represent a Quadrangle region.

Constructor & Destructor Documentation

__construct()

__construct	(	Point	$leftTop,
		Point	$rightTop,
		Point	$rightBottom,
		Point	$leftBottom
	)

Initializes a new instance of the Quadrangle structure with the describing points.

Parameters

leftTop	A Point that represents the left-top corner of the Quadrangle.
rightTop	A Point that represents the right-top corner of the Quadrangle.
rightBottom	A Point that represents the right-bottom corner of the Quadrangle.
leftBottom	A Point that represents the left-bottom corner of the Quadrangle.

Member Function Documentation

contains()

contains

(

Point

$pt

)

Determines if the specified Point is contained within this Quadrangle structure.

Parameters

pt	The Point to test.

Returns

Returns true if Point is contained within this Quadrangle structure; otherwise, false.

containsPoint()

containsPoint	(		$x,
			$y
	)

Determines if the specified point is contained within this Quadrangle structure.

Parameters

x	The x point cordinate.
y	The y point cordinate.

Returns

Returns true if point is contained within this Quadrangle structure; otherwise, false.

containsQuadrangle()

containsQuadrangle

(

Quadrangle

$quad

)

Determines if the specified Quadrangle is contained or intersect this Quadrangle structure.

Parameters

quad	The Quadrangle to test.

Returns

containsRectangle()

containsRectangle

(

Rectangle

$rect

)

Determines if the specified Rectangle is contained or intersect this Quadrangle structure.

Parameters

rect	The Rectangle to test.

Returns

Returns true if Rectangle is contained or intersect this Quadrangle structure; otherwise, false.

EMPTY()

static EMPTY ( )

static

Represents a Quadrangle structure with its properties left uninitialized.Value: Quadrangle

equals()

equals

(

Quadrangle

$other

)

Returns a value indicating whether this instance is equal to a specified Quadrangle value.

Parameters

$other

An Quadrangle value to compare to this instance.

Returns

true if obj has the same value as this instance; otherwise, false.
