Public Member Functions
	mxGeometry ()
	Constructs a new geometry at (0, 0) with the width and height set to 0.
	mxGeometry (double x, double y, double width, double height)
	Constructs a geometry using the given parameters.
	mxGeometry (mxGeometry geometry)
	Constructs a copy of the given geometry.
mxPoint	GetTerminalPoint (bool source)
	Returns the point representing the source or target point of this edge. This is only used if the edge has no source or target vertex.
mxPoint	SetTerminalPoint (mxPoint point, bool source)
	Sets the sourcePoint or targetPoint to the given point and returns the new point.
void	Translate (double dx, double dy)
	Translates the geometry by the specified amount. That is, x and y of the geometry, the sourcePoint, targetPoint and all elements of points are translated by the given amount. X and y are only translated if the geometry is not relative. If TRANSLATE_CONTROL_POINTS is false, then are not modified by this function.
new mxGeometry	Clone ()
	Returns a new instance of the same geometry.
Static Public Attributes
static bool	TRANSLATE_CONTROL_POINTS = true
	Global switch to translate the points in translate. Default is true.
Protected Attributes
mxRectangle	alternateBounds
	Stores alternate values for x, y, width and height in a rectangle. Default is null.
mxPoint	sourcePoint
	Defines the source-point of the edge. This is used if the corresponding edge does not have a source vertex. Otherwise it is ignored. Default is null.
mxPoint	targetPoint
	Defines the target-point of the edge. This is used if the corresponding edge does not have a source vertex. Otherwise it is ignored. Default is null.
mxPoint	offset
	Holds the offset of the label for edges. This is the absolute vector between the center of the edge and the top, left point of the label. Default is null.
List< mxPoint >	points
	List of mxPoints which specifies the control points along the edge. These points are the intermediate points on the edge, for the endpoints use targetPoint and sourcePoint or set the terminals of the edge to a non-null value. Default is null.
bool	relative = false
	Specifies if the coordinates in the geometry are to be interpreted as relative coordinates. Default is false. This is used to mark a geometry with an x- and y-coordinate that is used to describe an edge label position.
Properties
mxRectangle	AlternateBounds `[get, set]`
	Sets or returns the alternate bounds.
mxPoint	SourcePoint `[get, set]`
	Sets or returns the source point.
mxPoint	TargetPoint `[get, set]`
	Sets or returns the target point.
List< mxPoint >	Points `[get, set]`
	Sets or returns the list of control points.
mxPoint	Offset `[get, set]`
	Sets or returns the offset.
bool	Relative `[get, set]`
	Sets or returns if the geometry is relative.

Detailed Description

Represents the geometry of a cell. For vertices, the geometry consists of the x- and y-location, as well as the width and height. For edges, the edge either defines the source- and target-terminal, or the geometry defines the respective terminal points.

Constructor & Destructor Documentation

com.mxgraph.mxGeometry.mxGeometry ( ) [inline]

com.mxgraph.mxGeometry.mxGeometry	(	double	x,
		double	y,
		double	width,
		double	height
	)		`[inline]`

Constructs a geometry using the given parameters.

Parameters:

x	X-coordinate of the new geometry.
y	Y-coordinate of the new geometry.
width	Width of the new geometry.
height	Height of the new geometry.

com.mxgraph.mxGeometry.mxGeometry ( mxGeometry geometry ) [inline]

Constructs a copy of the given geometry.

Parameters:

geometry Geometry to construct a copy of.

Member Function Documentation

new mxGeometry com.mxgraph.mxGeometry.Clone ( ) [inline]

Returns a new instance of the same geometry.

Returns:: Returns a clone of the geometry.

Reimplemented from com.mxgraph.mxRectangle.

mxPoint com.mxgraph.mxGeometry.GetTerminalPoint ( bool source ) [inline]

Returns the point representing the source or target point of this edge. This is only used if the edge has no source or target vertex.

Parameters:

source Boolean that specifies if the source or target point should be returned.

Returns:: Returns the source or target point.

mxPoint com.mxgraph.mxGeometry.SetTerminalPoint	(	mxPoint	point,
		bool	source
	)		`[inline]`

Sets the sourcePoint or targetPoint to the given point and returns the new point.

Parameters:

point	Point to be used as the new source or target point.
source	Boolean that specifies if the source or target point should be set.

Returns:: Returns the new point.

void com.mxgraph.mxGeometry.Translate	(	double	dx,
		double	dy
	)		`[inline]`

Translates the geometry by the specified amount. That is, x and y of the geometry, the sourcePoint, targetPoint and all elements of points are translated by the given amount. X and y are only translated if the geometry is not relative. If TRANSLATE_CONTROL_POINTS is false, then are not modified by this function.

Parameters:

dx	Integer that specifies the x-coordinate of the translation.
dy	Integer that specifies the y-coordinate of the translation.

Member Data Documentation

mxRectangle com.mxgraph.mxGeometry.alternateBounds [protected]

Stores alternate values for x, y, width and height in a rectangle. Default is null.

mxPoint com.mxgraph.mxGeometry.offset [protected]
