          com.sencha.gxt.chart.client.draw.path.CurveToQuadraticSmooth

public class CurveToQuadraticSmooth
extends EndPointCommand

A PathCommand that represents a shorthand quadratic Bézier segment. The control point is assumed to be the reflection of the control point on the previous command relative to the current point.

Constructor Summary

CurveToQuadraticSmooth()
Creates a shorthand quadratic curve PathCommand with the given points.

CurveToQuadraticSmooth(CurveToQuadraticSmooth smoothQuadratic)
Creates a copy of the given shorthand quadratic curve PathCommand with the given points.

CurveToQuadraticSmooth(double x, double y)
Creates a shorthand quadratic curve PathCommand with the given points.

CurveToQuadraticSmooth(double x, double y, boolean relative)
Creates a shorthand quadratic curve PathCommand with the given points.

Method Summary

CurveToQuadraticSmooth	copy() Returns a copy of the path command.
boolean	nearEqual(PathCommand command) Determines equality of two commands using rounded values.
CurveTo	toCurve(PrecisePoint currentPoint, PrecisePoint movePoint, PrecisePoint curvePoint, PrecisePoint quadraticPoint) Converts the PathCommand to a CurveTo command.

Constructor Detail

CurveToQuadraticSmooth

public CurveToQuadraticSmooth()

Creates a shorthand quadratic curve PathCommand with the given points. Defaults to absolute.

CurveToQuadraticSmooth

public CurveToQuadraticSmooth(CurveToQuadraticSmooth smoothQuadratic)

Creates a copy of the given shorthand quadratic curve PathCommand with the given points.

Parameters:

smoothQuadratic - the shorthand quadratic curve to copy

CurveToQuadraticSmooth

public CurveToQuadraticSmooth(double x,
                              double y)

Creates a shorthand quadratic curve PathCommand with the given points. Defaults to absolute.

Parameters:

x - the x-coordinate of the end of the segment

y - the y-coordinate of the end of the segment

CurveToQuadraticSmooth

public CurveToQuadraticSmooth(double x,
                              double y,
                              boolean relative)

Creates a shorthand quadratic curve PathCommand with the given points.

Parameters:

x - the x-coordinate of the end of the segment

y - the y-coordinate of the end of the segment

relative - true if the command is relative

Method Detail

copy

public CurveToQuadraticSmooth copy()

Description copied from class: PathCommand

Returns a copy of the path command.

Specified by:

copy in class PathCommand

Returns:

a copy of the path command

nearEqual

public boolean nearEqual(PathCommand command)

Description copied from class: PathCommand

Determines equality of two commands using rounded values.

Specified by:

nearEqual in class PathCommand

Parameters:

command - the command to compare

Returns:

true if equal and false otherwise

toCurve

public CurveTo toCurve(PrecisePoint currentPoint,
                       PrecisePoint movePoint,
                       PrecisePoint curvePoint,
                       PrecisePoint quadraticPoint)

Description copied from class: PathCommand

Converts the PathCommand to a CurveTo command. If a MoveTo no conversion takes place, but the current move point is updated.

Specified by:

toCurve in class PathCommand

Parameters:

currentPoint - the current point of the path

movePoint - the frame of reference for the path

curvePoint - the frame of reference for the Bézier

quadraticPoint - the beginning of the last quadratic curve

Returns:

the converted command

toString

public String toString()

Overrides:

toString in class Object
