setCx1

public void setCx1(float newCx1)

cy1

public float cy1()

setCy1

public void setCy1(float newCy1)

cx2

public float cx2()

setCx2

public void setCx2(float newCx2)

cy2

public float cy2()

setCy2

x

public float x()

Specified by:

x in interface Vertex2DINF

Returns:

x-coordinate as a float

setX

public void setX(float newX)

y

public float y()

Specified by:

y in interface Vertex2DINF

Returns:

y-coordinate as a float

setY

public void setY(float newY)

segmentType

public int segmentType()

Specified by:

segmentType in interface Vertex2DINF

Returns:

type of segment, either BezShape.LINE_SEGMENT or BezShape.CURVE_SEGMENT

coords

public float[] coords()

Specified by:

coords in interface Vertex2DINF

Returns:

coordinates as an array of float

clone

public BezVertex clone()

Specified by:

clone in interface Vertex2DINF

Overrides:

clone in class Object

Returns:

a deep copy of a Vertex2DINF

draw

public void draw(PApplet parent)

Description copied from interface: Vertex2DINF

Draws a path to the display. It is only valid to call this within a Processing beginShape/endShape pair where an initial vertex has been set with a call to vertex().

Specified by:

draw in interface Vertex2DINF

Parameters:

parent - the PApplet that handles drawing

draw

public void draw(PGraphics pg)

Description copied from interface: Vertex2DINF

Draws a path to an offscreen buffer. It is only valid to call this within a Processing beginShape/endShape pair where an initial vertex has been set with a call to vertex().

Specified by:

draw in interface Vertex2DINF

Parameters:

pg - a PGraphics instance

write

public void write(PrintWriter output)

Description copied from interface: Vertex2DINF

Writes a path segment to file. Multiple calls to this method should be bracketed by AIFileWriter.psMoveTo and AIFileWriter.paintPath commands

Specified by:

write in interface Vertex2DINF

Parameters:

output - a PrintWriter for output to file
