Curve

The ‘Curve’ class presents a data structure for representing a curve.

Summary

Curve	The ‘Curve’ class presents a data structure for representing a curve.
Variables
m_objStart	A point object for storing information about the start point of this curve.
m_objEnd	A point object for storing information about the end point of this curve.
m_objControl	A point object for storing information about the control point of this curve.
Functions and Properties
Curve	Constructor.
start	Gets the starting point of the curve.
end	Gets the end point of the curve.
control	Gets the control point of the curve.
draw	Uses the data stored by this object to draw a curve into the specified graphics object.
clone	Clones this object.
dispose	Performs any appropriate clean-up tasks for garbage collection such as removing event listeners, setting object references to ‘null’, etc.
init	Initializes this object.
