CCentroid:new

CCentroid:new

The new method constructs a new instance of a CCentroid object. The CCentroid class includes data members that control calculation of centroid positions. Two different constructor overloads are available to create a new CCentroid and initialize the data members.

Syntax

C = CCentroid:new()

Creates a default CCentroid with data members initialized to default values.

C = CCentroid:new( CCentroid2 )

This is a copy constructor. It creates a new CCentroid C initialized to the members of the CCentroid2 argument.

Remarks

Two overloads are provided for the CCentroid class. They create a default CCentroid and a copy of a CCentroid. If you pass something other than nil or another CCentroid—such as a string—then the default constructor is used.

Example

The following script fragment illustrates using the 2 constructors. All produce the same result:

C1 = CCentroid:new()	-- create CCentroid C1 and set values
C1:SetSign(false)	-- change the default sign
C2 = CCentroid:new( C1 )	-- copy C1 to a new CCentroid C2
Printf("C1 sign = %d", C1:GetSign() )	-- result: C1 sign = 0
Printf("C2 sign = %d", C2:GetSign() )	-- result: C2 sign = 0
