CCentroid:Class Description CCentroid:delete

CCentroid:new


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

Syntax

C = CCentroid:new()

  • Creates a default CCentroid with properties 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
