CSet:new

The new method creates an instance of the CSet class. Note that the object can also be created using new_set.

Note: This method's name uses all lower case to present it as the analog of the C++ new operator. Generally, the names of class methods begin with an uppercase letter but new and delete are different.

Syntax

S = CSet:new()

Default constructor. The new CSet S has no elements.

S = CSet:new( CSet_old )

This is a copy constructor. The new CSet S is initialized to the members of the CSet_old argument.

Example

The following example shows the use of a default constructor and destructor pair:

S = CSet:new()	-- create a new instance of S of the CSet class.
...	-- other uses of the class go here, between new and delete.
S:delete()	-- deletes the object and its associated memory.

The next example shows the use of both types of constructors:

S = CSet:new()	-- initialization constructor
S:Append( "Add" )	-- add a member
S:Append( "Mul" )	-- add a member
S:Append( "Div" )	-- add a member
Printf("Count= %d", S:Count())	-- result: Count = 3
S2 = CSet:new(S)	-- copy constructor
Printf("Count= %d", S2:Count())	-- result: Count = 3
