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()

bullet.gif    Default constructor. The new CSet S has no elements.

S = CSet:new( CSet_old )

bullet.gif    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
