Ptr< T > ns3::Create ( Ts &&... args )

Create class instances by constructors with varying numbers of arguments and return them by Ptr.

This template work for any class T derived from ns3::SimpleRefCount

See also: CreateObject for methods to create derivatives of ns3::Object

Template Parameters

T	[explicit] The type of class object to create.
Ts	[deduced] Types of the constructor arguments.

Parameters

[in] args Constructor arguments.

Returns: A Ptr to the newly created T.
