◆ Create()

template<typename T , typename... Ts>

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.

◆ operator!=() [1/3]

template<typename T1 , typename T2 >

bool ns3::operator!=	(	Ptr< T1 > const &	lhs,
		T2 const *	rhs

T2	[deduced] Type of the object on the rhs.

Parameters

[in]	lhs	The left operand.
[in]	rhs	The right operand.

Returns: true if the operands point to the same underlying object.
