Detailed Description

implement the ns-3 type and attribute system

Every class which wants to integrate in the ns-3 type and attribute system should derive from this base class. This base class provides:

a way to associate an ns3::TypeId to each object instance
a way to set and get the attributes registered in the ns3::TypeId.

Member Function Documentation

void ns3::ObjectBase::ConstructSelf ( const AttributeConstructionList & attributes )

protected

Parameters

attributes the attribute values used to initialize the member variables of this object's instance.

Invoked from subclasses to initialize all of their attribute members. This method will typically be invoked automatically from ns3::CreateObject if your class derives from ns3::Object. If you derive from ns3::ObjectBase directly, you should make sure that you invoke this method from your most-derived constructor.

Parameters

name	the name of the attribute to read
value	a reference to the value where the result should be stored.

Returns: the attribute read.

If the input attribute name does not exist, this method crashes.

pure virtual

Returns: the TypeId associated to the most-derived type of this instance.

This method is typically implemented by ns3::Object::GetInstanceTypeId but some classes which derive from ns3::ObjectBase directly have to implement it themselves.

void ns3::ObjectBase::NotifyConstructionCompleted ( void )

protectedvirtual

This method is invoked once all member attributes have been initialized. Subclasses can override this method to be notified of this event but if they do this, they must chain up to their parent's NotifyConstructionCompleted method.

Reimplemented in ns3::FlowMonitor, and ns3::VisualSimulatorImpl.

Parameters

name	the name of the attribute to set
value	the name of the attribute to set

Set a single attribute. This cannot fail: if the input is invalid, it will crash immediately.
