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 AttributeList &

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.

void ns3::ObjectBase::GetAttribute	(	std::string	name,
		AttributeValue &	value
	)			const

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.

bool ns3::ObjectBase::GetAttributeFailSafe	(	std::string	name,
		AttributeValue &	attribute
	)			const

Parameters:

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

Returns:

true if the requested attribute was found, false otherwise.

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

virtual TypeId ns3::ObjectBase::GetInstanceTypeId

(

void

)

const [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.

virtual void ns3::ObjectBase::NotifyConstructionCompleted

(

void

)

[protected, virtual]

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.

void ns3::ObjectBase::SetAttribute	(	std::string	name,
		const AttributeValue &	value
	)

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.

bool ns3::ObjectBase::SetAttributeFailSafe	(	std::string	name,
		const AttributeValue &	value
	)

Parameters:

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

Returns:

true if the requested attribute exists and could be set, false otherwise.

bool ns3::ObjectBase::TraceConnect	(	std::string	name,
		std::string	context,
		const CallbackBase &	cb
	)

Parameters:

	name	the name of the targetted trace source
	context	the trace context associated to the callback
	cb	the callback to connect to the trace source.

The targetted trace source should be registered with TypeId::AddTraceSource.

bool ns3::ObjectBase::TraceConnectWithoutContext	(	std::string	name,
		const CallbackBase &	cb
	)

Parameters:

	name	the name of the targetted trace source
	cb	the callback to connect to the trace source.

		const CallbackBase &	cb
	)

Parameters:

	name	the name of the targetted trace source
	context	the trace context associated to the callback
	cb	the callback to disconnect from the trace source.

The targetted trace source should be registered with TypeId::AddTraceSource.

bool ns3::ObjectBase::TraceDisconnectWithoutContext	(	std::string	name,
		const CallbackBase &	cb
	)

Parameters:

	name	the name of the targetted trace source
	cb	the callback to disconnect from the trace source.
