Detailed Description

A base class which provides memory management and object aggregation.

Introspection did not find any typical Config paths.

The memory management scheme is based on reference-counting with dispose-like functionality to break the reference cycles. The reference count is incremented and decremented with the methods Ref() and Unref(). If a reference cycle is present, the user is responsible for breaking it by calling Dispose() in a single location. This will eventually trigger the invocation of DoDispose() on itself and all its aggregates. The DoDispose() method is always automatically invoked from the Unref() method before destroying the Object, even if the user did not call Dispose() directly.


No Attributes are defined for this type.
No TraceSources are defined for this type.
Group: Core

Size of this type is 56 bytes (on a 64-bit architecture).

◆ Object() [1/2]

ns3::Object::Object ( )

Constructor.

Definition at line 96 of file object.cc.

References ns3::Object::Aggregates::buffer, m_aggregates, ns3::Object::Aggregates::n, and NS_LOG_FUNCTION.

◆ ~Object()

ns3::Object::~Object ( )
override

◆ Object() [2/2]

ns3::Object::Object ( const Object & o)
protected

Copy an Object.

Parameters
[in]othe Object to copy.

Allow subclasses to implement a copy constructor.

While it is technically possible to implement a copy constructor in a subclass, we strongly discourage you from doing so. If you really want to do it anyway, you have to understand that this copy constructor will not copy aggregated Objects, i.e, if your Object instance is already aggregated to another Object and if you invoke this copy constructor, the new Object instance will be a pristine standalone Object instance not aggregated to any other Object. It is thus your responsibility as a caller of this method to do what needs to be done (if it is needed) to ensure that the Object stays in a valid state.

Member Function Documentation

◆ AggregateObject()

void ns3::Object::AggregateObject ( Ptr< Object > other)

Aggregate two Objects together.

Parameters
[in]otherThe other Object pointer

This method aggregates the two Objects together: after this method returns, it becomes possible to call GetObject() on one to get the other, and vice-versa.

This method calls the virtual method NotifyNewAggregates() to notify all aggregated Objects that they have been aggregated together.

Returns
true if the reference count is non zero.

◆ CheckLoose()

bool ns3::Object::CheckLoose ( ) const
private

Check if any aggregated Objects have non-zero reference counts.

Returns
true if any of our aggregates have non zero reference count.

In some cases, when an event is scheduled against a subclass of Object, and if no one owns a reference directly to this Object, the Object is alive, has a refcount of zero and the method run when the event expires runs against the raw pointer, which means that we are manipulating an Object with a refcount of zero. So, instead we check the aggregate reference count.

void ns3::Object::Construct ( const AttributeConstructionList & attributes)
private

Initialize all member variables registered as Attributes of this TypeId.

Parameters
[in]attributesThe attribute values used to initialize the member variables of this Object's instance.

Invoked from ns3::ObjectFactory::Create and ns3::CreateObject only. Initialize all the member variables which were registered with the associated TypeId.

+ Here is the call graph for this function:

◆ Dispose()

void ns3::Object::Dispose ( )

Dispose of this Object.

Run the DoDispose() methods of this Object and all the Objects aggregated to it. After calling this method, this Object is expected to be totally unusable except for the Ref() and Unref() methods.

Note
You can call Dispose() many times on the same Object or different Objects aggregated together, and DoDispose() will be called only once for each aggregated Object.

This method is typically used to break reference cycles.

Note: the code here is a bit tricky because we need to protect ourselves from modifications in the aggregate array while DoDispose is called. The user's DoDispose implementation could call GetObject (which could reorder the array) and it could call AggregateObject which would add an object at the end of the array. So, to be safe, we restart the iteration over the array whenever we call some user code.

Attempt to delete this Object.

This method iterates over all aggregated Objects to check if they all have a zero refcount. If yes, the Object and all its aggregates are deleted. If not, nothing is done.

◆ DoDispose()

void ns3::Object::DoDispose ( )
protectedvirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.

Subclasses are expected to override this method and chain up to their parent's implementation once they are done. It is safe to call GetObject() and AggregateObject() from within this method.

◆ Initialize()

void ns3::Object::Initialize ( )

Invoke DoInitialize on all Objects aggregated to this one.

This method calls the virtual DoInitialize() method on all the Objects aggregated to this Object. DoInitialize() will be called only once over the lifetime of an Object, just like DoDispose() is called only once.

See also
DoInitialize()

Note: the code here is a bit tricky because we need to protect ourselves from modifications in the aggregate array while DoInitialize is called. The user's implementation of the DoInitialize method could call GetObject (which could reorder the array) and it could call AggregateObject which would add an object at the end of the array. To be safe, we restart iteration over the array whenever we call some user code, just in case.

Notify all Objects aggregated to this one of a new Object being aggregated.

This method is invoked whenever two sets of Objects are aggregated together. It is invoked exactly once for each Object in both sets.

[in]tidThe TypeId value to set.

Invoked from ns3::CreateObject only. Initialize the m_tid member variable to keep track of the type of this Object instance.

◆ UnidirectionalAggregateObject()

void ns3::Object::UnidirectionalAggregateObject ( Ptr< Object > other)

Aggregate an Object to another Object.

Parameters
[in]otherThe other Object pointer

This method aggregates the an object to another Object: after this method returns, it becomes possible to call GetObject() on the aggregating Object to get the other, but not vice-versa.

This method calls the virtual method NotifyNewAggregates() to notify all aggregated Objects that they have been aggregated together.

This method is useful only if there is the need to aggregate an object to more than one object at the same time, and should be avoided if not strictly necessary. In particular, objects aggregated with this method should be destroyed only after making sure that the objects they are aggregated to are destroyed as well. However, the destruction of the aggregating objects will take care of the unidirectional aggregated objects gracefully.

Beware that an object aggregated to another with this function behaves differently than other aggregates in the following ways. Suppose that Object B is aggregated unidirectionally:

  • It can be aggregated unidirectionally to more than one objects (e.g., A1 and A2).
  • It is not possible to call GetObject on B to find an aggregate of object A1 or A2.
  • When A1 or A2 are initialized, B is initialized, whichever happens first.
  • When A1 or A2 are destroyed, B is destroyed, whichever happens last.
  • If B is initialized, A1 and A2 are unaffected.
  • If B is forcefully destroyed, A1 and A2 are unaffected.

A pointer to an array of 'aggregates'.

A pointer to each Object aggregated to this Object is stored in this array. The array is shared by all aggregated Objects so the size of the array is indirectly a reference count.
