Add() [1/3]

void ns3::Names::Add ( Ptr< Object > context, std::string name, Ptr< Object > object )

static

A low-level form of Names::Add allowing you to specify the path to the parent object (under which you want this name to be defined) in the form of a previously named object.

In some use cases, it is desirable to break up the path in the names name space into a path and a name. This is analogous to a file system operation in which you provide a directory name and a file name. Recall that the path string actually refers to a previously named object, "under" which you want to accomplish some naming action.

However, the path is sometimes not available, and you only have the object that is represented by the path in the names name space. To support this use-case in a reasonably high-performance way, the path string is can be replaced by the object pointer to which that path would refer. In the spirit of the Config code where this use-case is most prominent, we refer to this object as the "context" for the names operation.

You can think of the context roughly as the inode number of a directory file in Unix. The inode number can be used to look up the directory file which contains the list of file names defined at that directory level. Similarly the context is used to look up an internal name service entry which contains the names defined for that context.

For example, consider a situation where you have previously named an object "/Names/server". If you further want to create an association for between a Ptr<Object> object that you want to live "under" the server in the name space – perhaps "eth0" – you could do this by providing a complete path to the new name: Names::Add ("/Names/server/eth0", object). If, however, somewhere in your code you only had a pointer to the server, say Ptr<Node> node, and not a handy path string, you could also accomplish this by Names::Add (node, "eth0", object).

Duplicate names are not allowed at the same level in a path. In the case of this method, the context object gives the same information as a path string. You may associate similar names with different paths. For example, if you define"/Names/Client", you may not define another "/Names/Client" just as you may not have two files with the same name in a classical filesystem. However, you may have "/Names/Client/eth0" and "/Names/Server/eth0" defined at the same time just as you might have different files of the same name under different directories.

Parameters

[in]	context	A smart pointer to an object that is used in place of the path under which you want this new name to be defined.
[in]	name	The name of the object you want to associate.
[in]	object	A smart pointer to the object itself.

Here is the call graph for this function:

Add() [2/3]

void ns3::Names::Add ( std::string name, Ptr< Object > object )

static

Add the association between the string "name" and the Ptr<Object> obj.

The name may begin either with "/Names" to explicitly call out the fact that the name provided is installed under the root of the name space, or it may begin with the name of the first object in the path. For example, Names::Add ("/Names/client", obj) and Names::Add ("client", obj) accomplish exactly the same thing. A name at a given level in the name space path must be unique. In the case of the example above, it would be illegal to try and associate a different object with the same name: "client" at the same level ("/Names") in the path.

As well as specifying a name at the root of the "/Names" namespace, the name parameter can contain a path that fully qualifies the name to be added. For example, if you previously have named an object "client" in the root namespace as above, you could name an object "under" that name by making a call like Names::Add ("/Names/client/eth0", obj). This will define the name "eth0" and make it reachable using the path specified. Note that Names::Add ("client/eth0", obj) would accomplish exactly the same thing.

Duplicate names are not allowed at the same level in a path, however you may associate similar names with different paths. For example, if you define "/Names/Client", you may not define another "/Names/Client" just as you may not have two files with the same name in a classical filesystem. However, you may have "/Names/Client/eth0" and "/Names/Server/eth0" defined at the same time just as you might have different files of the same name under different directories.

Parameters

[in]	name	The name of the object you want to associate; which may be prepended with a path to that object.
[in]	object	A smart pointer to the object itself.

Add() [3/3]

void ns3::Names::Add ( std::string path, std::string name, Ptr< Object > object )

static

An intermediate form of Names::Add allowing you to provide a path to the parent object (under which you want this name to be defined) in the form of a name path string.

In some cases, it is desirable to break up the path used to describe an item in the names namespace into a path and a name. This is analogous to a file system operation in which you provide a directory name and a file name.

For example, consider a situation where you have previously named an object "/Names/server".

Parameters

[in]	path	A path name describing a previously named object under which you want this new name to be defined.
[in]	name	The name of the object you want to associate.
[in]	object	A smart pointer to the object itself.

Find() [1/3]

template<typename T >

Ptr< T > ns3::Names::Find ( Ptr< Object > context, std::string name )

static

Given a path to an object and an object name, look through the names defined under the path to see if there's an object there with the given name.

In some cases, it is desirable to break up the path used to describe an item in the names namespace into a path and a name. This is analogous to a file system operation in which you provide a directory name and a file name.

For example, consider a situation where you have previously named an object "/Names/server/eth0". If you want to discover the object which you associated with this path, you could do this in two ways, depending on which was more convenient: Names::Find ("/Names/server/eth0") or, using the split path and name approach, Names::Find ("/Names/server", "eth0").

However, the path is sometimes not available, and you only have the object that is represented by the path in the names name space. To support this use-case in a reasonably high-performance way, the path string is can be replaced by the object pointer to which that path would refer.

Similarly the context is used to look up an internal name service entry which contains the names defined for that context.

Parameters

[in]	context	A smart pointer to an object that is used in place of the path under which you want this new name to be defined.
[in]	name	A string containing a name to search for.

Returns

A smart pointer to the named object converted to the requested type.

Here is the call graph for this function:

Find() [2/3]

template<typename T >

Ptr< T > ns3::Names::Find ( std::string path )

static

Given a name path string, look to see if there's an object in the system with that associated to it.

If there is, do a GetObject on the resulting object to convert it to the requested typename and return it.

An object can be referred to in two ways. Either you can talk about it using its fully qualified path name, for example, "/Names/client/eth0" or you can refer to it by its name, in this case "eth0".

This method requires that the name path of the object be provided, e.g., "Names/client/eth0".

Parameters

[in]

path

A string containing a name space path used to locate the object.

Returns

A smart pointer to the named object converted to the requested type.
