Member Function Documentation

◆ ConnectFailSafe()

bool ns3::Config::ConfigImpl::ConnectFailSafe	(	std::string	path,
		const CallbackBase &	cb
	)

Parameters

[in]	path	A path to match trace sources.
[in]	cb	The callback to connect to the matching trace sources.

This function will attempt to find all trace sources which match the input path and will then connect the input callback to them in such a way that the callback will receive an extra context string upon trace event notification.

Returns: true if any trace sources could be connected.

◆ ConnectWithoutContextFailSafe()

bool ns3::Config::ConfigImpl::ConnectWithoutContextFailSafe	(	std::string	path,
		const CallbackBase &	cb
	)

Parameters

[in]	path	A path to match trace sources.
[in]	cb	The callback to connect to the matching trace sources.

This function will attempt to find all trace sources which match the input path and will then connect the input callback to them. If no matching trace sources are found, this method will return false; otherwise true.

Returns: true if any trace sources could be connected.

[in]	cb	The callback to connect to the matching trace sources.

This function undoes the work of Config::ConnectWithContext.

Parameters

[in] path The path to perform a match against

Returns: A container which contains all the objects which match the input path.

	)		const

private

Break a Config path into the leading path and the last leaf token.

Parameters

[in]	path	The Config path.
[in,out]	root	The leading part of the path, up to the final slash.
[in,out]	leaf	The trailing part of the path.

◆ RegisterRootNamespaceObject()

void ns3::Config::ConfigImpl::RegisterRootNamespaceObject ( Ptr< Object > obj )

Parameters

[in] obj A new root object

Each root object is used during path matching as the root of the path by Config::Connect, and Config::Set.

◆ Set()

void ns3::Config::ConfigImpl::Set	(	std::string	path,
		const AttributeValue &	value
	)

Parameters

[in]	path	A path to match attributes.
[in]	value	The value to set in all matching attributes.

This function will attempt to find attributes which match the input path and will then set their value to the input value. If no such attributes are found, the function will throw a fatal error; use SetFailSafe if the lack of a match is to be permitted.

		const AttributeValue &	value
	)

Parameters

[in]	path	A path to match attributes.
[in]	value	The value to set in all matching attributes.

This function will attempt to find attributes which match the input path and will then set their value to the input value, and will return true if at least one such attribute is found.
