Detailed Description

Provides the physical topology of the power system. It gets read from a file. There is documentation on the wiki.

It's really important that we have this long documentation, even though there is nothing to say that would actually be helpful: look at the only (public) function in this class.

Constructor & Destructor Documentation

freedm::broker::CPhysicalTopology::CPhysicalTopology ( )

private

CPhysicalTopology::CPhysicalTopology

Description:

Private constructor for the singleton instance

Precondition:

None

Postcondition:

LoadTopology has been called.

Member Function Documentation

CPhysicalTopology & freedm::broker::CPhysicalTopology::Instance ( )

static

CPhysicalTopology::Instance

Description:

Get the singleton instance of this class

bool freedm::broker::CPhysicalTopology::IsAvailable

(

)

CPhysicalTopology::IsAvailable

Description:

Indicates whether or not a physical topology is available

Precondition:

None

Postcondition:

None

Returns

True if a physical topology has been successfully loaded.

void freedm::broker::CPhysicalTopology::LoadTopology ( )

private

CPhysicalTopology::LoadTopology

Description:

Load the topology from a file

Precondition:

The topology is correctly specified in a topology config file. The CGlobalConfiguration class has an entry loaded with a working path to the topology file.

Postcondition:

The topology is loaded into the related maps: the adjacency list is loaded into m_adjlist, and the map of which edges FIDs control is loaded into m_fidcontrol.

Returns

None

CPhysicalTopology::VertexSet freedm::broker::CPhysicalTopology::ReachablePeers	(	std::string	source,
		CPhysicalTopology::FIDState	fidstate
	)

Description:

Find the reachable peers. Performs a BFS on the physical topology starting at a source vertex. Nodes with FID are checked for the status of their FID. If the FID status is unavailable or the FID is open, the edge is considered Broken

Precondition:

A physical topology has been loaded.

Postcondition:

No change to class state.

Returns

A set of UUIDs of hostnames that are still reachable.

Parameters

source	The initial vertex to perform BFS from.
fidstate	a map that is FID Name -> State. A closed FID is true, an open FID is false. If an FID is open edges it controls are not used.

std::string freedm::broker::CPhysicalTopology::RealNameFromVirtual ( std::string  vname )

private

CPhysicalTopology::RealNameFromVirtual

Description:

Translates a virtual edge name to a real one.

Precondition:

The m_strans member property has been populated (happens as part of the topology loading process)

Postcondition:

Returns the real name of the node in the physical topology.

Returns

The real name of the node in the physical topology. If the node is named by an SST entry, it gives that name. Otherwise it is the virtual name prepended by the VNAME_PREFIX.

Parameters

vname

the virtual name to look up.
