public NodeWithNumberedEdges()

Method Details

getSuccNumbers

public @Nullable IntSet getSuccNumbers()

Specified by:

getSuccNumbers in interface INodeWithNumberedEdges

Returns:

set of node numbers which are successors of this node

getPredNumbers

public @Nullable IntSet getPredNumbers()

Specified by:

getPredNumbers in interface INodeWithNumberedEdges

Returns:

set of node numbers which are predecessors of this node

addSucc

public void addSucc(int eqNumber)

Note that this variable appears on the RHS of an equation.

Specified by:

addSucc in interface INodeWithNumberedEdges

Parameters:

eqNumber - the equation number

addPred

public void addPred(int eqNumber)

Note that this variable appears on the LHS of an equation.

Specified by:

addPred in interface INodeWithNumberedEdges

Parameters:

eqNumber - the equation number

deleteSucc

public void removeIncomingEdges()
                         throws UnimplementedError

Description copied from interface: INodeWithNumberedEdges

remove all incoming edges to this this node. This must fix up the other nodes involved in each edge removed.

Specified by:

removeIncomingEdges in interface INodeWithNumberedEdges

Throws:

UnimplementedError

removeOutgoingEdges

public void removeOutgoingEdges()
                         throws UnimplementedError

Description copied from interface: INodeWithNumberedEdges

remove all outgoing edges to this this node. This must fix up the other nodes involved in each edge removed.

Specified by:

removeOutgoingEdges in interface INodeWithNumberedEdges

Throws:

UnimplementedError
