Method Detail

weigher

protected org.onosproject.net.topology.LinkWeigher weigher(List<org.onosproject.net.intent.Constraint> constraints)

Returns an edge-weight capable of evaluating links on the basis of the specified constraints.

Parameters:

constraints - path constraints

Returns:

edge-weight function

checkPath

protected boolean checkPath(org.onosproject.net.Path path,
                            List<org.onosproject.net.intent.Constraint> constraints)

Validates the specified path against the given constraints.

Parameters:

path - path to be checked

constraints - path constraints

Returns:

true if the path passes all constraints

Deprecated.

Computes a path between two ConnectPoints.

Parameters:

intent - intent on which behalf path is being computed

one - start of the path

two - end of the path

Returns:

Path between the two

Throws:

PathNotFoundException - if a path cannot be found
