Connected_parts
network-functions connected_parts
syntax
- connected_parts(F1, F2)
definition
The connected_parts function is used to find out how many connected (sub)networks exist in a set of links
connected_parts(F1, F2) results in a new domain-unit with a as subitem the attribute: Partnr.
The arguments F1 and F2 are the relations towards the the first and last node of a link set.
The Partnr item contains the relation towards the connected network(s).
Each value indicates a group of connected nodes. If all Partnr values are zero, the network is fully connected.
applies to
data items F1 and F2 with uint32 value-type
conditions
The domain units of arguments F1 and F2 must match.
example
unit<uint32> connected_parts := connected_parts(F1, F2);
