Functions | |
template<class PGraph > | |
PGraph | TSnap::ToGraph (PTable Table, const TStr &SrcCol, const TStr &DstCol, TAttrAggr AggrPolicy) |
Sequentially converts the table into a graph with links from nodes in SrcCol to those in DstCol . More... | |
template<class PGraph > | |
PGraph | TSnap::ToNetwork (PTable Table, const TStr &SrcCol, const TStr &DstCol, TStrV &SrcAttrV, TStrV &DstAttrV, TStrV &EdgeAttrV, TAttrAggr AggrPolicy) |
Converts the Table into a graph with edges from SrcCol to DstCol , and attribute vector defined by the arguments. More... | |
template<class PGraph > | |
PGraph | TSnap::ToNetwork (PTable Table, const TStr &SrcCol, const TStr &DstCol, TAttrAggr AggrPolicy) |
Calls ToNetwork with an empty attribute vector. Convenience wrapper. More... | |
template<class PGraph > | |
PGraph | TSnap::ToNetwork (PTable Table, const TStr &SrcCol, const TStr &DstCol, TStrV &EdgeAttrV, TAttrAggr AggrPolicy) |
Converts table to a network sequentially. Use if network has only edge attributes. More... | |
template<class PGraph > | |
PGraph | TSnap::ToNetwork (PTable Table, const TStr &SrcCol, const TStr &DstCol, TStrV &EdgeAttrV, PTable NodeTable, const TStr &NodeCol, TStrV &NodeAttrV, TAttrAggr AggrPolicy) |
Converts table to network sequentially. Takes edges from Table and nodes explicitly from NodeCol in NodeTable , with attribute vectors passed as columns in corresponding tables. More... | |
int | TSnap::LoadCrossNet (TCrossNet &Graph, PTable Table, const TStr &SrcCol, const TStr &DstCol, TStrV &EdgeAttrV) |
Loads the edges from the TTable and EdgeAttrV specifies columns containing edge attributes. More... | |
int | TSnap::LoadMode (TModeNet &Graph, PTable Table, const TStr &NCol, TStrV &NodeAttrV) |
Loads the nodes specified in column NCol from the TTable with the attributes specified in NodeAttrV. More... | |
template<class PGraphMP > | |
PGraphMP | TSnap::ToGraphMP (PTable Table, const TStr &SrcCol, const TStr &DstCol) |
Performs table to graph conversion in parallel using the sort-first algorithm. This is the recommended method to use. More... | |
template<class PGraphMP > | |
PGraphMP | TSnap::ToGraphMP3 (PTable Table, const TStr &SrcCol, const TStr &DstCol) |
Performs table to graph conversion in parallel. Uses the hash-first method, which is less optimal, use ToGraphMP instead. More... | |
template<class PGraphMP > | |
PGraphMP | TSnap::ToNetworkMP (PTable Table, const TStr &SrcCol, const TStr &DstCol, TStrV &SrcAttrV, TStrV &DstAttrV, TStrV &EdgeAttrV, TAttrAggr AggrPolicy) |
Does Table to Network conversion in parallel using the sort-first algorithm. This is the recommended method to use. More... | |
template<class PGraphMP > | |
PGraphMP | TSnap::ToNetworkMP2 (PTable Table, const TStr &SrcCol, const TStr &DstCol, TStrV &SrcAttrV, TStrV &DstAttrV, TStrV &EdgeAttrV, TAttrAggr AggrPolicy) |
Implements table to network conversion in parallel. Not the recommended algorithm, using ToNetworkMP instead. More... | |
template<class PGraphMP > | |
PGraphMP | TSnap::ToNetworkMP (PTable Table, const TStr &SrcCol, const TStr &DstCol, TStrV &EdgeAttrV, TAttrAggr AggrPolicy) |
