Detailed Description

Edge iterator for graph associated with a polymer.

Usage: Suppose that object p is an instance of a subclass of PolymerSpecies. The following snippet illustrates how to iterate from edge (or block) iSource to edge iTarget of the associated polymer:

EdgeIterator = iter(p);
int iEdge;
for (iter.begin(iSource, iTarget); iter.notEnd(); ++iter) {
   iEdge = iter.currentEdgeId();
   // do something with edge iEdge
}

◆ begin()

◆ operator++()

EdgeIterator & Pscf::EdgeIterator::operator++ ( )

Increment operator - move to next vertex.

References Pscf::PolymerSpecies::edge(), notEnd(), Pscf::PolymerSpecies::path(), UTIL_CHECK, and Pscf::Edge::vertexId().

◆ currentEdgeId()

int Pscf::EdgeIterator::currentEdgeId ( ) const

Get index of the current edge.

Referenced by Pscf::Rpc::IntraCorrelation< D >::computeIntraCorrelations(), and Pscf::Rpg::IntraCorrelation< D >::computeIntraCorrelations().

◆ currentVertexId()

int Pscf::EdgeIterator::currentVertexId ( ) const

Get index of the current vertex.

When the current edge is not the target edge, the current vertex is the vertex of the current edge that is closer to the closest vertex of the target edge.

When the current edge is also the target edge, the current vertex is the vertex of the target edge that is farther from the initial source edge.

Definition at line 126 of file EdgeIterator.cpp.

◆ isEnd()

bool Pscf::EdgeIterator::isEnd ( ) const

Return true iff currentId == targetId.

Definition at line 132 of file EdgeIterator.cpp.

◆ notEnd()

bool Pscf::EdgeIterator::notEnd ( ) const

Return true iff currentId != targetId.
