Detailed Description

Connects to vertices.

The edge class stores the ids of two seperate vertices indictating that they are connected (id1,id2). Unlike a pair the vertex with the lower value is always placed in id1, this allows us to reduce ambiguity when dealing with a link.

Constructor & Destructor Documentation

Edge() [1/2]

votca::tools::Edge::Edge ( )

default

~Edge()

virtual votca::tools::Edge::~Edge ( )

virtualdefault

Edge() [2/2]

votca::tools::Edge::Edge	(	Index	ID1,
		Index	ID2
	)

Creates an edge the smallest integer value will be placed in the id1 spot and the larger in the id2 spot

Member Function Documentation

contains()

bool votca::tools::Edge::contains

(

Index

ID

)

const

Determine if the edge contains the Index ID.

Definition at line 45 of file edge.cc.

getEndPoint1()

Index votca::tools::Edge::getEndPoint1 ( ) const

inline

grab the smaller integer

Definition at line 55 of file edge.h.

getEndPoint2()

Index votca::tools::Edge::getEndPoint2 ( ) const

inline

grab the larger integer

Definition at line 57 of file edge.h.

getOtherEndPoint()

Index votca::tools::Edge::getOtherEndPoint

(

Index

ver

)

const

Given one of the integers in the edge the other will be output.

Definition at line 37 of file edge.cc.

loop()

bool votca::tools::Edge::loop ( ) const

inline

Checks to see if an edge loops back on itself.

If both ends of the edge point to the same vertex than it is considered a loop.

Definition at line 65 of file edge.h.

operator!=()

bool votca::tools::Edge::operator!= ( const Edge &  ed ) const

virtual

Checks if Edges are not equivalent.

Reimplemented in votca::tools::ReducedEdge.

Definition at line 61 of file edge.cc.

operator<()

bool votca::tools::Edge::operator< ( const Edge &  ed ) const

virtual

If the vertices are smaller in value Edge ed1(2,3); Edge ed2(1,5); Edge ed3(4,1); priority is given to the smallest vertex assert(ed2<ed1); // will return true assert(ed3<ed1); // will return true assert(ed3<ed1); // will return true

Reimplemented in votca::tools::ReducedEdge.

Definition at line 63 of file edge.cc.

operator<=()

bool votca::tools::Edge::operator<= ( const Edge &  ed ) const

virtual

Reimplemented in votca::tools::ReducedEdge.

Definition at line 76 of file edge.cc.

operator==()

bool votca::tools::Edge::operator== ( const Edge &  ed ) const

virtual

Checks if Edges are equivalent.
