Field Detail

location

private final S2Point location

Vertex location.

incoming

private Edge incoming

Incoming edge.

outgoing

private Edge outgoing

Outgoing edge.

circles

private final java.util.List<Circle> circles

Circles bound with this vertex.

Constructor Detail

Vertex

Vertex(S2Point location)

Build a non-processed vertex not owned by any node yet.

Parameters:

location - vertex location

Method Detail

getLocation

public S2Point getLocation()

Get Vertex location.

Returns:

vertex location

bindWith

void bindWith(Circle circle)

Bind a circle considered to contain this vertex.

Parameters:

circle - circle to bind with this vertex

sharedCircleWith

Circle sharedCircleWith(Vertex vertex)

Get the common circle bound with both the instance and another vertex, if any.

When two vertices are both bound to the same circle, this means they are already handled by node associated with this circle, so there is no need to create a cut hyperplane for them.

Parameters:

vertex - other vertex to check instance against

Returns:

circle bound with both the instance and another vertex, or null if the two vertices do not share a circle yet

setIncoming

void setIncoming(Edge incoming)

Set incoming edge.

The circle supporting the incoming edge is automatically bound with the instance.

Parameters:

incoming - incoming edge

getIncoming

public Edge getIncoming()

Get incoming edge.

Returns:

incoming edge

setOutgoing

void setOutgoing(Edge outgoing)

Set outgoing edge.

The circle supporting the outgoing edge is automatically bound with the instance.

Parameters:

outgoing - outgoing edge

getOutgoing

public Edge getOutgoing()

Get outgoing edge.

Returns:

outgoing edge
