Modifier and Type | Method and Description |
---|---|
void |
add(EdgeEnd e)
Add the edge to the list of edges at this node
|
protected void |
computeIM(IntersectionMatrix im)
Basic nodes do not compute IMs
|
Coordinate |
getCoordinate() |

getEdges() |
boolean |
isIncidentEdgeInResult()
Tests whether any incident edge is flagged as
being in the result.
|
boolean |
isIsolated()
An isolated component is one that does not intersect or touch any other
component.
|
void |
mergeLabel(Label label2)
To merge labels for two nodes,
the merged location for each LabelElement is computed.
|
void |
mergeLabel(Node n) |
void |
print(PrintStream out) |
void |
setLabel(int argIndex,
int onLocation) |
void |
setLabelBoundary(int argIndex)
Updates the label of a node to BOUNDARY,
obeying the mod-2 boundaryDetermination rule.
