Methods
-
add(
EdgeEnd e) → void - Add the edge to the list of edges at this node
-
computeIM(
IntersectionMatrix im) → void -
Basic nodes do not compute IMs
override
-
computeMergedLocation(
Label label2, int eltIndex) → int - The location for a given eltIndex for a node will be one of { null, INTERIOR, BOUNDARY }. A node may be on both the boundary and the interior of a geometry; in this case, the rule is that the node is considered to be in the boundary. The merged location is the maximum of the two input values.
-
getCoordinate(
) → Coordinate -
@return a coordinate in this component (or null, if there are none)
override
-
getEdges(
) → EdgeEndStar? -
getLabel(
) → Label? -
inherited
-
isCovered(
) → bool -
inherited
-
isCoveredSet(
) → bool -
inherited
-
isIncidentEdgeInResult(
) → bool - Tests whether any incident edge is flagged as being in the result. This test can be used to determine if the node is in the result, since if any incident edge is in the result, the node must be in the result as well.
-
isInResult(
) → bool -
inherited
-
isIsolated(
) → bool -
An isolated component is one that does not intersect or touch any other
component. This is the case if the label has valid locations for
only a single Geometry.
override
-
isVisited(
) → bool -
inherited
-
mergeLabel(
Label label2) → void - To merge labels for two nodes, the merged location for each LabelElement is computed. The location for the corresponding node LabelElement is set to the result, as long as the location is non-null.
-
mergeLabelFromNode(
Node n) → void -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
setCovered(
bool isCovered) → void -
inherited
-
setInResult(
bool isInResult) → void -
inherited
-
setLabel(
Label label) → void -
inherited
-
setLabelBoundary(
int argIndex) → void - Updates the label of a node to BOUNDARY, obeying the mod-2 boundaryDetermination rule.
-
setLabelWithIndex(
int argIndex, int onLocation) → void -
setVisited(
bool isVisited) → void -
inherited
-
toString(
) → String -
A string representation of this object.
inherited
-
updateIM(
IntersectionMatrix im) → void -
Update the IM with the contribution for this component.
A component only contributes if it has a labelling for both parent geometries
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
