Method Detail

getLatitudeDeg

double getLatitudeDeg()

Gets the latitude of the node position in degree.

Returns:

the latitude of the node position in degree

getLongitudeDeg

double getLongitudeDeg()

Gets the longitude of the node position in degree.

Returns:

the longitude of the node position in degree

getGeoCoordinates

GeoCoordinates getGeoCoordinates()

Gets the geo coordinates of the node position.

Returns:

the geo coordinates of the node position

getConnectedLines

Iterator<Line> getConnectedLines()

Returns a set of connected lines. Connected lines are lines whose end node or start node are equal to this node.

Returns:

a set if incident lines

getNumberConnectedLines

int getNumberConnectedLines()

Gets the number of connected lines.

Returns:

the number of connected lines

getOutgoingLines

Iterator<Line> getOutgoingLines()

Returns a set of outgoing lines. Outgoing lines are lines whose start nodes are equal to this node.

Returns:

a set of outgoing lines

getIncomingLines

Iterator<Line> getIncomingLines()

Returns a set of incoming lines. Incoming lines are lines whose end nodes are equal to this node.

Returns:

a set of incoming lines

equals

boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

Overrides:

equals in class Object

Parameters:

obj - the reference object with which to compare

Returns:

true, if this object is the same as the obj argument, otherwise false

hashCode

int hashCode()

Returns a hash code value for the line.

Overrides:

hashCode in class Object

Returns:

a hash code value for the line

getID

long getID()

Return the unique ID of the node

Returns:

the unique ID
