Detailed Description

A Node is described by it's XY coordinates.

It is used to represent start and end points of curves, intersections... Several Curves can share the same Node. This is the 'Lazy' version of Nodes. Allows real-time loading for LazyGraphs. Can be deleted and reloaded at any time depending on the needs.

Constructor & Destructor Documentation

proland::LazyNode::LazyNode	(	Graph *	owner,
		NodeId	id,
		double	x,
		double	y
	)

Creates a new Node.

Parameters:

	owner	the graph containing this node.
	id	this Node's id (determined by LazyGraph).
	x	this node's X coord.
	y	this node's Y coord.

virtual proland::LazyNode::~LazyNode

(

)

[virtual]

Deletes this LazyNode.

Member Function Documentation

virtual void proland::LazyNode::addCurve

(

CurveId

c

)

[virtual]

Adds a Curve to the Curves list.

Parameters:

c

the id of the Curve to add.

Reimplemented from proland::Node.

virtual void proland::LazyNode::doRelease

(

)

[protected, virtual]

Calls the LazyGraph::releaseNode() method.

See Object::doRelease().

virtual NodeId proland::LazyNode::getId

(

)

const [virtual]

Returns this Node's Id.

For LazyNode, a NodeId is a unique number, assigned by the owner Graph, (in opposition to Nodes, for which Ids are a direct reference to the Node).

Reimplemented from proland::Node.

void proland::LazyNode::loadCurve

(

CurveId

c

)

[private]

Adds a Curve to the Curves list, but doesn't change the owner's cache.

Parameters:

c

the id of the Curve to add.

virtual void proland::LazyNode::removeCurve

(

CurveId

c

)

[virtual]

Removes a Curve from the Curves list.

Parameters:

c

the id of the Curve to remove.

Reimplemented from proland::Node.
