## Detailed Description

Constant node class.

Only retrieval operations are allowed on both the node itself and its edges.

## Constructor & Destructor Documentation

LinkGraph::ConstNode::ConstNode | ( | const LinkGraph * | lg,
|  | NodeID | node
| ) |  |
| inline

Constructor.

Parameters

  lg | LinkGraph to get the node from.
  node | ID of the node.

## Member Function Documentation

ConstEdgeIterator LinkGraph::ConstNode::Begin | ( |  | ) | const
| inline

Get an iterator pointing to the start of the edges array.

Returns
  Constant edge iterator.

Reimplemented in LinkGraphJob::Node.

Definition at line 362 of file linkgraph.h.

References LinkGraph::NodeWrapper< const BaseNode, const BaseEdge >::edges, and LinkGraph::NodeWrapper< const BaseNode, const BaseEdge >::index.

Referenced by LinkGraphOverlay::RebuildCache().

ConstEdgeIterator LinkGraph::ConstNode::End | ( |  | ) | const
| inline

Get an iterator pointing beyond the end of the edges array.

Returns
  Constant edge iterator.

Reimplemented in LinkGraphJob::Node.

Definition at line 368 of file linkgraph.h.

References LinkGraph::NodeWrapper< const BaseNode, const BaseEdge >::edges.

ConstEdge LinkGraph::ConstNode::operator[] | ( | NodeID | to | ) | const
| inline

Get a ConstEdge.

This is not a reference as the wrapper objects are not actually persistent.

Parameters

  to | ID of end node of edge.

Returns
  Constant edge wrapper.

Reimplemented in LinkGraphJob::Node.

Definition at line 356 of file linkgraph.h.
