Constructor Detail

NumberNeighborIterator

public NumberNeighborIterator(NumberGraph graph,
                              NumberNode startNode)

Construct an iterator for the neighborhood of startNode in the given graph.

Parameters:

graph - the graph where the nodes reside

startNode - the node where the iteration starts

Method Detail

getCurrNode

protected final NumberNode getCurrNode()

The current node which corresponds to the next neighbor in the iteration.

Returns:

Returns the currNode.

setCurrNode

protected final void setCurrNode(NumberNode currNode)

Set the next neighbor node to be returned in the iteration.

Parameters:

currNode - The currNode to set.

hasNext

public boolean hasNext()

Description copied from interface: EdgeIterator
