Examples of DirectedNode

org.geotools.graph.structure.DirectedNode
Represents a node in a directed graph. A directed node differentiates between adjacent edges that start at the node and those adjacent edges that terminate at the node. The former are referred to as "in" edges, and the latter "out" edges. @see DirectedGraph @author Justin Deoliveira, Refractions Research Inc, jdeolive@refractions.net @source $URL$

Examples of org.geotools.graph.structure.DirectedNode

    //remove edge from adjacent nodes
    m_in.removeOut(this);
    m_out.removeIn(this);
    
    //swap nodes
    DirectedNode tmp = m_in;
    m_in = m_out;
    m_out = tmp;
   
    //re add nodes
    m_in.addOut(this);
