Member Function Documentation

create()

SimpleEdge aud.graph.SimpleEdge.create

(

)

Create new edge instance.

Must initialize any attributes introduced in subclasses of AbstractEdge.

Returns

edge instance

Reimplemented from aud.graph.AbstractEdge.

Reimplemented in aud.example.graph.MyEdge.

Definition at line 9 of file SimpleEdge.java.

                                       {
    return new SimpleEdge();
  }

getLabel()

String aud.graph.SimpleEdge.getLabel

(

)

get text description or null if there is none

Reimplemented from aud.graph.AbstractEdge.

Definition at line 12 of file SimpleEdge.java.

                                     {
    return label_==null ? super.getLabel() : label_;
  }

getWeight()

double aud.graph.SimpleEdge.getWeight

(

)

set edge weight

Returns

not-a-number (NaN) if undefined (default implementation)

Reimplemented from aud.graph.AbstractEdge.

Definition at line 19 of file SimpleEdge.java.

{ return weight_; }

Referenced by aud.example.graph.DijkstraShortestPaths.priority(), aud.example.graph.PrimMinimumSpanningTree.priority(), and aud.example.graph.IterativeDFS1.start().

Here is the caller graph for this function:

setLabel()

void aud.graph.SimpleEdge.setLabel

(

String

label

)

set label (default label if label==null)

Definition at line 17 of file SimpleEdge.java.

{ label_=label; }

Referenced by aud.util.GraphDemo.main().

Here is the caller graph for this function:

setWeight()

void aud.graph.SimpleEdge.setWeight

(

double

w

)

set weight

Exceptions

UnsupportedOperationException

if edges are not weighted (link hasWeight} returns false)

Reimplemented from aud.graph.AbstractEdge.
