Enumerations

All the other container classes considered in this text have only one associated enumeration. When dealing with graphs, it is convenient to have two enumerations. Each of the following methods returns an Enumeration defines as follows:

getVertices
This method returns an enumeration that can be used to traverse the elements of tex2html_wrap_inline69999.
getEdges
This method returns an enumeration that can be used to traverse the elements of tex2html_wrap_inline70005.
