Examples of org.apache.airavata.xbaya.graph.GraphException

org.apache.airavata.xbaya.graph.GraphException
The GraphException class represents an Exception related to a Graph. Mostly, it is thrown when parsing a graph XML.

            throws GraphException {

                throw new GraphException("Nodes after " + startClass.getName()
