Examples of org.gephi.graph.api.Graph.addNode()

org.gephi.graph.api.Graph.addNode()
Add a node to the graph. Fails if the node already exists. @param node the node to add @return true if add is successful, false otherwise @throws IllegalArgumentException if node is null @throws IllegalMonitorStateException if the current thread is holding a read lock
